Crystalline minerals made up of mainly silica and alumina in combination with sodium and potassium oxides. Often considered a natural frit. Used extensively in both clay, up to 25% and glaze, up to 100%. G-200 HP - A high percentage potash spar, low in impurities, well suited for white glazes and porcelain clay bodies. G200HP is a high potassium aluminum silicate offering high potassium content and low iron oxide per unit of alumina. Typical analysis: SiO2 65.90% Al2O3 18.20% Na2O 1.52% K2O 13.20% CaO 0.75% MgO Trace Fe2O3 0.09% LOI 0.16% Melting Point 1100°C to 1300°C
