The sand commonly used to make glass is comprised of small grains of quartz crystals, made up of molecules of silicon dioxide, which is also known as silica. When those molecules are heated to high enough temperatures, the sand melts and loses its crystalline structure, and as it cools it gains an entirely different structure.
So an alternative of this, manufactured sand is produced by the companies to meet the demands. The natural river sand is the product of sedimentation and this river sand contains more impurities than manufactured sand. So river sand sometimes cannot be used for important concreting works. So suitability of manufactured sand is tested.
