Sodium silicate (Na₂SiO₃), or "water glass," is a versatile compound in ceramics. Primarily used as a deflocculant in clay slips and casting slurries, it reduces viscosity by dispersing particles, improving workability. It also acts as a binder in glazes and engobes, enhancing adhesion and green strength.

Sodium metasilicate pentahydrate is a non-toxic, odorless white powder that dissolves in water but not in alcohol or acid. Its alkaline solution possesses descaling, emulsifying, dispersing, moistening, and buffering properties. It serves as a diluting agent in ceramics, providing good fluidity, high purity, and effective degumming.
