Micas are a group of sheet silicate minerals distinguished by their perfect single cleavage. This cleavage allows mica minerals to be easily split into thin parallel sheets.Mica. 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.Gypsum occurs in two main varieties as white earthy masses or as clear crystals. In crystal form, its softness and single perfect cleavage with two less well-developed cleavage directions usually serve to distinguish gypsum from other similar-looking minerals. Anhydrite: When gypsum loses its water component, it forms the mineral anhydrite (CaSO4). Description Gypsum is a mineral found in crystal as well as masses called gypsum rock.

Radioactive material in building materials may add to indoor radon levels.Quartz, for instance, forms six-sided crystals, showing the hexagonal symmetry of its crystal lattice. There are two complicating factors to remember here: (1) minerals do not always form nice crystals when they grow, and (2) a crystal face is different from a cleavage surface. A crystal face forms during the growth of the mineral.Gypsum board is one of many gypsum panel products, defined in ASTM C11, Standard Terminology Relating to Gypsum and Related Building Materials and Systems, as “the general name for a family of sheet products consisting essentially of gypsum.”.
