Rock Crystal

White crystalline powder with low opacity.

Mountain crystal is a colorless, pure quartz. In impure form, quartz is found by-product of nearly all earth colors. Mountain crystal powder consists of crystalline white particles which are visible under the microscope. However, mountain crystal was used very rarely as filler, since its pulverization is very difficult. As a waste product in jewelry production though, small amounts of mountain crystal were always available for painting. In small quantitites, mountain crystal is found throughout the Alps. The mineral is known for its extraordinary transparency and brilliance. Both are lost when the grinding of the white crystalline powder is too fine. Mountain crystal received special attention in anthroposophic medicine and painting, and also in painting in the Himalayas. Since mountain crystal has both thermo luminescent and piezoelectric qualities, the positive effects often attributed to this popular healing stone (like physical and mental strength) may not be so far-fetched afterall.
