ABSTRACT:
The invention is related to a glass-ceramic article decorated with a ceramic baking finish. A SiO.sub.2 layer, about 20-200 nm thick, is placed between the decoration and the glass-ceramic material. The SiO.sub.2 layer can additionally contain, to match the refractive index to the refractive index of the glass-ceramic, up to 66.5 wt % of oxides which change the refractive index, in particular TiO.sub.2, ZrO.sub.2, SnO.sub.2, MgO or Al.sub.2 O.sub.3. In the process to produce the decorated glass ceramic article, the SiO.sub.2 layer is preferably produced according to the known sol-gel process. Preferably, an SiO.sub.2 gel layer, optionally precondensed by a brief thermal treatment, is produced on the still-vitreous article. The decoration is applied to this gel layer and afterward the vitreous article is subjected to ceramization. The SiO.sub.2 -gel layer is converted into an SiO.sub.2 layer, and the ceramic color of the decoration is baked-in. The SiO.sub.2 layer permits, above all, the production of substantially "halo"-free decorations with sharp contours.
