In scientific terms, albite and microcline/orthoclase can form a solid solution. That is, an alkali feldspar can theoretically vary from 100% sodium to 100% potassium as its flux constituent. Soda feldspars actually tend to have at least 30% of their flux as potassium, while potash feldspars usually have at least 15% of their flux as sodium.

Potash Feldspar: Potash feldspar, or potassium feldspar, is another popular fluxing agent. It offers similar benefits to soda feldspar but has a slightly higher melting point due to its potassium ...

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.
