Silica sand is the primary raw material for making glass and allied products. Kolayat-origin silica has high SiO2 content (>98.5%) and the processes of washing and grading leave only a negligible amount of impurities like carbonates. This makes our sand most-appropriate for container glass and coloured glass industry.
Higher oxides of iron (> 0.1%) make this sand unsuitable for clear glass without chemical processing.
