Quartz is used to manufacture glass, ceramics, as a building stone (in sandstone), and other manufacturing processes. It is the second most abundant material in the Earth's crust. It can have a natural vibration frequency, and this property is exploited to in watches, clocks, radios, television and various communications devices. It can also have piezoelectric property making it useful for certain types of electronic devices including phonographs.
