  Définition

  A water-soluble silicate of sodium (the simplest glass known) made by melting together sand and soda ash. In solid form it is hard and brittle, but when heated with steam, it becomes a colorless liquid with a wide range of viscosities according to water content. Silica gel is formed when the material is neutralized by addition of acid.

  Note :

  The major uses of water glass are as a dispersing agent for clay suspensions, as a fire-retardant coating for paper and fibreboard, as a binder for foundry cores, and as a detergent builder. A similar material is made from potassium silicate.
