ABSTRACT:
A method of producing luminous, wear-resistant decorations on ceramic or silicate bases is disclosed. A luster metal preparation or a precious metal preparation is first coated onto the base material. A decorative color preparation is then coated onto the luster metal or precious metal coated base. The decorative color preparation includes a mixture of a glass flux combined with mica platelets, wherein the mica platelets are provided with a thin coating of a metallic oxide. The metallic oxide may be light-impermeable or light permeable. The luster metal or precious metal coating may be stoved prior to the coating with the decorative color, or the luster metal or precious metal coating and the decorative coating may be stoved simultaneously. The stoving takes place at a temperature in the range of 500.degree. to 1100.degree. C. One alternative embodiment of the invention includes forming the luster or precious metal coatings and the decorative color preparations on a decal release paper, and then transferring the decal to the base. Another alternative embodiment includes coating with the decorative color preparation before coating with the luster or precious metal.
