Soluble Salts are aqueous organic complexes of metal cations. These are used for decoration of polished or unpolished vitrified ceramic tiles. The technology facilitates decoration with pleasing colours and special effects. Being water soluble, softer shades can easily be obtained by diluting the solution with water.
Under controlled conditions, these salts penetrate vertically into the green tile body to a required depth. The colours develop during the combustion process of kiln firing under oxidizing condition. Since the colours penetrate to a predetermined depth, tiles can be polished without losing the decoration. Thus the process is capable for decorating polished, unpolished and rustic tiles with consistency/uniformity.

Most common method to apply soluble salts is by silk screen. The printing paste needs to have correct viscosity, which must be achieved by suitable additives. For reference, the additives are used in following proportion by weight of soluble salts. However exact proportion may vary depending on application, pH value and specific gravity of the salts. The paste should be allowed to age for at least 30 minutes, preferably one hour before printing.
