Talc is a hydrothermally altered mineral. Magnesium-rich minerals often become talc through hydrothermal alteration, so talc often presents mineral illusions such as olivine, refractory pyroxene, amphibole, tremolite. Talc is a common silicate mineral. It is very soft has a smooth feel. People have chosen ten minerals to represent ten hardness levels, called Mohs hardness. Among these 10 levels, one (that is, the softest one) is talc. Soft talc can replace chalk to make white marks. Talc is generally lumpy, leafy, fibrous, radial, is white off-white in color. It may have various colors due to other impurities. There are many uses for talc, such as refractory materials, paper making, rubber fillers, pesticide absorbents, leather coatings, cosmetic materials, carving materials. Liaoning Talc Powder

Talc is a trioctahedral mineral with a structural formula of (Mg6) [Si8] O20 (OH) 4. Talc is generally lumpy, leafy, fibrous, radial, with a very soft texture a smooth feel. There are many uses for talc, such as refractory materials, paper making, rubber fillers, insulation materials, lubricants, pesticide absorbents, leather coatings, cosmetic materials carving materials. Talc is the softest known mineral can leave scratches on talc with your nails.
