Fluorite is also used as a source of fluorine for hydrofluoric acid and fluorinated water. Fluorite, calcium fluoride is a major industrial mineral used as a flux in steel making as well as in the preparation of hydrofluoric acid and in the ceramics industry. Mainly used for glasses and enamels.
Fluorite's vitreous, cubic crystals (isometric system) and cleavable, granular masses have a wide color range (often green, blue, or purple) and may fluoresce under ultraviolet light. Hardness is 4, specific gravity 3.0-3.3. Fluorite deposits form under a wide variety of conditions: as veins produced by hydrothermal alteration, as beds and cavities in sedimentary rocks, in hot spring deposits, and in pegmatites.

Rock Gypsum is a sedimentary rock in the class known as chemical sedimentary rocks. It is formed by the evaporative deposition of gypsum from solution. It is commercially very important for the production of plaster of Paris and gypsum wallboard for house construction.

Halite Rock Samples. You get 10 specimens of the cool rock that we EAT everyday. Call 1-800-411-DINO (3466) for volume discounts.
Halite occurs in vast beds of sedimentary evaporite minerals that result from the drying up of enclosed lakes, playas, and seas. Halite is often used both residentially and municipally for managing ice.

Mica is a mineral name given to a group of minerals that are similar in their physical properties and chemical compositions. They are all silicate minerals, which means that chemically they all contain silica(SiO4). Mineralogists call micas sheet silicates because their molecules combine to form distinct layers. These layers can be seen in muscovite mica specimens because it can be split (mineralogists call this feature cleavage) into very thin, flexible, transparent layers. This physical property is so distinctive that all minerals that cleave in this fashion are said to have micaceous cleavage.
