What is the required grain size of silica sand in float glass industry

In the glass industry, silica sand is a key ingredient in the production of glass products due to its high silica content, low impurities concentration (typically Fe2O3, Al2O3, TiO2) and physical properties. As such, glass sand generally has a higher purity and a more controlled grain size compared to regular silica sand.
