Division of Geology and Mineral Resources - Feldspar

Feldspar is one of the most abundant minerals in the earth''s crust. The feldspars include a range of compositions with a general chemical formula of xAl(Al,Si)3O8 where x can be sodium (Na) and/or calcium (Ca) and/or potassium (K). They are primarily used in glass and ceramics making. In glass, they improve hardness and durability.
