Feldspar mining in North America may have begun in pre-Colonial times. Examination of shards from a large number of prehistoric culture centers, widely distributed in both place and time, shows that native potters often depended on feldspar from feldspathic sands to provide the temper (increased hardening) for their clay pots.

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.
