Where to find natural sulfur. How to make sulfur at home
A very interesting game about survival in the ocean Subnautica, fraught with many secrets. The main problem in the beginning and middle of the game is not knowing where to find the blueprints or, for example, where the Cyclops is. Such simple questions, but players still try to get answers to them if they themselves have not figured it out.
Let's take a look at what and where you can find in the game and how to get there today in this article.
Blueprints are special schemes with which you can create devices and various objects. At the very beginning of the game - your character already knows how to create certain things, but in order to get new ones - you will need to get these layouts.
So let's figure out where to find the drawings:
- You have a scanner. With it, you need to study all the possible fragments that you will find during the game. Using this "magic" scanner, study everything that can catch your eye (even fish). For example, try to scan a banal chair - and as a result you will be able to create it.
- Selection of items. The interesting thing is that if you pick up any item, you will immediately know how to create it. You can say that you are self-taught. For example, if you catch a fish, you will already know how to cook it deliciously.
- Data boxes. These items are scattered throughout the seabed. By opening them you can find chips. Here they contain important information for you.
Where is the drawing of the Cyclops
What everyone is looking for is a special boat that serves as a small base for the player, so that you can always feel calm. Inside you can find lockers in the amount of 5 pcs. and 18 units. storage.
The variety of the interface is simply amazing:
- Whole boat health hologram tracking
- Special compass
- Panel where you can always change the name or color scheme
- Engine start mode (basic)
- Camera control mode and quiet running
Where is sulfur
A special material that bears the name - Crystalline sulfur is the main component for use as an oxidizing agent and reducing agent. Let's see where you can find it:
- Inactive lava zone. The main place where you can find sulfur. In this place, it is enough to ensure its comfortable future.
- In the active lava zone. Here, similarly to the first option, there are whole heaps of sulfur.
- Lost river. Another habitat for sulfur. There you can not only meet the monster, but also get for yourself how much sulfur you need.
Where to find magnetite
A special resource that is not particularly difficult to obtain if you know where to look for it. Let's look at places where you can easily get magnetite.
- Caves of jellyfish mushrooms. You probably already know about this place. Most magnetite is located in this location.
- Look for this resource in the mountains. You are sure to find as many as you need.
- Lost river. Another location where you can successfully mine magnetite.
Where to find crystals
This rare type of resource is the main problem when searching for beginners. From it we can make valuable materials that will lead us to victory. Let's see where you can still find diamonds and how difficult it is to do it.
- Diamonds can be obtained by crushing pieces of slate.
- Be sure to search just on the seabed.
- Explore the walls of caves at great depths.
After the last update, large deposits of diamonds were removed from the game, because. carry a huge imbalance.
If you are interested in where you can find other resources, then we will definitely supplement this article. Just write in the comment what you are interested in and we will definitely update it during the day.
Today we will try to make our own matches, after which we will check how much they will differ from the purchased ones.
But first, a little history. The first similarity of matches appeared in ancient China. But those sources of fire served only to facilitate the ignition process and were the usual elemental sulfur, which was smeared on thin chips. In Europe, matches began to appear only in the 19th century and in their early form were dangerous. That is, they ignited from friction against any surface, which was dangerous, since they could also ignite when rubbing against each other inside the box. The first safety matches appeared only in 1855. They were invented by the Swedish chemist Johan Lundstrom. In principle, in this form, they have survived to this day almost unchanged.
It is these Swedish matches that we will make today.
For their manufacture we need:
1. Toothpicks from birch (better to use aspen straws)
2. Kebab skewers (for making larger matches)
3. Flame retardant (2% ammonium dihydrogen phosphate solution)
4. Paraffin (paraffin candle)
5. Finely ground sand
6. Sulfur
7. Gelatin (regular food)
8. Potassium Dichromate
9. Sodium alginate
10. Water
11. Potassium chlorate
12. Iron oxide or other inert dyes (optional)
13. Cardboard (for making a matchbox)
14. Red phosphorus
15. PVA glue
Making matches starts with the simplest - with ordinary wood. The wooden part of a match is called a straw. It is most often made from aspen, but in the absence of it, the author will use ordinary birch toothpicks as straws, as well as barbecue skewers for larger matches.
The first step in the production of matches is the impregnation of straws with flame retardant. This is a substance that prevents wood from smoldering. The fact is that after the combustion of wood, coal remains, which then continues to smolder and turn into light ash, which can cause a lot of inconvenience when it gets on clothes or something else.
To avoid trouble when using matches, the straws are impregnated with a two percent solution of ammonium dihydrogen phosphate, that is, an acid salt of ammonium and phosphoric acid.
After impregnation and drying, it is clearly seen that when the straw is burned, the formed coal no longer smolders, which is very convenient.
The author has quite ancient matches in his collection, which are over 100 years old. They were still made in Reval, which is the name of Tallinn in tsarist times before the 1717 revolution. They still burn perfectly, but still, due to the lack of flame retardant impregnation, the burnt match head quickly falls off and continues to smolder, which can cause a fire or even a fire.
So the impregnation of matches today is simply a necessary measure.
However, for the further production of matches, the straw still needs to be impregnated with a combustible substance, which will facilitate the ignition of the tree and take over most energy. Most often, ordinary paraffin is used for this. To do this, the author melted a paraffin candle and lowered a chopped wooden straw into hot paraffin. It turned out something like deep-fried paraffin wax and wooden chips.
The interesting thing is that the smell during this process was really pleasant, since the tree contains sugars, which, when roasted, give a sweet aroma. However, that's not all. After cooling the paraffin-soaked straw, the most important thing must be applied to its tip - the head of a match, which is called sulfur in common people. The so-called sulfur is a rather complex mixture, which can consist of 4 or 10 different substances.
And yes, do not be surprised, it is simply necessary to add sand to the mixture for the match head, which plays the role of a flame retardant. Otherwise, when ignited, the match will simply explode, or burn too quickly.
As a combustion catalyst, 1% potassium dichromate must also be added to the mixture, as well as 1% sodium alginate to improve the viscosity of the mixture.
Now add water and begin to gradually mix the main substances so that they become a homogeneous mass.
After everything has dissolved, we add the most important chemical to the mixture - potassium chlorate, which plays the role of a powerful oxidizing agent, that is, a substance that causes the mixture to burn.
Now all this is mixed again until smooth. Then water is added to achieve the desired viscosity and, in principle, everything. It remains only to apply this mass to the tip of the match.
To give the sulfur mass a color, part of the sand can be replaced with iron oxide or other inert dyes. While the matches are drying, it remains to do one more important part - the matchbox itself and the grater surface on which the matches will light up.
To create the same grating surface, a mixture of red phosphorus and other fillers is used in the form of the same sand, antimony sulfide and other reagents. But the author did it simply, did not stint on phosphorus and mixed it with PVA glue.
Then I smeared this mixture on the ribs of the box.
After the mixture has dried, the grater surface is ready. By the way, the matches have also dried up, so you can collect such an impromptu matchbox.
The author decided to brand these matches and called them "Thoisoiki".
After everything is assembled, the moment of truth comes. Let's check if such a homemade match will light up on such an impromptu box.
She's on fire. Marvelous! As you can see, homemade matches turned out to be no worse than purchased ones. chemical reactions participating in this process are quite simple. First, when the match head is rubbed against the surface of red phosphorus, together with contact, potassium chlorate actively oxidizes red phosphorus. And from this temperature, the reaction of sulfur and potassium chlorate begins in the match head. After that, gelatin enters the reaction. From the resulting heat, the paraffin, which is impregnated with a match, boils. After that, it lights up, setting fire to the wooden straw itself.
And now let's compare homemade matches under a microscope and those made at the factory.
Sulfur is an element periodic system chemical elements and belongs to the group of chalcogens. This element is an active participant in the formation of many acids and salts. Hydrogen and acid compounds contain sulfur, usually in the composition of various ions. A large number of salts, which include sulfur, are practically insoluble in water.
Sulfur is a fairly common element in nature. According to its chemical content in earth's crust she was assigned the sixteenth number, by being in the reservoirs - the sixth. It can occur both in the free and in the bound state.
The most important natural minerals of the element include: iron pyrites (pyrite) - FeS 2, zinc blende (sphalerite) - ZnS, galena - PbS, cinnabar - HgS, antimonite - Sb 2 S 3. Also, the sixteenth element of the periodic system is found in oil, natural coal, natural gases, and shale. Finding sulfur in aquatic environment appears to be sulfate ions. It is her presence in fresh water is the cause of permanent rigidity. It is also one of the most important elements of the life of higher organisms, is part of the structure of many proteins, and is also concentrated in the hair.

Sulfur ore
It cannot be said that the free state of sulfur in nature is a frequent occurrence. Native sulfur is quite rare. Often it is one of the components of some ores. Sulfur ore is a rock that contains native sulfur. Sulfur inclusions in rocks can be formed together with accompanying rocks or later. The time of their formation affects the direction of prospecting and exploration work. Experts identify several theories of sulfur formation in ores.
- Theory of syngenesis. According to this theory, sulfur and host rocks were formed simultaneously. The place of their formation were shallow basins. The sulfates contained in the water were reduced to hydrogen sulfide with the help of special bacteria. Further, it was raised up to the oxidizing zone, in which hydrogen sulfide was oxidized to elemental sulfur. She sank to the bottom, settling in silt, which after a while turned into ore.
- The theory of epigenesis, which states that the formation of sulfur inclusions occurred later than the main rocks. In accordance with this theory, it is believed that groundwater penetrated into the rock mass, as a result of which the water was enriched with sulfates. Further, these waters came into contact with oil or gas deposits, which led to the reduction of sulfate ions with the help of hydrocarbons to hydrogen sulfide, which, rising to the surface and oxidizing, released native sulfur in the voids and cracks in the rocks.
- The theory of metasomatism. This theory is one of the subspecies of the theory of epigenesis. Currently, it is increasingly finding confirmation. Its essence lies in the transformation of gypsum (CaSO 4 -H 2 O) and anhydrite (CaSO 4) into sulfur and calcite (CaCO 3-). The theory was proposed by two scientists Miropolsky and Krotov back in the first half of the twentieth century. A few years later, the Mishrak deposit was found, which confirmed the formation of sulfur in this way. However, the process of transformation of gypsum into sulfur and calcite remains unclear so far. In this regard, the theory of metasomatosis is not the only correct one. In addition, today there are lakes on the planet with syngenetic sulfur deposits, however, gypsum or anhydrite were not found in the silt. These lakes include Sulfur Lake, located near Sernovodsk.
Thus, there is no unambiguous theory of the origin of sulfur inclusions in ores. The formation of matter largely depends on the conditions and phenomena occurring in the earth's interior.
Sulfur deposits
Sulfur is mined in the places of localization of sulfur ore - deposits. According to some data, the world reserves of sulfur are about 1.4 billion tons. To date, sulfur deposits have been found in many parts of the Earth - in Turkmenistan, in the USA, the Volga region, near the left banks of the Volga, which lie from Samara, etc. Sometimes a band of rock can extend for several kilometers.
Texas and Louisiana are famous for their large sulfur reserves. Distinguished by their beauty, sulfur crystals are also located in Romagna and Sicily (Italy). The homeland of monoclinic sulfur is the island of Vulcano. Also, Russia, in particular the Urals, is famous for the deposits of the sixteenth element of the periodic system of Mendeleev.
Sulfur ores are classified according to the amount of sulfur they contain. So, among them, rich ores (from 25% sulfur) and poor ones (about 12% of the substance) are distinguished. Sulfur deposits, in turn, are divided into the following types:
- Stratiform deposits (60%). This type of deposits is associated with sulfate-carbonate strata. Ore bodies are located directly in sulfate rocks. They can reach hundreds of meters in size and have a thickness of several tens of meters;
- Salt dome deposits (35%). For of this type gray sulfur deposits are characteristic;
- Volcanogenic (5%). This type includes deposits formed by young and modern structure. The shape of the ore element occurring in them is sheet-like or lenticular. Such deposits may contain about 40% sulfur. They are characteristic of the Pacific volcanic belt.
Sulfur mining
Sulfur is mined by one of several possible ways, the choice of which depends on the conditions of occurrence of the substance. The main ones are only two - open and underground.
Open pit sulfur mining is the most popular. The entire process of extracting a substance by this method begins with the removal of a significant amount of rock by excavators, after which the ore itself is crushed. The resulting ore blocks are transported to the factory for further enrichment, after which they are sent to the enterprise, where sulfur is smelted and substances are obtained from concentrates.
In addition, the Frasch method is also sometimes used, which consists in smelting sulfur while still underground. This method it is advisable to use in places of deep occurrence of the substance. After melting underground, the substance is pumped out. For this, wells are formed, which are the main tool for pumping out the molten substance. The method is based on the ease of melting of the element and its low density.
There is also a centrifuge separation method. However, it has one big drawback, based on the fact that the sulfur obtained using this method has a lot of impurities and requires additional purification. As a result, the method is considered quite expensive.
In addition to these methods, sulfur extraction in some cases can also be carried out:
- borehole method;
- steam-water method;
- filtration method;
- thermal method;
- extraction method.
It is worth noting that, regardless of the method used during the extraction of matter from the bowels of the earth, special attention must be paid to safety. This is due to the presence, together with sulfur deposits, of hydrogen sulfide, which is toxic to humans and can ignite.
Sulfur in Conan Exiles is an auxiliary ingredient required for some crafting, including the creation of steel ingots - the main resource of the mid-late stages of the game.
Alas, many players do not know where to get sulfur in Conan Exiles, especially in large quantities. Now we will try to answer this question.
Map
One of the best places in the game with stocks of this resource is marked on the map:
The location has a large number of deposits, and here you can easily get sulfur in Conan Exiles. However, be careful - the area is filled with poisonous fumes, which gradually damage the character. However, this damage is quite low and you can get a couple of hundred units of the resource without fear of dying.
Additional ways
In addition, sulfur in Conan Exiles can be obtained from Bladespire, creatures that live in the desert near the rocks. After killing the monster, use the pickaxe and with some probability you will get a valuable resource. However, the extraction of sulfur from stonehorn is a long business, as it falls very little.
Another option where you can get sulfur in Conan Exiles is by killing human NPCs, which can also drop some of the resource.
- During the experiment, place a container with water nearby.
- Place the dry fuel burner (included in the starter kit) on the tray. Do not touch the burner immediately after the experiment - wait until it cools down.
- Don't forget to wear safety goggles!
General safety rules
- Avoid getting chemicals in your eyes or mouth.
- Do not allow people without goggles, as well as small children and animals, to the experiment site.
- Keep the experimental kit out of the reach of children under 12 years of age.
- Wash or clean all equipment and accessories after use.
- Make sure all reagent containers are tightly closed and properly stored after use.
- Make sure all disposable containers are properly disposed of.
- Use only the equipment and reagents supplied in the kit or recommended in the current instructions.
- If you have used a food container or experiment utensils, discard them immediately. They are no longer suitable for food storage.
First Aid Information
- If reagents come into contact with eyes, rinse eyes thoroughly with water, keeping eyes open if necessary. Seek immediate medical attention.
- If swallowed, rinse mouth with water, drink some pure water. Don't induce vomiting. Seek immediate medical attention.
- In case of inhalation of reagents, remove the victim to fresh air.
- In case of skin contact or burns, flush the affected area with plenty of water for 10 minutes or longer.
- If in doubt, consult a doctor immediately. Take a chemical reagent and a container from it with you.
- In case of injury, always consult a doctor.
- Improper use of chemicals can cause injury and damage to health. Carry out only the experiments specified in the instructions.
- This set of experiments is intended only for children 12 years of age and older.
- The abilities of children differ significantly even within an age group. Therefore, parents conducting experiments with their children should decide at their own discretion which experiments are suitable for their children and will be safe for them.
- Parents should discuss safety rules with their child or children before experimenting. Particular attention must be paid to the safe handling of acids, alkalis and flammable liquids.
- Before starting experiments, clear the place of experiments from objects that may interfere with you. Storage of foodstuffs near the test site should be avoided. The test site should be well ventilated and close to a faucet or other source of water. For experiments, you need a stable table.
- Substances in disposable packaging should be used completely or disposed of after one experiment, i.e. after opening the package.
First, you can find hemotropin in many stores, such as tourist or hardware stores. Most likely, there it will be sold as "dry fuel" or "dry alcohol". However, there is an easier option. Take an ordinary household candle and use it as a heat source.
Sulfur caught fire
Sulfur vapor is fairly flammable. If they catch fire, this will not interfere with the experiment, however, complete burnout of sulfur should be avoided. But, as a rule, sulfur ignites only when almost all the contents of the thimble have already melted and turned black. Therefore, heat the sulfur for about a minute more and pour the molten black substance into the water.
Sulfur turned black, but does not pour out of the thimble
There is nothing wrong with that. At a certain temperature - about 190oC - black plastic sulfur is very viscous. At higher temperatures, it becomes fluid. Just heat the thimble with sulfur for a couple more minutes.
After cooling with water, the sulfur turned yellow or black-yellow
This means that you hurried a little and poured the sulfur into the water before it all melted and turned into a black viscous liquid. You can repeat the experiment using a second jar of sulfur.
But do not rush to throw away sulfur after a "bad" experience. Wait a couple of days for it to become a yellow powder again. Now you can repeat the experiment!
The figurine turned yellow and crumbled in just a few days
You did everything right. Sulfur crystallization is a complex process, the duration of which strongly depends on how much the substance was heated initially.
- Prepare a glass beaker. Fill it with water and leave it next to the experiment area.
- Take a dry fuel burner from the starter kit. Place the metal cup on the burner as shown in the picture.
- Pour all the dry fuel from the jar (0.5 g) into the center of the metal container.
- Attach the tweezers to the thimble as shown.
- Fix the thimble.
- Make sure the thimble is securely fastened at a sharp angle.
- Pour all the sulfur from the jar (2 g) into the thimble.
- Ignite the dry fuel on the burner.
- Melt sulfur on an open fire until it turns black. Be careful not to lower the thimble too deep into the flame so that the sulfur does not ignite.
- During melting, sulfur can ignite - this is acceptable. However, burnout should be avoided. Do not try to blow out the sulfur if it is on fire! This will lead to more active combustion.
- Pour all the melting (or burning) sulfur into a prepared glass of water.
- In water, sulfur will cool almost instantly. Take out the pieces of black sulfur and make a figurine out of it.
- After about a week, the figure will noticeably turn yellow.
- After a month, the figurine will turn completely yellow and crumble.
The yellow powder of rhombic sulfur S8, when heated, transforms into a black viscous mass of plastic sulfur S∞. After cooling with water, sulfur can be molded into a figurine. Gradually unstable plastic sulfur will turn back into rhombic. The figurine will turn yellow again and crumble.
Dispose of experiment waste with household waste.
When heated, it changes internal structure sulfur. From a crystalline form stable at room temperature yellow color it passes into a plastic form that does not have a definite internal structure. At the same time, the color of the substance also changes: at first, yellow sulfur becomes red-brown, and then black.
At room temperature, the only stable form of existence of sulfur is the so-called rhombic sulfur. It consists of crystals formed by circular S8 molecules, shaped like a crown.
When heated above 119oC, the sulfur crystals melt to form a red-orange liquid, also composed of S8 molecules. With a further increase in temperature, the ring sulfur molecules break, forming "threads" of atoms connected to each other.
It is the appearance of linear molecules that gives molten sulfur a black color. These "threads" can connect with their free ends to each other, forming very long molecules. As a result, liquid sulfur thickens due to the “sluggishness” of large molecules.
They can be compared to threads: the longer they are, the easier they are tangled with each other. If you heat a black viscous liquid to 187oC, it will become as thick as possible (plastic sulfur).
At higher temperatures, the bonds within the long molecules break down again, and the mass becomes thinner. Black sulfur becomes maximally liquid at 400oC, and boils at 445oC.
Be very careful when melting sulfur! The ignition temperature of sulfur in air is lower than the boiling point, and is only 360oC. Sulfur splashes, which can fly out of the liquid, immediately ignite and can be a significant hazard.
Why is it necessary to cool sulfur with water?
Water is needed for very rapid cooling of plastic sulfur to room temperature. Only under this condition can long chains of sulfur molecules be preserved for some time. This will result in a uniformly black figurine.
If you cool plastic sulfur gradually, simply by stopping heating, it will again turn into yellow crystals of rhombic sulfur, and quite quickly.
If the black liquid resulting from melting is cooled very quickly, it will become like plasticine. Long molecules simply do not have time to collapse and form S8 ring molecules.
Cold water does not interact with sulfur in any way, acting only as a coolant.
Scary word - "allotropy"
Allotropy is the property of the same simple substance to exist in two or more forms that differ from each other in structure and properties. These different forms called allotropic modifications.
It is important not to confuse allotropic modifications with simple transitions between solid, liquid and gaseous forms, as well as with simple grinding.
Yellow sulfur crystals and black plastic mass are two allotropic modifications of sulfur.
The existence of several allotropic modifications of a substance is associated with a different composition and structure of the molecules of the substance or with the method relative position atoms or molecules inside crystals. Black viscous plastic and yellow crystalline rhombic sulfur - far from the best a prime example in the difference in the properties of two allotropic modifications of the same substance.
Carbon (C) can boast of the maximum variety of forms of existence. Graphite, diamond, soot are the most well-known allotropic modifications of carbon.
Despite the common chemical formula (C), these substances not only look completely different, but also have completely different physical and even chemical properties.
But they consist of exactly the same atoms, just differently located relative to each other!
In addition to those listed, there are many other allotropic modifications of carbon. Their list is growing, because scientists are constantly discovering more and more new ones.
In terms of the number of known allotropic modifications, sulfur ranks second in the world after carbon. But it has much less stable forms.
Why does the figurine change its color over time?
A substance always tends to change into a stable form. Black plastic sulfur is not stable under normal conditions. Therefore, it gradually changes its internal structure, crystallizes and turns into yellow rhombic sulfur.
The black figurine consists of very long sulfur molecules Sn. Such an internal structure of matter is stable only at high temperatures. Temporarily, it can only be stabilized by rapid cooling. At room temperature, long molecules gradually "break", and their fragments form ring molecules S8.
The latter form crystals of rhombic sulfur, the only allotropic modification of sulfur that is stable at room temperature. In addition to changing color, there is also a change in other physical properties. The figurine becomes fragile and gradually crumbles.
This process cannot be prevented, but it is very interesting to observe.
You can try to "catch" sulfur in a rather unstable form - red, slightly viscous and somewhat similar in consistency to honey.
To do this, you need to slowly heat the yellow crystalline sulfur. As soon as the sulfur inside the thimble turns red, tip its contents into the water.
If everything worked out, the red sulfur will harden into long, viscous drops in water.
If all the urotropine has already been used up, you can heat the sulfur with a regular household candle.
Again and again
The second development of experience is the repetition of the experiment. Yes, you heard right! We have already once turned yellow crystalline sulfur into black and viscous.
After waiting 3 - 4 weeks, you will see that it has become yellow and powdery again. Now heat the yellow powder.
See? He again became a black viscous liquid! The reversibility of transitions between different states is one of the interesting properties of sulfur.
The transition of rhombic sulfur to plastic is very difficult. At the same time, black plastic sulfur is not the final form of existence of molten sulfur! When heated, a whole series of rearrangements of sulfur atoms occurs relative to each other with the formation huge amount various structures.
For brevity, allotropic modifications of sulfur are often referred to as Sx, where the letter of the Greek alphabet is written instead of x.
Rhombic sulfur (stable yellow crystals) is referred to as Sα (alpha sulfur). It is the main form of existence of this substance up to 95.5oC. At temperatures from 96 to 119oC, sulfur is in the Sβ modification (beta-sulfur, prismatic or monoclinic sulfur).
Both of these allotropic modifications consist of S8 molecules, but have crystals of different configurations. At the same time, monoclinic sulfur crystals are practically colorless. Sulfur melts at 113-119oC. The melt is very fluid and consists of exactly the same molecules as the solid forms mentioned above.
Such an allotropic modification is designated as Sλ (lambda-sulfur).
Plastic sulfur - Sµ (mu-sulfur), which is a thick liquid consisting of linear molecules - is formed from lambda-sulfur at temperatures above 160oC.
At 187oC, its molecules reach their maximum length, and upon further heating they decompose into short chains, forming a liquid allotropic modification Sπ (pi-sulfur).
It is pi-sulfur that is the final form of the existence of sulfur in molten form. Sulfur vapors are mainly represented by ring molecules S8.
After the termination of heating and with gradual cooling, the chain of transitions between the allotropic modifications of sulfur runs in the opposite direction.

Pine sulfur - a natural bactericidal agent
Pine sulfur is a true bactericidal and disinfectant, melted from the bark of Scots pine, it has a set of all the useful and healing properties that the pine itself has.
About the healing properties of pine, its life-giving power, you can read in the article: Scotch pine and its amazing healing power. How is pine sulfur obtained? I'll tell you everything in order.
The wood of the Scots pine is rich in resin, which constantly flows from cracks in the bark, which are obtained naturally.
Thus, the pine heals its wounds and injuries, filling them with life-giving and bactericidal resin, thereby protecting the tree from drying out and damage by fungi. The transparent resin of coniferous trees is popularly called resin.
What is pine sulfur
Gum can be seen on the trunks of fir, pine, larch, cedar - all coniferous trees. Resin is a solution of resin mixed with essential oil.
At first it is liquid-viscous, gradually the essential oil evaporates and the resin thickens to a granular mass. Under the influence of the sun and wind, the resin dries out, hardens and turns into growths in the form of a white or yellowish crystalline mass.
Siberians call such crystalline outgrowths gray pine. Sulfur growths can be carefully "picked" with a knife without damaging the tree itself. Basically, raw sulfur is mined during logging, it is cut down from sawn trees with a hatchet along with pine bark, which is called currant. On currants, pine sulfur is still raw.
How is sulfur obtained?
To chew it like chewing gum, it needs to be “drowned”. Previously, pine sulfur was heated in special cast-iron pots. More water was poured into the cast-iron, and a second cast-iron was placed on top of it with a hole covered with a small metal strainer.
Chopped currants with sulfur growths were placed in the upper cast-iron, and the cast-irons were placed in a hot oven on coals. The sulfur on the currants melted and flowed down to the bottom of the upper pot and through a strainer into the lower pot with water. To languish in the oven, sulfur should be 1-1.5 hours.
Melted sulfur was taken out of hot water, crushed and pulled out by hand already in cold water until it no longer sticks to your hands. Then it was rolled into bundles and cut into cubes. The blocks dried up and became hard, like pebbles. From above, such bars are brown, and inside the sulfur is yellowish-brown, with an amber sheen.
As a child, I myself had to heat sulfur. We replaced cast iron pots with ordinary tin cans, otherwise the technology is the same.
In the village, we bought such bars (lumps) weighing 50 grams for 5 kopecks, now you can also buy sulfur and pine and larch sulfur on the market, a lump of 30 grams costs 60 rubles, cedar sulfur is more expensive - up to 100 rubles.
AT recent times the market is increasingly selling fire sulfur, which is heated right in the forest, on fires and packed in small plastic bags or blister packs. This sulfur smells like smoke and many people like it. Not for me.
In the photo - cedar sulfur:
The broken heating technology immediately reminds of itself. Fire sulfur is always soft, sticky and spreads into a cake. It sticks to the teeth, although this does not affect the healing properties of sulfur.
Real pine sulfur, stewed in an oven, keeps its shape, which is why it used to be sold in lumps.
Biting off a piece of it with a crunch, first you need to hold it in your mouth a little to soften it, and then chew it.
Such sulfur is stored in jars of cold water, otherwise it dries up and crumbles into powder during chewing.
The healing properties of sulfur
Now sulfur is also sold in pharmacies, it is called Smolka, Zhivitsa, it is packaged in a blister, like tablets. Sulfur of coniferous trees is very useful. It contains the same trace elements as the resin. Rich in phytoncides and vitamins "C", "B1", "B2", "P", "K", carotene.
And what a fragrant she is!
- It has bactericidal and disinfectant properties,
- destroys microbes in the oral cavity and nasopharynx,
- Therefore, it was used as a means to increase immunity,
- cleans teeth from food particles,
- freshens breath,
- relieves toothache, for this, a piece of sulfur was kept in the mouth, behind the cheek, for toothache.
And if you chew sulfur after each meal, for 10-20 minutes, then you can generally forget about dental and gum disease. And also, you can forget about diseases of the throat and upper respiratory tract, but I remind you if sulfur is chewed daily, and not from case to case.
Since it is harder than chewing gum, it strengthens the teeth by creating tension in them. A piece of sulfur, “for one chew” is enough for one day, after which it becomes “old” - that’s what the old people said, i.e. simply put, it changes color, becomes brown-brown and crumbles into powder.
Pine sulfur ages only because it absorbs food particles, collects microbes, cleaning and disinfecting the oral cavity.
Chew sulfur for health!

MiscellaneousWhere to get sulfur
In general, the question of how to get sulfur is quite interesting and entertaining, if only because sulfur is part of not only rocks and natural rocks and is necessary for human life, but is also part of the human body itself. Sulfur is a typical non-metal and combustible chemical element. Since ancient times, people have used sulfur in everyday life and found ways to extract it. At this point in time, many ways to obtain sulfur have been discovered.
The most common way to obtain sulfur is the method proposed back in 1890 by G. Farsh. He proposed to melt sulfur underground and pump it to the surface with the help of wells.
The idea was that sulfur is a fusible chemical element, the melting point of which is 113 0C, which greatly facilitates the process of sublimation.
On the basis of the proposed idea, various methods for obtaining sulfur from sulfur ores and mountain deposits arose:
- steam water,
- filtration,
- thermal,
- centrifugal,
- extraction.
All these methods and methods are widely used in the mining industry.
Also popular is the method of extracting chemically pure finely dispersed sulfur from natural gas, which is an ideal raw material in the chemical and rubber industries.
Since sulfur is contained in large quantities in gaseous form in natural gas, during gas production it settles on the walls of pipes, quickly disabling them. Therefore, a way was found to capture it immediately after gas production.
How to get sulfur oxide
Sulfur oxide (VI) - highly volatile colorless liquid with a suffocating pungent odor. The simplest and most common ways to obtain sulfur oxide:
- In the presence of a catalyst, sulfur oxide (IV) is oxidized by heating with air, thereby obtaining sulfur oxide (VI).
- Thermal decomposition of sulfates.
- Sulfur oxide (IV) is oxidized with ozone to obtain sulfur oxide (VI).
- In the oxidation reaction of sulfur oxide (IV), nitrogen oxide is used, thereby obtaining sulfur oxide (VI).
How to get sulfur oxide 4
Sulfur oxide (IV), or sulfur dioxide - colorless gas with a characteristic suffocating odor. In laboratory conditions, sulfur oxide (IV) is obtained by the interaction of sodium hydrosulfite with sulfuric acid or by heating copper with concentrated sulfuric acid.
Also in nature and laboratory conditions, a method for producing sulfur oxide (IV) by the action of strong acids on sulfites and hydrosulfites is common. As a result of this reaction, sulfurous acid is formed, which immediately decomposes into water and sulfur oxide (IV).
An industrial method for producing sulfur oxide (IV) is the burning of sulfur or the burning of sulfides - pyrite.
How to get sulfur from hydrogen sulfide
The method of obtaining sulfur from hydrogen sulfide is carried out in laboratory conditions. It should be noted right away that a similar method of obtaining sulfur should be carried out with all safety measures, since sulfur

Once such a booze has gone
Gunpowder consists of three components: Saltpeter is a simple and affordable thing, but it was terribly lacking. You can recall the revolutionary decrees “every poop for the cause of the revolution” or Louis, who privatized dovecotes. Coal is also simple, trees grow everywhere. The technology has been developed for thousands of years.
But where did they get the sulfur? There are very few deposits of native crystalline sulfur, the most famous in Sicily. Where else? Not even so - not where, but how? There has never been a shortage of sulfur, which means that they were mined from something that was pasture.

I delved into this issue a bit, sulfur was everywhere in Europe in abundance. Sulfur water springs - besieged on branches (Germany), and natural deposits - Italy, Spain, the Caucasus + Carpathians ... and somewhere in the middle zone of Russia there is, almost on the Volga (there is also the famous "Saltpeter" settlement and a source of natural sodium saltpeter ).

The world used to be much bigger
According to my information, sulfur is formed as an associated mineral in gypsum. But for the powder industry, IMHO, this is not enough.
Agricola: "Sulfur is extracted from sulfur ores or mixtures containing sulfur. Water is poured into lead vats and boiled until sulfur is released. If a mixture of such sulfur with iron filings is heated, put in pots and covered with clay and purified sulfur, then another type of sulfur will be obtained , called "horse sulfur".

Smoke bombs from soda: preparation, recipes, safety precautions
The smoke bomb is a versatile item that has several uses. With its help, you can protect yourself, for example, from mosquitoes, and get rid of a fungus or harmful insects in a closed room.
Varieties and technologies
Two main classifications can be distinguished:
Long-acting smoke exhausts are presented in the form of a body with holes for smoke to escape. Instantaneous smoke bombs are in the form of a cartridge that contains a flammable chemical component. The duration of the smoke supply, as well as its density, will depend on the amount and constituent elements of the filler.
With saltpeter
This method is relatively labor intensive. When burning, the product emits a large amount of dense smoke.
The following components are needed:
- ammonium nitrate;
- ordinary newspaper sheets;
- liter plastic bottle;
- water;
- sprayer.
Cooking:
Prepare a solution on the basis that about 300 grams of saltpeter are used per 1 liter of water. Further algorithm of actions:
- Take a liter container and fill a third with ammonium nitrate. Fill the rest with water.
- Wait for the complete dissolution of the saltpeter. At the end of the reaction, foam will appear on the surface of the water. Pour it carefully into the sink.
- Screw an ordinary flower sprayer onto the bottle and moisten a sheet of newspaper. Place a dry sheet on a wet sheet, soak it with a spray. Repeat the procedure for all newspaper elements. The resulting solution should be enough for about 35-40 sheets.
- Turn over the stack of paper and leave it to dry completely. Never dry paper in the sun or near open flames, heaters, burners, etc.
- Wind the dried sheets and crumple them into one "cartridge". Pay attention that the sheets are as close as possible to each other. Wind up the required number of sheets, and fix the resulting product tightly with adhesive tape.
The device is ready to use.
Saltpeter during smoldering and burning produces a large amount of thick and acrid smoke.
Figure 1 - Saltpeter chimney during use.
: Details of the manufacture of the device and its testing.
With salt
This manufacturing method is the easiest, it will take no more than 5-10 minutes.
Components:
- paper or old newspaper sheets.
- finely crushed salt (large crystals can shoot off during combustion).
- scotch.
Cooking:
- Crumple the paper or newspaper into a ball, and then unfold it back.
- Sprinkle salt around the middle. Its quantity depends on the desired size of the flue and the amount of paper.
- Fold the salt sheets back and secure with tape.
To use, set fire to a lump in any convenient place and discard to a safe distance. It is not recommended to hold the product in your hands, because salt can shoot along with pieces of burning paper.
How to make according to the recipe is shown in the video.
with soap
The process of preparing a smokehouse according to this recipe is quite long, the craft smokes for a long time, but not much.
For a smoke bomb take:
- soap (household);
- paper or newsprint;
- adhesive tape or cling film;
- 5 liters of water (for one bar of soap).
Cooking method:
- Grind the soap, and pour the resulting soap shavings into a saucepan with water and heat until dissolved.
- The mass should be thick. Soak sheets of paper gently in the solution. Do this carefully to avoid tearing the paper. Air will collect in these places, which will give more fire, but less smoke.
- Take out the sheets and dry them. You can use a fan to speed up the process. Do not dry paper on heaters, batteries or over gas stoves. This may lead to premature ignition.
Roll the dried sheets into a "cartridge" or crumple into a ball shape. Tape is used to secure the structure.
The subtleties of cooking are shown in the video.
With analgin and hydroperite
Powdered components during combustion intensively emit a lot of smoke.
The method will require the following ingredients:
- analgin;
- hydroperite;
- container (preferably metal).
To obtain a flue with thick and acrid smoke, the following algorithm is followed:
- Take 2 tablets of analgin, grind to a powder state.
- Bring the same amount of hydroperite to a mushy mass.
- Pour the resulting powder from two tablets into a common container, mix.
For combustion of the resulting composition and the release of smoke, the temperature of the human body is sufficient. Be careful when handling the container.
Detailed video guide.
With activated carbon, manganese and matches
When burning, the mixture will sparkle in purple or dark red, which looks very beautiful and spectacular.
List of ingredients for this method:
- activated carbon (packaging);
- dry potassium permanganate powder (2 sachets of 12–15 g each);
- 2 box of matches.
Cooking:
- Remove the charcoal tablets from the package and grind them to a powder. Next, pour the resulting composition into a container.
- Add 2 bags of potassium permanganate powder to activated charcoal.
- Take matches and clean off the sulfur heads from them. Pour into a common container with coal and potassium permanganate.
The resulting mixture must be set on fire and as soon as possible move to a safe distance (at least 10-15 meters). During combustion, thick smoke with a pungent odor will pour out of the container, sparks about two meters high will fly off.
With foam and aluminum foil
Component parts burn for quite a long time, while emitting caustic clouds of smoke.
For this method take:
- foam rubber (bar shape);
- nitrocellulose varnish (hereinafter "NC" varnish);
- foil.
Action algorithm:
- Take the foam rubber and push it into the bottle with the "NC" varnish.
- Use a wooden stick to squeeze out excess varnish from the foam rubber, pressing a piece of material against the walls of the can.
- Take out the foam rubber and dry it on a sheet of newspaper. It is better not to use a battery for this purpose, as there will be an unpleasant smell throughout the room.
- Wrap the foam block tightly and securely with aluminum foil.
- Attach a wick for remote ignition.
The video demonstrates the preparation and verification of the composition according to this recipe, as well as a comparison with the composition of sawdust, machine oil and ammonium nitrate.
With sulfur, saltpeter and coal
A large amount of thick smoke is released when the chimney is smoldering according to this recipe.
For this smoke bomb take:
- sulfur;
- saltpeter;
- Activated carbon;
- water;
- a tube made of cardboard (like from paper towels);
- paper.
Preparation method:
- In one container, mix 3/6 of ammonia, 1/6 of sulfur and 2/6 of powdered activated carbon.
- Combine all components together, add water and mix further until a thick, viscous solution is obtained.
- Put the solution in a warm place or in the sun, bring to dryness.
- Grind the resulting dry mass into a homogeneous powder.
- Take a cardboard tube and seal it on one side. Pour the resulting powder into a tube, and at the other end, tightly lay newspaper sheets. It is important that the powder in the tube is in a tight and compressed state.
For reliability and convenience, the resulting structure can be wrapped with tape.
From the line
Fast and easy way get a lot of thick smoke from improvised means.
To do this, take:
- school ruler made of plastic;
- matches;
- Matchbox.
Cut the ruler into small pieces and carefully place in a matchbox. Close the full matchbox, leaving a small opening.
Then cut a piece of a ruler of small length and insert into the hole. This piece will serve as a wick, so place it in such a way that it is in contact with the filler of the box.
The smoke bomb from the school line is ready to be ignited.
Figure 2 - Instead of a plastic wick, a piece of paper is used.
Detailed production and testing of the device is shown in the video.
From insects
Insect smoke bombs are very popular and are used to disinfect greenhouses, basements, country houses, cottages. There are many special checkers on sale with a special chemical composition which insects do not like. The most popular: Mukhoyar, Climate, Hephaestus, Quiet Evening, Fas.
In special checkers, the main active ingredient is sulfur. The above describes several methods for preparing a flue using sulfur. The effect will not be as instant as in the case of specialized tools, but still show the desired result.
Without paper
There are several ways to make fluff without paper. For example, with the use of Analgin and Hydroperit, or from a simple school line. All of these methods are detailed in the sections above. These cooking methods are less labor-intensive, but still do not always give a sufficient amount and volume of smoke.
An interesting version of creating checkers without paper, with a lot of smoke is shown in the video.
Colored with soda
A rather laborious process in the manufacture of a flue, as a result, saturated colored smoke is released during combustion.
For cooking you will need:
- ordinary soda (0.5 tsp);
- sugar (50 g);
- potassium nitrate (60 g);
- dye of the desired color (3 tsp);
- bucket or other similar container;
- cardboard tubes from paper towels;
- rope.
Cooking method:
- Take a bucket or other metal container, mix sugar with saltpeter. Place over low heat and stir slowly but regularly. Make sure that the mass does not burn.
- Bring the mass to homogeneity. When it reaches the desired consistency and becomes golden in color, add soda and dye. Stir until foam appears.
- Remove from heat, cool to room temperature.
- Take cardboard tubes, seal one of the sides so that it is airtight. Pour the entire solution into the resulting container, and insert a thin wooden stick in the center. It is important to fill the container so that no empty air spaces appear. Leave the structure to dry completely (about a day).
Then pull out the stick and replace it with a string that will serve as a wick. When igniting and using, strictly follow the safety precautions.
