Abstract

Disclosed is a method of making a clear aqueous solution of sodium silicate from a mixture of silicon dioxide, sodium carbonate, and water. A melt is formed of the mixture of silicon dioxide and sodium carbonate, the melt is cooled to form solid sodium silicate, the solid sodium silicate is mixed with water and a sequestering agent to form a mixture that contains about 10 to about 2000 ppm of metallic impurities, and the mixture is heated under pressure to dissolve this sodium silicate in the water.
