Feldspar
Except for clay and silica, feldspar is the most common raw material in ceramics. It is also the most common mineral on the face of the earth—making up more than half the earth’s crust. Most feldspar has an almost perfect ratio of flux, alumina, and …
Feldspar - an overview | ScienceDirect Topics
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.

Feldspar - From Britain with Love
2021年7月15日 · Feldspar are passionate about preserving the skills and craft required to keep bone china production going in England, and to show that it is perfectly possible to make things from start to finish in the UK. Their Devon pottery now makes half of all their ceramics, and everything they make is hand painted there. Feldspar packaging
