Quartz is consisting of highpurity silica in amorphous (noncrystalline) form. Quartz is a very common mineral in the Earth crust. It has been proved that quartz is the second most widely available mineral on the continental crust of the Earth, covering almost of it, beaten only by feldspar. Chemically, quartz is silica, or silicon dioxide, SiO2.
