Feldspar
It is 5cpr5swidely used in the manufacture of glass products, in ceramics and other products . Feldspar is an important ingredient in the manufacture of glass. The raw material for glass consists of silica sand, soda ash (sodium carbonate) and limestone (calcium carbonate). Feldspar adds certain qualities to the process. Alumina provides hardness, workability, strength, and makes glass more resistant to chemicals. NaO2 and K2O from feldspar are fluxes. Fluxes reduce the melting temperature so less energy is used and decrease the amount of soda ash needed..
