Feldspar

Feldspars (KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8)are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight.

Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. In glassmaking, alumina from feldspar improves product hardness, durability, and resistance to chemical corrosion. In ceramics, the alkalis in feldspar (calcium oxide, potassium oxide, and sodium oxide) act as a flux, lowering the melting temperature of a mixture. Fluxes melt at an early stage in the firing process, forming a glassy matrix that bonds the other components of the system together.
