Notes

(Richard Willis)

Mineral, of the ideal form K(AlSi₃O₈) with a typical empirical analysis of K₂O 16.93%, Al₂O₃ 18.36%, SiO₂ 64.72%
Hardness: 6 Density: 2.53-2.58 Soluble in HF and alkaline bases
Major potassium alumino-silicate in pegmatites, particularly in the vicinity of mica, plagioclase, and quartz rocks. Similar are the microclines and plagioclase.
