Feldspar Processing | Equipment, Flow, Cases
Uses: Feldspar is used to make dinnerware and bathroom and building tiles. In ceramics and glass production, feldspar is used as a flux. Flux is a material that lowers the melting temperature of another material, in this case, glass. Feldspar can be replaced by other minerals and mineral mixtures of similar physical properties.

Feldspars are aluminosilicates containing varying amounts of calcium, potassium, or sodium. In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase.
