'''Quartz''' is the second most common [[mineral]] found on [[earth]]. More accurately, silicon dioxide, quartz has a chemical composition of SiO<sub>2</sub> arranged in a repeating lattice forming [[crystal]]s. Pure quartz is clear, but colored variations are created because of impurities in the crystal.
<br> Quartz is used in a number of applications such as [[glass]] making, optical lenses, abrasives, in electrical components or decorative gemstones or other stones.
