Natural Silica Sand is naturally occurring sand with very high silica content. Good quality natural Silica Sand has negligible clay / impurities and is yellowish in colour as compared to quartz sand which is white in colour.
Silica is another name for silicon dioxide, SiO2, of which quartz is a specific latticed structure. So silica sand is quartz that over the years, through the work of water and wind, has been broken down into tiny granules. These granules can be used for many different purposes, and can be found in most non-tropical regions of the world.
