Description
A pale blue naturally occuring mineral composed of Strontium sulfate. Celestite is found in sedimentary stone usually in conjunction with Halite and dolomitic limestone. Specimens have been found in England (Bristol), Italy (Sicily), Mexico (Matehuala) and the U.S.(Ohio, California). Celestite is mined as a source of strontium. It is also used in the manufature of ceramics, glass, and fireworks.
