Talc: Foliated talc that has a black color in massive form but cleaves into thin, flexible, inelastic and colorless sheets. Physical Properties of Talc Chemical Classification Silicate Chemical Composition Mg3Si4O10(OH)2 Crystal System Monoclinic Click to see full answer. Keeping this in view, how do you identify talc?Talc. Talc is the softest mineral, demonstrated by its position at the bottom of Mohs’ Scale of Hardness with a relative hardness value of 1. It has a soapy, greasy feel. Talc is formed by the hydrothermal alteration of ultrabasic rocks, or low grade thermal metamorphism of siliceous dolomites.Similarly, why is talc used in paint? Talc is used primarily in industrial paint and coatings, wood lacquers, printing inks, fillers as well as in various coatings. Talc increases coverage and weather resistance of the products. The use of talc creates a barrier effect, which limits the penetration of water and corrosive agents into paints and coatings. Keeping this in view, what are the main uses of talc? Ground talc is used as an ingredient in ceramics, paper, paint, roofing, plastics, cosmetics, talcum and baby powders, and a variety of other assorted uses such as making rubber and plastics.What is the specific gravity of talc?note: Specific Gravity of Talc =2.75 gm/cc.
