Historically, feldspar in ia was mined for use in the ceramics industry, for abrasives, and for gemstones (amazonite) (Pegau, 1932). Prior to 1907, according to Watson (1907) feldspar was mined primarily in connection with mica mining.
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.
