Feldspars are aluminosilies 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.
Apr 12, 2016 · Its specific gravity is almost identical to quartz and feldspar, thus ruling out the possibility of gravity separation methods. Beryl is harder than quartz. Most of the production of this mineral in the past has been by hand sorting and cobbing of high grade crystals from pegmatite mining operations.
· Another diagnostic feature is the feldspars colour range. In this case, the colour typically ranges from white to gray.
