When QUARTZ is subjected to an electrical voltage, it oscillates at a certain frequency with high precision and at a very regular rate. For this characteristic, QUARTZ is used in the manufacturing of watches, telephones, computers, televisions and solar panels. QUARTZ is also used in the manufacturing of glass, glasses and lenses, the manufacturing of silica bricks, laboratory and industrial thermal crucibles as the ones used in iron melting furnaces, the manufacturing of Sodium Silicate, as well as in the manufacturing of paints, putty and rubber.
