The potash feldspar had a pyrometric cone equivalent of cone 9½, the soda feldspar, cone 6½, and the soda‐lime feldspar deformed at cone 11½. Reason to use potash feldspar is that it has a group of minerals containing potassium, sodium, calcium & aluminium silicates. Smaller quantities are used in the manufacturing of Tiles, Whiteware, and Sanitaryware. The rocks shown left to right are soda felspar, potash feldspar, nepheline syenite, and Cornwall stone. Soda feldspars melt at a higher temperature than the potash feldspars; however, the actual flow of the soda feldspar, once it begins, is more fluid and less viscous than its potash feldspar counterpart. Potash feldspars can usually substitute for each other in most glaze formulas without producing major changes in surface, provided the silica and alumina content are not too different. Both potash and soda melters create a glaze with low surface tension, which means they flow freely over the surface of the clay form. In ceramic bodies, the main vitrifying (fluxing) agent is feldspar. Glazes high in feldspar (35% or more) are plagued by crazing problems, yet still used by tens of thousands of potters. Feldspar as a mineral and classify feldspars as mainly as albite, microcline, orthoclase and anorthite. Potash Feldspar Lumps : 10-200 mm; Potash Feldspar is the main vitrifying Agent in ceramic bodies, The majority of white ware bodies contain good proportions of feldspar.
