Soapstone is a metamorphic rock that consists of talc, steatite, magnesite, quartz, and other magnesium rich minerals and it is quarried like granite and marble. The talc found in soapstone is soft to the touch, which gives the smooth feeling of rubbing a piece of dry soap. Thus the name was derived – . Steatite is harder than talc, making it suitable for durable surface applications like countertops. Soapstone with a higher talc content is far softer and is often used for carving.

Soapstone (also known as steatite or soaprock) is a talc-schist, which is a type of metamorphic is composed largely of the magnesium rich mineral is produced by dynamothermal metamorphism and metasomatism, which occur in the zones where tectonic plates are subducted, changing rocks by heat and pressure, with influx of fluids, but without melting.
Steatite, also known as Soapstone, is a type of metamorphic rock largely composed of the mineral talc. Steatite is relatively soft because of its high talc content, which can vary by its different colors and grades.
The softer grades may feel similar to soap, hence the name, Soapstone. SOAPSTONE Soapstone, steatite, or talc schist is a metamorphic rock composed primarily of the mineral talc, in varying degrees of purity.
