1.1 Glass-grade sand specifications The glass industry is the most important consumer of silica sand, although the mineral is consumed in many other sectors of the economy. Geochemical and granulometric industry specifications prescribed by Indian Bureau of Standards for silica sand for glass making is given in Table 1 & 2.

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 ...

There is not one specification for glass sand as a result of the many different types of glass that can be produced.
