Feldspar
Potassium and sodium feldspar for ceramics, tiles, glass, and glazes.
Applications
Feldspar serves as a primary flux in ceramic and tile bodies, lowering firing temperature and improving vitrification, surface finish, and mechanical strength. In glass manufacturing it raises melting efficiency, clarity, and chemical resistance across flat, container, and specialty glass. It also performs in glazes and enamels and as a functional filler in paints, plastics, and refractory formulations.
