Overglaze colours are colours that are applied over the glaze coating, so they are sometimes known as 3rd firing colours-the first firing bing the biscuit firing, the 2nd firing being the firing of the glaze. Decorative designs can be applied on glazed bodies, such as tableware or tiles by hand painting, by decals or transfer of predesigned patterns onto the glazed body, or by direct printing on the body of the required patterns.
Whatever the method of application, the overglaze colours (high temperature stable pigments, pre mixed with fluxes for the required temperatures) are required.
For glass decoration, fluxes fusing at **0deg.C or **0 deg. C are required.
For metal enameling( sheet steel, cast iron, copper or jewelry), fluxes fusing at **0 deg. C are used.
For bone china, hotel china, tiles and sanitaryware also fluxes fusing at **0 deg. C are usually used, though sometimes, fluxes fusing at ***0 deg. C are preffered.
Decal manufacturers and ceramic printers usually prefer fluxes fusing at **0 deg. C.
