Abstract: A multi-layer glass enamel is disclosed. The various layers of the enamel are included to provide certain performance characteristics to the enamel. The components of each layer can be individually adjusted to tailor the performance characteristics influenced by that layer without changing the influence of the remaining layers.

Abstract: The present subject matter provides for a multi-layer conductive trace. The trace can be formed by digital printing the individual layers and firing. The individual layers each impart functional characteristics to the conductive trace and each layer has components that can be adjusted to affect the performance characteristics of that particular layer without detrimentally affecting the performance characteristics of the remaining layers.

Abstract: Ceramic decoration coloring substances substantially containing a zirconium pigment of the host lattice or inclusion type and a glass flux at a pigment volume concentration (PVC) of at least 30% have an increased color saturation C* if the glass flux comprises at least 71 wt. % PbO. Preferred decoration coloring substances have a PVC in the range from 40 to 70% and a PbO content of 75 to 85 wt. %. The decoration coloring substances are especially suitable for production of decorations, burned at 1000 to 1250°C, with increased color saturation C*.

Abstract: The resistance of tableware decorations to cutlery scratches can be improved by using a decoration coloring substance whose coloring component is a molecular sieve charged with a metal selected from V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ag, Au, Ru, Rh, Pd, Os, Ir, Pt and/or an ion or a compound of the metal. The coloring component is preferably an aluminosilicate or silicalite charged with Au, Pt, Pd or Cu.

Inclusion pigments based on heavy-metal sulfides and selenides in an oxidic or silicate casing, especially ZrSiO.sub.4, result in more color-stable decorations in a porcelain firing if color-stabilizing auxiliary agents from the series of Zn compounds, especially ZnO or zinc-containing glass frits, or cerium(III) or cerium(IV) compounds, especially CeO.sub.2, are used in the decorative layer and/or glaze layer as color-stabilizing auxiliary agents. The amount used in the decorative layer is generally 5 to 50% by weight in the case of ZnO and CeO.sub.2, relative to the inclusion pigment. The pigment composition contains at least one of the color-stabilizing auxiliary agents in addition to an inclusion pigment.
