Talc is a metamorphic mineral in solid form. The full scientific name is hydrated magnesium silicate, with the chemical formula is Mg3Si4O10(OH)2. In nature, talc is often found in a stone called steatite or soapstone (a high-talc rock), it is often combined with other minerals such as chloride and carbonate. Talc is usually blue, white, gray, brown or colorless.
