Physical Properties. Mica is mostly brown, green, grey and red in colour, with a hardness of 2.5-4 and a specific gravity of 2.7-3.3. Mica is very flakeable and can be divided into very thin lamellae, transparent to translucent, with a glassy lustre. Mica has good heat resistance during heat treatment and can withstand high temperatures.
