Potash Feldspar - digitalfire.com
Potash feldspars are often not as pure and white as soda spars. 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, ...
