Soapstone (also known as steatite or soaprock) is a talc-schist, which is a type of metamorphic rock. It is largely composed of the mineral talc, thus is rich in magnesium. It is produced by dynamothermal metamorphism and metasomatism, which occur in the zones where tectonic plates are subducted, changing rocks by heat and pressure, with influx of fluids, but without melting. It has been a medium for carving for thousands of years.

Ancient Egyptian Scarab signet/amulets were most commonly made from glazed steatite.

Sodium silicate is a generic name for chemical compounds with the 
The anions are often polymeric. These compounds are generally colorless transparent solids or white powders, and soluble in water in various amounts.

Sodium nitrate is the chemical compound with the formula NaNO3. This alkali metal nitrate salt is also known as Chili saltpeter (because large deposits of this salt can be found in Chile) to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter.
