feldspar processing into glass

Feldspar in Glass Production - Feldspar from The Quartz Corp

Glass-making requires quartz and feldspar products that are free from contaminants, transparent, consistent in size, and low in iron. The QUARTZ Corp deposits have some of the lowest iron levels in the world. Our feldspar’s alumina content gives the finished glass products firmness, flexibility, cohesion, and chemical resistance.
