Pyrophyllite, a mineral very similar to talc, is sometimes called soapstone in the generic sense, since its physical characteristics and industrial uses are similar, [3] and because it is also commonly used as a carving material. However, this mineral typically does not have such a soapy feel as soapstone.
Talc may be used in the processing of white rice as a buffing agent in the polishing stage. Due to its low shear strength, talc is one of the oldest known solid lubricants. Also, limited use is made of talc as a friction-reducing additive in lubricating oils. [20] Talc is widely used in the ceramics industry in both bodies and glazes.
Talc, or talcum, is a clay mineral composed of hydrated magnesium silicate, with the chemical formula Mg 3 Si 4 O 10 (OH) 2.
