Description of the mineral and its properties
For many, the word "talc" has associations with which they are used to powder skin folds in babies. This hygiene product contains a powder of this element, aromatic substances and dyes. And really, what is talc? This is an amazing mineral with a unique chemical formula, which is formed at considerable depths at high temperatures.
Talc, which is mined in different deposits, has differences in its structure and chemical composition. There are minerals with a large percentage of magnesium, chromium and aluminum, and there is also an increased amount of iron and nickel ions. This substance is greasy to the touch and very soft. It does not burn, withstands high temperatures does not melt or crack. What is talc and what is it, we figured it out a little. Now let's talk about its application in various industries.
The use of talc in industry
Even in ancient times, this amazing mineral was used in the manufacture of jewelry and dishes. Items with its content were found by archaeologists during excavations. In modern times, talc is used in various fields of production. So, in cosmetology and the perfume industry, it is used as an additive in the manufacture of powder, eye shadow, and soap. In medicine, it is used to make powder for the treatment of diaper rash. Talc is used as a substance to prevent sticking of rubber gloves. This mineral is no less important in paper production. It is necessary in the manufacture of thick paper to obtain a smooth surface. In textile works, harsh fabrics are bleached with a solution of this mineral. The paint and varnish industry also cannot do without this amazing substance, because thanks to it waterproof paints appeared. When firing ceramic products, talc is added. It is also present in colored pencil leads and acts as an excellent heat and electrical insulator.
Talc in cosmetics
Cosmetology is one of the industries in which this mineral is widely used. It has antibacterial and absorbent qualities.

/ Mineral Talc
Talc is a common mineral, silicate, pyrophyllite-talc group. Varieties: Agalite (fine-fiber talc), For the first time, a description of a stone under the indicated name was found as early as 1546. Talc was used by George Agricola - the great scientist of the Renaissance. He applied the name "talc", describing the properties of the mineral and calling it pure and white. Even then, it was used in stone-cutting work, but only in some compounds and varieties that could be found in the descriptions under the designations "soapstones", "wen", "only chlorite" and "steatite". Origin The origin of talc is associated with metamorphism. In this case, both the processes of thermometamorphism and hydrothermal processes (hydrothermal-vein - when filling voids and hydrothermal-metasomatic when replacing) can be involved. Most often, talc occurs during hydrothermal alteration of ultramafic rocks after serpentinization. It is formed during metamorphism after dolomites and clays. Special properties: talc - acid-resistant; greasy to the touch; flexible but not stretchy. Place of Birth In Russia, the Shabrovskoye talc-magnesite and Miass talcite deposits in the Middle Urals are being developed; the Onotskoye deposit of steatite (solid) talc (Eastern Sayan); the West Baikal talcon-bearing province was identified. Large deposits are known abroad in Canada (Maidock), the USA (Gavernour), France (Luzenac), etc. Brumado, Bahia, Brazil - record crystals of talc (up to 4-5 cm!), covered with quartz // see. Min. Record: 1) 1987, 9, 204 2) 1992, 23, 274, 276 Talc is a common mineral found in Antarctica and the Mid-Ocean Ridge of the Atlantic Ocean; in Australia, Austria, Algeria, Argentina, Afghanistan, Bulgaria, Bolivia, Brazil, Burkina Faso, Bhutan, Great Britain, Hungary, Germany, Greenland, Greece, Zimbabwe, Indonesia, Iran, Spain, Italy, Kazakhstan, Cameroon, Canada, Colombia , both Koreas, Cuba, Madagascar, Mexico, Mongolia, Namibia, Norway, Oman, Pakistan, Paraguay, Peru, Poland, Portugal, Saudi Arabia, Slovakia, USA, Turkey, Chile, Switzerland, Sweden, South Africa, Japan and other countries . Practical value Talc is used for the manufacture of refractory materials, in metallurgy, in the textile, paper and chemical industries, and in medicine.
noble talc (transparent light talc),
Willemseit (nickel talc),
Minnesotaite (ferrous talc),
Steatite (wen) (dense massive talc)
Talc is a rock-forming mineral of talc schists and listvenites.
Steatite is used in the manufacture of various crafts. Powder prepared from talc or based on it has been widely used since ancient times and is still widely used as a powder for skin in medicine (a well-known baby powder is pure talc, but passed through the screening process of ferruginous rocks), as well as in everyday life to prevent sticking and friction of contacting surfaces ( in rubber gloves and other products, shoes, etc.). As a filler, it is used in rubber, paper, paint and varnish and other industries (in medical and perfumery and cosmetics). In ceramics (especially radio-insulating). Registered in the food industry as a food additive E553b. It is harmless and also not absorbed by the body. In a notorious "magical practice," talc was used to make potions that some believed could restore youth and beauty; these were various creams and ointments that acted on the skin as cosmetics, but nothing more.

What is talc? It is known to most people as a white powder that is widely used in cosmetics. The mineral has the ability to absorb moisture and oils well and have an astringent effect on human skin. It is an inert ingredient, i.e. does not enter into chemical reactions when it enters the body or on the skin. People have been using its positive properties since ancient Egypt.
Talc has the ability to absorb moisture and oils well and have an astringent effect on human skin.
Talc is a mineral widely distributed in nature and of great industrial importance. Also known as the softest mineral. What is talc and what is its chemical composition? It contains silicon, magnesium, oxygen and hydrogen. The talc formula is expressed as Mg3 Si4 O10 (OH)2.
Talc is a mineral widely distributed in nature and of great industrial importance.
Talc is a translucent mineral that is green, white, grey, brown or colorless. Sometimes there are other shades of stone, such as red or burgundy. It has a sheet structure, like mica. The sheets are held together only by van der Waltz bonds and easily slide relative to each other. Thanks to this, talc is the softest mineral. Feels greasy and soapy to the touch., which allows it to be used as a high-temperature lubricant (melting point is about 160ºС). When heated, it becomes more solid, has a weak electrical conductivity.
Most of the talc is produced in China, the USA and Japan. In Russia, the deposits are located in the Urals and Siberia. The quality of the mineral depends on the degree of whiteness of the crystals. During the extraction process, care is taken to avoid contamination by other species that may have a negative effect on the color of the product. Impurities are removed using the froth flotation method or by mechanical treatment. Mills produce crushing to the size required by customers.

Steatite is a type of talc
Talc is a constituent of many rocks. Steatite is a massive variety of metamorphic origin. Another name is soapstone. It has been mined for thousands of years. They made dishes from it that were not afraid of fire and slowly gave off heat. The rock consists mainly of talc with various amounts of other minerals (chlorite, magnesite). The color of steatite is gray, bluish, green, brown or variegated. Since its main component is talc, it has properties similar to it. This makes steatite a valuable material for many applications. Physical properties include:
- softness and ability to be easily cut;
- high density and lack of porosity;
- heat resistance and high thermal conductivity;
- ability to absorb moisture;
- resistance to alkalis and acids.
Mineral and chemical compositions are not permanent, which is why physical properties can vary in different minerals and even within the same rock. It depends on the starting material, temperature conditions and pressure.
Where is talc mined (video)
The level of metamorphism often determines the granularity of the steatite and its hardness.
The special properties of the rock allow steatite to be widely used in many areas:
- production of countertops and sinks;
- creation of decorative carvings;
- construction of stoves and fireplaces;
- making dishes;
- use as building and finishing material;
- molds for metal casting;
- production of marker pencils.
Due to its properties, steatite stone is used for medical purposes as a natural heating pad, as it can store heat for a long time.
