When an aqueous solution of sodium silicate is treated with an acid, the mixture will become increasingly viscous and opalescent, and will finally set, it the silica concentration exceeds 2% and if the gel is not too acid or too alkaline. The time of set is determined by the pH, concentration of silica, concentration of certain foreign substances and the temperature.
