Description

Technical Specifications and more details of Talc Powder are given below : Other Details: Talc is essentially a secondary mineral formed by the hydrothermal actions and regional metamorphism of magnesium rich rocks like dolomite, pyroxenite, amphibolite, serpentine, dunite and chlorite. In pulverized form it is whiter in appearance. The compact variety of talc is called steatite or soapstone. The word soapstone has been named probably due to its soapy feel. The impure and hard variety is called potstone, which is mainly utilized for making carvings, models, decorative vases, utensils, pots and the like and hence the name potstone.
