Ground Silica is produced from our high-quality silica sand, which is ground into a very fine flour in size and consistency. Capital Sand’s strict operating standards when producing a highly consistent whole grain silica are also applied in producing our ground silica materials. Our ground silica can be used in the manufacturing of sanitary ware, glass making frit, ceramic tile, tableware, industrial ceramics, polishes, and home and industrial insulation. Delivery is available via truck, rail or barge.
