    Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.

    Mica is a naturally occurring, highly lamellar phyllosilicate of aluminium and potassium that exhibits an almost perfect basal cleavage. This means that mica particles can be easily split into thin, often transparent sheets. Amongst platy minerals, micas are unique due to the broad range of particle sizes naturally available, from microns up to several centimeters. Mica is often referred to as ‘glimmer’, a
