Understanding Ceramic Oxides
Al2O3 Aluminum oxide is supplied by kaolin and feldspar. It combines well with silica and basic oxides to give body, durability, and stability to glazes. It has a low expansion and high melting temperature. B2O3 Boric oxide is supplied by borax frits, gerstley borate, (or colemanite). It is a low temperature low expansion equivalent of silica.
