Potash Feldspar - Digitalfire

Notes. One of the most important materials for medium and high temperature ceramic glazes. 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).
