Feldspar

Feldspars are a group of rock-forming aluminium tectosilicate minerals, containing sodium, calcium, potassium or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth''s crust, and 41% of the Earth''s continental crust by weight.

What Makes Metamorphic Rocks So Unique?

 · Updated September 18, 2019. Metamorphic rocks are the third great class of rocks. They occur when sedimentary and igneous rocks become changed, or metamorphosed, by conditions underground. The four main agents that metamorphose rocks are heat, pressure, fluids, and strain. These agents can act and interact in an almost infinite variety of ways.

Feldspar

Feldspars of importance to ceramics are aluminosilicates of sodium, potassium, and calcium (Jones & Berard, 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) and anorthite (CaAl 2 Si 2 O 8).
