  • Glass-ceramic article decorated with ceramic colorings and method for making the same
    Patent number: 5716712
    Abstract: A glass-ceramic article decorated with ceramic colorings has a first coloration layer over which at least a second coloration layer is arranged. The second coloration layer at least partially overlaps the first coloration layer. The first coloration layer can be applied as a base decor over a large area and be finely distributed on the surface of the glass-ceramic article. The base decor, for example, also protects the surface of the glass-ceramic article against scratches. The second coloration layer is colored differently and, as a marking decor, defines, for example, the cooking zones and facilitates the confusion-free recognition of the thereby individualized color function areas.
