The scientific name for soapstone is steatite.  It is composed mainly of talc, which gives it a "soapy" feel.  Soapstone has been used for aeons and in many cultures.  In fact, it is still a favorite carving medium.  Some of its uses are architectural features, counter tops, coasters, "surrounds" for stoves, sinks, tombstones, ceremonial carvings, bowls, goblets, cooking pots, boxes, vases, paving stones...  If I want to make something, I have a lot of choices.
