* Sodium Silicate is produced by melting high purity sand with sodium carbonate (soda ash) in high temperature furnaces. The resulting product is a water soluble silicate powder that is known as water glass or sodium silicate solution once it is dissolved in water. Sodium silicate solution is chemically comprised of a weight ratio of silica to sodium oxide dissolved in water. Our sodium silicate has a weight ratio of 3.22 (SiO2:Na2O), which breaks down as ~28.7% silica (SiO2) to ~8.9% sodium oxide (Na2O), and that translates into a solution that is approximately 37.5% sodium silicate by weight in water.
