This is formed by deposits of talc combined with other minerals by a process called metamorphosis. Soap stone also contains minerals magnetite, dolomite, mica, quartz, tremolite and chlorite other than talc.
Craftsmen began sculpting sculptures out of soapstone and they also used the same mineral to create household articles and mainly kitchen utensils. In India the use of soapstone utensils is known even before 3rd century B.C. and are still used for religious purposes in temples and houses.
