The word "mica" is thought to be derived from the Latin word micare, meaning "to shine."
Based on the pillars of tourism and financial services, The Bahamas' economy has prospered since the 1950s.
Very fine-grained micas with typically greater variation in ion and water content are informally termed clay micas.
The arrangement of atoms in the different layers of mica can be described as follows.
Major sheet mica mining countries are India, Belgium, Germany, and China.
The flake mica comes from several sources: the metamorphic rock called schist as a byproduct of processing feldspar and kaolin resources, from placer deposits, and from pegmatites.
Scrap and flake mica is produced all over the world.
Until the early nineteenth century, large crystals of mica were quite rare and expensive because of the limited supply in Europe.
Micas are widely distributed and occur in igneous, metamorphic and sedimentary regimes.
Sheet mica is considerably less abundant than flake and scrap mica.

Throughout the ages, fine powders of mica have served various purposes, including decorative functions.
Mica was known to ancient Egyptian, Greek and Roman civilizations, as well as the Aztec civilization of the New World.
The presence of ions between layers of mica prevent swelling by blocking water molecules.

The mica group of minerals includes several closely related materials consisting of sheets of silicate tetrahedra and interconnected hexagonal rings.
Large crystals of mica used for various applications are typically mined from granitic pegmatites.
Micas have excellent chemical stability, high dielectric strength, and birefringence.
The sheetlike arrangement of atoms explains the nearly perfect basal cleavage of micas.
The earliest use of mica has been found in cave paintings created during the Upper Paleolithic period (40,000 to 10,000 B.C.E.).
