Baryte or barite (BaSO4) is a mineral consisting of Barium Sulfate. The Baryte group consists of baryte, celestine, anglesite and anhydrite. Baryte itself is generally white or colorless, though may sometimes be yellow or gray. Baryte is the main source of barium. Baryte and celestine form a solid solution (Ba, Sr)S)4.
The radiating form, sometimes referred to as Bologna Stone, attained some notoriety among alchemists for the phosphorescent specimens found in the 17th Century near Bologna by Vincenzo Casciarolo.
Baryte sometimes can be found in lumps and sometimes in sandstones, which are called “desert rose” similar to a rose in shape can be found. These forms of Bayte can be colorless, or white, yellow, brown, blue, green or red. In Mus, Turkey there is a rich source of Baryte.
The name Baryte is derived from the Greek work βαρύς (heavy). It lists a 3-3.5 on Mohs hardness scale. Crystal system is Orthorhombic, specific gravity 4.3-5, refrective index is 1.63.
