Talc is a mineral product composed of silica and magnesia. While this material is locally known as talc its chemical properties are substantially the same as asbestos, steatite and soap-stone. It has the greasy feeling of soap-stone and the fibrous properties of asbestos.
Foliated talc: Talc is a metamorphic mineral that frequently exhibits distinct foliation. Talc Mining and Processing Most talc in the United States is produced from an open pit mine where the rock is drilled, blasted, and partially crushed in the mining operation.
What is Talc? The term talc covers a wide range of natural rocks and minerals, most of which are magnesium silicates. The pure talc mineral is a hydrous magnesium silicate, Mg3Si3O10(OH)2, which theoretically is 31.7 percent MgO, 63.5 percent SiO2, and 4.8 percent H2O.
Talc is the softest mineral on the Mohs hardness scale at 1 and can be easily cut and crushed. Talc has perfect cleavage in one direction. This means that it breaks into thin sheets. As a result, it feels greasy to the touch (which is why talc is used as a lubricant).

Talc: Talc, common silicate mineral that is distinguished from almost all other minerals by its extreme softness. Its soapy or greasy feel accounts for the name soapstone given to compact aggregates of talc and other rock-forming minerals. Dense aggregates of high-purity talc are called steatite.
The Standard Industrial Classification (SIC) code for talc mining is 1499 (miscellaneous nonmetallic minerals, except fuels), and the SIC code for talc processing is 3295 (minerals and earths, ground or otherwise treated).
stated that a talc suitable for pharmaceutical purposes, used in cosmetic and toiletry products, contains at least 90% talc mineral and no detectable asbestos. Such stated compositional restrictions are not placed on indus trial grade talcs. One study demonstrated that a number of industrial talcs contained substantial quantities of tremolite, up to 87% by weight of the sample (Schulz and ...

Lassing talc was discovered in 1891 by the local landowner, Krennmoar, during construction work. He secured the mining rights. In 1901, the firm of Bischetsrieder & Gielow began underground extraction. In the mid-1920s, mining was suspended for a few years due to the bankruptcy of the owner. In 1939, the mine was acquired by the family firm of
