Glass Production - National Industrial Sand Association

In the production of glass, there is both the need and requirement for silica to be chemically pure (composed of over 98% SiO2), of the appropriate diameter (a grain size of between 0.075 mm and 1.18 mm), and color (must contain between 0.025% and 0.04% Fe2O3). These requirements are extremely specific and technical; and this is because the ...
