Explanation

feldspathic glaze is a kind of high temperature glaze, usually with feldspar or minerals rich in feldspar as the main flux. The flux oxides in glaze are mainly K2O and Na2O, and their total amount is usually greater than or equal to the total amount of other alkaline oxides, but the total amount generally does not exceed 0.6 mole. The content of K2O is usually high in feldspathic glaze, while the content of alkaline oxide is low. This glaze is fired at temperatures above 1250 ° C. The characteristics of feldspar glaze include high viscosity under high temperature, strong glossiness, and a wide range of ripening temperatures. It usually appears slightly milky white, with a soft texture. This glaze is suitable for ceramics decoration, especially for hard porcelain, sanitary ware, electric porcelain and other products.
