Role of Silica Sand in the Glass Manufacturing Industry

 — What is Silica Sand? Silica sand, which can also be called industrial sand, white sand, or quartz sand, is mainly made up of oxygen and silica. In glass manufacturing, it can simply be called "sand" for making glass, since this is its main use. Sand must have at least 95% SiO2 and less than 0.6% iron oxide to be classified as silica sand.
