A feldspar is typically referred to as potash if there is significantly more potassium than sodium typically there will be 2-5 Na2O. If the amounts are closer to equal, they are termed potash-soda feldspars or vice versa. Potash Feldspar is one of the most important materials for medium and high temperature ceramic glazes.
