Mica can be cleaved to produce thin sheets which are somewhat flexible but mechanically stable.Depending on the raw material used and on the technical expertise of the cleaver, the sheets will be less or more suitable for optical applications.
mica Group of common rock-forming minerals characterized by a platy or flaky appearance. All contain aluminium, potassium and water; other metals, such as iron and magnesium, may be present. Micas have perfect basal cleavage. Common micas are muscovite and the biotite group.
Muscovite (mica schist), for instance, is pearlized, reflective and somewhat transparent. Schists are often used in jewelry and other types of artwork. Most schists are rarely used in buildings as the mica can split easily and they are not very strong.
A series or subgroup of the Mica Group. The CNMMN Subcommittee on Nomenclature of the Micas (1998, 1999) has recommended that the name biotite be used for a series between the joins Annite-Phlogopite and Siderophyllite-Eastonite, and is therefore no longer to be regarded as a species name. Fluorophlogopite and Fluorotetraferriphlogopite should be included.

Biotite Mica: Composition, Structure and Associated Minerals: Biotite is a n important and widely distributed rock-making mineral, but not as common as muscovite. It occurs in igneous rocks, especially those in which feldspar is prominent, such as granite and syenite. Found also in many felsite lavas and porphyries.

Its name is derived from "Muscovy Glass", which describes thick sheets of transparent mica that were once used as a glass substitute in Russia.
The mica minerals are distinguished by their perfect basal cleavage, which means that they are easily split into thin, often transparent, sheets. Two micas, biotite, and muscovite, are so common that they are considered rock-forming minerals. The rest are relatively uncommon, but phlogopite is the ...
Muscovite, commonly known as white mica, is a member of the mica family of minerals. The mica minerals all share the property of perfect basal cleavage, which means that layers of mica can be peeled off of a mica crystal in very thin sheets.
The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having nearly perfect basal cleavage.All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition.The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.
Muscovite is the most common mica, found in granites, pegmatites, gneisses, and schists, and as a contact metamorphic rock or as a secondary mineral resulting from the alteration of topaz, feldspar, kyanite, etc. In pegmatites, it is often found in immense sheets that are commercially valuable.
