Notes

F-20 Feldspar is a high quality sodium/ Potassium/calcium aluminum silicate used principally as a flux for ceramic applications. Carefully beneficiated using the froth flotation process, F-20 Feldspar offers high levels of alkali oxides per unit of alumina with low iron oxide content.

Suitable for all types of glazes
Max Firing Temp: over 1250C
