The Uses of QuartzBecause of some of the properties of quartz it is used for many things. One of those proerties is that quartz is a very hard substance - harder than a steel file. Also most quartz dosent split eaisily. Glass can't transmit ultraviolet light, but quartz can. Quartz is piezoelectric meaning that when an electrical current passes throught them they vibrate a tiny bit. And when put under pressure quartz can generate a small electric charge by them-self.
Besides the industrial uses quartz can be used as jewelry and other gem uses. Crystalline quartz is the most common type of quartz. However, well-developed clear crystals are rare. Clear quartz crystals are called rock crystals. When they are cut as gemstones, they may sparkle as brightly as diamonds.
