Abstract: The invention relates to a process for the production of patterned lustre coatings on surfaces of bodies of glazed ceramic, in particular, tiles, glass or enamel using a cover corresponding to the pattern to be produced. On the surface of the body acting as substrate, a negative of the pattern is produced by a paste applied by screen printing, the body provided with the pattern negative is heated in a furnace to a temperature above approximately 400 DEG  C., the body is subsequently dipped into the solution of a metallic compound which reacts with the surface of the body not covered by screen printing to form a thin layer of the metal and oxides of the metal. In the metal/metal oxide layer of the body whose surface is cooled down by dipping, lustre colors are produced by heat input. Finally, after formation of the lustre colors, the screen printing paste constituting the pattern negative is removed from the body.
