Soapstone is a metamorphic rock. It is primarily made of talc, which gives its silky “soapy” feel. It also contains varying amounts of chlorite, magnetite, mica, tremolite, quartz, and iron compounds. Although soapstone is resistant to heat and acids, it is very easily cut with a knife which is a consideration when choosing a kitchen countertop material. Soapstone is gray or green with a smooth matte finish.
