Ceramics Chpt. 1
Silicates are compounds made of silica and melters. Ceramists use two two silicates-- talc and wollastonite.
Ground silica is derived from ground quartz. It is used in ceramic recipes when additions of pure silica are desired.
Fluxes contain no silica, and are composed of only elements that modify the melting.
