Feldspar Statistics and Information | U.S. Geological Survey
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.

Generally, magmatic rocks with more silica (granitoids, pegmatites, greisens) usually contain K-feldspars and albite. Rocks with less silica contain Ca-rich plagioclase and the most Si depleted rocks contain mostly minerals from foids group like nepheline or haüyne. Pegmatites are definitely the most important feldspars source.
