CARBORUNDUM - Raven Crystals
ATTRIBUTES: Carborundum is a man made crystal also known as Silicon Carbide. In 1891, Edward Goodrich Acheson discovered Carborundum in an attempt to create diamond using electricity. Carborundum is composed of carbon and silicon atoms with strong bonds in a crystal lattice formation producing a very strong and hard material, insoluble in water or any solvent.

Silicon Carbide-Silicon Carbide Mnufacture and Supplier
Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive.
Silicon carbide, more commonly called carborundum, is extremely hard and is used in abrasives. Silica (SiO 2 ) in sand and minerals in clay is used to make concrete and bricks. Silica, as sand, is also the main constituent of glass.
