Quartz Powder

Quartz is chemically silicon dioxide (SiO2) thus containing 46.74% Silicon and 53.26% oxygen by weight. It is the most abundant mineral on the Earth. It is found in almost every geological environment and also it is at least a component of almost every rock type.

Quartz is mostly crystalline in its arrangement though it may vary in the extent of crystallization. The macro-crystalline variety is the one in which the individual crystal is visible to the unaided eye. The other variety is micro-crystalline or cryptocrystalline, in which aggregates of crystals are visible only under high magnification. The transparent variety tends to be macro-crystalline and the cryptocrystalline varieties are either translucent or mostly opaque.

The same molecular structure, if amorphous in arrangement is very different in properties and is thus termed as glass not quartz.

Color: It is clear in pure form.

Lustre: It is vitreous, waxy and dull.

Streak: It is white.

Diaphaneity: It is transparent.
