Water-soluble salt colors are used in porcelain tile for surface decoration and in automated application systems (inkjet printing). Polyethylene glycol additive may be used to maintain viscosity and CMC gum for binding. In porcelain tiles these soluble salts penetrate into the surface and after subsequent polishing, the design appears.
CMC gum is indispensable for many types of ceramic glazes. It is a glue and is mainly used to slow drying and improve adhesion and dry hardness.
