what is feldspar used for

Potash Feldspar - digitalfire Potassium feldspar melts at around 1200C (higher than soda feldspar) producing a more a viscous melt than does sodium feldspar It can also produce a crystalline phase (leucite) that contributes to opacity Thus in industry potash feldspars are often used more for matte glazes while soda feldspar is used
