Talc / Soapstone also known as Steatite Powder in pulverized form is whiter in appearance. We offer Talc in varying fineness, from 200 Mesh to size of 700 Mesh. Talc / Soapstone is used as a filler in paper, rubber, textile, paints, face and talcum powder, soap, fireproof roofing, foundry facings, lubricants, linoleum and oilcloth, electrical insulation, and pottery.
Soapstone is primarily composed of talc. It shares many physical properties with that mineral and make it valuable for many different uses. It is non-porous, heat resistant, non-absorbent, soft and easy to carve, high specific heat capacity and resistant to acids and alkalis.
The mineral composition in this rock can vary. It depends upon the parent rock material and pressure/temperature conditions of its metamorphic environment.
As early as 8,000 years ago, Native Americans used the rock to make carved sculptures and cooking bowls. In the Late Archaic Period, Native Americans from North America made bowls, smoking pipes, cooking slabs and ornaments.
