Quartz

Quartz is a hard, crystalline mineral composed of silicon and oxygen atoms (silica dioxide). It is one of the most abundantly available minerals and is resistant to both chemical and physical weathering. Quartz in its purest form is clear or white in colour but different impurities within the atomic lattice can cause the colour to change. Due to its abundance, crystalline nature, high thermal and chemical properties, quartz is employed in various applications in the glass industry, construction industry, metallurgical industries and numerous other industries.
