What Is Potash? Essentially Potash is salt, in water-soluble form, that contains potassium. It is a term used in the fertilizer industry to refer to potassium chloride or potassium sulfate, nitrate, and oxide. Potash is the most common source of potassium used in the agriculture industry. Potassium is the K in N-P-K ratios in fertilizer.

In scientific terms, albite and microcline/orthoclase can form a solid solution. That is, an alkali feldspar can theoretically vary from sodium to 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.

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.
