Physical properties
Hardness of 6 on the Mohs scale, pink to salmon-red color, vitreous to pearly luster, monoclinic or triclinic crystal system, and two directions of good cleavage intersecting near 90 degrees.
Formation & geological history
Formed through the crystallization of magma in igneous environments like granites and pegmatites, or through high-grade metamorphic processes.
Uses & applications
Used primarily in the manufacturing of ceramics, porcelain, glass, and as a scouring agent in abrasives.
Geological facts
Potassium feldspar is one of the most abundant rock-forming minerals in the Earth's crust, often giving granites their distinct pinkish hue.
Field identification & locations
Easily identified by its characteristic salmon-pink color and right-angle cleavage planes, found globally in pegmatites and granitic terrains.
