Sand is a granular material composed of finely divided rock and mineral particles. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz.
Silica sand is the primary source of silicon dioxide that is essential in the manufacture of glass. To be suitable for producing glass, there must be a very high proportion of silica (above 95%) in the composition of the sand. That's why most sand deposits are not of sufficient purity for glassmaking. It's estimated that industrial sand ...
