Mica

Mica is a naturally occurring mineral that is widely used in various industries due to its exceptional heat resistance, electrical insulating properties, and transparent nature. Mica occurs in a variety of forms, such as muscovite and biotite, and is known for its ability to flake into thin sheets. It is commonly used in cosmetics (such as highlighters, eye shadows, and foundations) due to its shimmering and reflective properties, as well as in paints, plastics, electrical insulation, and construction materials.
