Mineral talc is composed of hydrated magnesium silicate with the chemical formula Mg3Si4O10(OH)2. Talc in powder form, often combined with cornstarch, is used as a baby backfill. Thickening and lubricating properties are provided by this mineral. It is part of ceramics, paints and roofing materials. It is the main component of many cosmetic preparations. It occurs as sheet-like to fibrous masses and in an exceptionally rare crystalline form. It has perfect basal cleavage and an uneven flat fracture and is foliated in a two-dimensional plate form. The hardness of Talc in the Mohs scale of hardness is 1 which defines that it is the softest mineral.
Talc is used in many industries, including paper, plastics, paints and coatings (e.g., for metal casting molds), rubber, food, electrical cables, pharmaceuticals, cosmetics, and ceramics. A coarse gray-green rock with a high talc content is talc or steatite, which is used for stoves, sinks, electrical cabinets, etc. It is often used on the surfaces of laboratory bench tops and electrical cabinets for its resistance to heat, electricity, and acids.
Talc is widely used in the ceramic industry in both bodies and glazes. Adds whiteness to low-fire art objects and increases thermal expansion to resist cracking. In earthenware, a small percentage of talc is used to perfuse the body and thereby improve strength and vitrification. It is a source of MgO flux in high-temperature glazes (to control the melting temperature). It is also used as a matting agent in earthenware glazes and can be used to produce magnesia mattes at high temperatures.
