The term water glass describes water-soluble alkali silicates that have been solidified from a melt. For this purpose a batch consisting of ultra-pure silica sand and potassium carbonate or—depending on the application—sodium carbonate with CO2 formation is melted and, after cooling down, is milled into a powder. The powder is then used as a clear, alkaline solution or as a gelatinous to firm compound in a multitude of processes and products. Water glass is valued and proven in prosthetic dentistry as a cementing agent in the manufacture of investments, in foundries as a binding agent for sand moulds and for various applications in the construction industry. It is also very popular as an adhesive and bleaching agent in the paper industry and as an additive in detergents.
