A feldspar is typically referred to as 'potash' if there is significantly more potassium than sodium (typically there will be 2-5% Na 2 O). If the amounts are closer to equal they are termed potash-soda feldspars (or vice versa). Of course, real potash feldspars also have small amounts of CaO, MgO, Fe 2 O 3, etc.

Sodium Feldspar also know as Soda Feldspar is generally a clean white mineral that sources sodium, alumina and silica along with some potassium and calcium. No actual materials have the ideal formula shown here, they all have some K 2 O and small amounts of other contaminants. Sodium 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

The dissolution of two finely ground potassium feldspar rocks (KFR). from Malawi and Sri Lanka, was examined in four indigenous acid soils using open‐leaching and closed‐incubation systems. Increases in fractions of soil potassium (K), compared to the control, indicated that the extent of dissolution of KFR was usually substantially ...

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
