  • Feldspar Distinctions, Characteristics & Identification

    Aug 10, 2019· Feldspars usually are white or nearly white, though they may be clear or light shades of orange or buff. They usually have a glassy luster. Feldspar is called a rockforming mineral, very common, and usually makes up a large part of the rock. In sum, any glassy mineral that's slightly softer than quartz is very likely considered a feldspar.
