G-40 is a potassium / sodium / calcium aluminum silicate used as a source of alumina and potash in specialized glass batch formulations requiring higher potassium levels. Carefully beneficiated using the froth flotation process, G-40 Feldspar offers low iron oxide and high alkali oxide content per unit of alumina.
