Quick Summary

Soapstone is a soft stone composed primarily of talc, a silicate mineral. It is distinguished by its extreme softness, ranking lowest on the Mohs scale of hardness, and has a characteristic soapy or greasy feel, which gives it its name.12

Historically, soapstone has been used for carvings, ornaments, and utensils. Its resistance to heat and reagents makes it suitable for sinks and countertops. Talc, the main component of soapstone, is also utilized in lubricants, powders, and as a filler in various materials like ceramics, paint, paper, and plastics.1
