Glass Sand
Silica For Colored Glass
Silica sand is the primary raw material for Glass making. Kolayat Silica has high SiO2 content (>98.5%) and after washing and grading, impurities like carbonates are present only in trace amounts. This makes our sand quite suitable for container glass and coloured glass industry.
Higher oxides of Iron ( > 0.1%) make this sand unsuitable for clear glass without chemical processing.
