Feldspar an overview ScienceDirect Topics
Feldspars of importance to ceramics are aluminosilicates of sodium, potassium, and calcium (JonesBerard, 1993) They are used as fluxes to form a glassy phase in bodies, thus promoting vitrification and translucency.They also serve as a source of alkalis and alumina in glazes. The pure spars are albite (NaAlSi 3 O 8), orthoclase or microcline (KAlSi 3 O 8)
