Mineral: FeldsparPrimary Commodity: FeldsparPrimary Commodity Uses: Feldspar is one of the most common minerals on the planet and is mostly used for glassmaking and ceramics.

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.   Glass and ceramics continued to be the major end uses of feldspar.
