It occurs as foliated to fibrous masses, its monoclinic crystals being so rare as to be almost unknown. It is very soft, with a hardness of 1 (Talc is the softest of the Mohs' scale of mineral hardness, and can be easily scratched by a fingernail). It has a specific gravity of 2.5 Aca A 2.8, a clear or dusty luster, and is translucent to opaque. Its colour ranges from white to grey or green and it has a distinctly greasy feel. Its streak is white.

Micro biological : Nil Uses : The most commonly known application would be in cosmetics and dusting, body and baby powders, where the mineral helps to absorb natural oils, and the slippery nature presents a pleasant feel in warm conditions. It is also used in manufacturing face packs, mud packs etc. The paper industry is the largest consumer of talc, where it is used as a filler to enhance opacity and improve printing properties. It is also used as a pitch control agent in the production of wood pulp to remove resinous, sticky remains of wood, which otherwise would create dark or thin spots in the paper. In the ceramic industry, which is also a large consumer, talc prevents delayed glaze crazing, lowers firing temperatures, and reduces fired shrinkage. Ceramic wall tile contains up to 65percent talc in the formulation. Another important application is in paintand coatings. Talc improves exterior durability, controls viscosity, brushing, and gloss properties. It also reduces paint formulation costs, by extending or replacing more expensive resins and solvents. For manufacturing Plastics master batches and reinforcement it is widely used. In plastics, the mineral makes the resin more rigid and stronger. Polypropylene parts reinforced with as much as 40 percent of talc have replaced metal in many automotive applications, such as bumpers, interior plastic ductwork and fascias, as manufacturers have aimed to reduce weight, improve gasoline mileage, and reduce the number of separate parts that have to be made. It is also used as a filler in detergents & bath soaps due to its smooth and silky effect. It is also used in Rubber & Leather Industry as a heat absorbing agent Other uses of talc are as chewing gum dusting, insecticide carriers and as additive in asphalt roofing compounds.
