Mica is the name given to a group of silicate minerals that have silicon and oxygen as their two major components. The Mica family of minerals includes several variations based on chemical composition and characteristics. Some common varieties are muscovite and biotite.They are made of hydrous potassium, aluminum silicate.

The most easily recognizable characteristic of mica are the thin crystal layers. With many micas the sheets peel off in thin transparent layers due to mica’s perfect cleavage.
Mica also has a brilliant shininess that glitters and sparkles. In fact the name mica is believed to have come from the Latin word micare which means “to shine.” Mica is responsible for the flashes of light in composite rocks such as granite, gneiss, and slate.
