Halite

Chemical Formula: NaCl

Color: Any color, but is most often colorless or white

Hardness: 2-2.5

Importance: Halite itself is used to flavor foods, melt snow/ice on roads, and in many medicines. Also acts as a source of sodium and chlorine. Sodium from halite is used in glass making, paper manufacturing, and fertilizers. Chlorine from halite is used in plastics (PVC), water purification, especially in pools, and bleach. Chlorine is even used to bleach paper and make it white.

Other Interesting Information: Halite is usually found in enormous deposits where giant salt crystals are mined. Always forms in a rectangular or cubic shape, making it easy to identify.

My Take: Halite is one of the most common and basic minerals. In spite of this, it still has many unique properties and uses that makes it a special mineral.
