Silica sand is the main component when producing primary and specialty glass. Possessing a high level of Silicon Dioxide (SiO2), silica sand plays a key role in determining glass's color, strength, and clarity. Sand must be 98% silica to be considered pure, making silica sand a highly sought commodity among glass manufacturers.

Most glass is made by fusing a mixture of silica sand and soda ash, limestone dolomite and other material. Generally very high purity (CaCO3 98.5 % or CaO 55.2) is required for this application. Iron Industry: Limestone is used to remove impurities from molten iron. Limestone or lime is used as a flux to assist melting.
