Talc

Notes. Talc is common and is the softest of all minerals (Mohs hardness of 1). Talc is also called steatite – or, in chemical terms, magnesium silicate hydrate. It is the main component of soapstone. Its crystals usually develop massive, leafy aggregates with laminar particles. Ground talc is called talcum.
