Potash Feldspar

Of course, real potash feldspars also have small amounts of CaO, MgO, Fe 2 O 3, etc. 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 ...
