  • FIG. Shows a schematic sectional illustration of a Detail of a cooktop with a transparent, not colored Glass ceramic plate 1 as a cooking surface.
  • This glass ceramic plate 1 has at least one indicated by dashed lines Cooking zone 2, the hot area, on which an electrically operated radiant heating element 3 is assigned.
  • the hot area 2 typically has one Temperature of> approx. 350 ° C. It is surrounded by a dashed line indicated annular transition zone 4 with a thickness of 0 - 25 mm and the cold region 5, in which the temperature is usually below 220 ° C.
  • Layer 6 of temperature-resistant paints applied on the underside of the transparent glass ceramic plate 1 .
  • This layer 6 that can also be multi-layered, consists of colors or Color combinations, one depending on the area of the plate on which they are are applied, have adapted high temperature resistance and their Application to the underside of the plate is preferably carried out by printing.
  • the layer 6 consists of a layer section 6 a Colors made from organometallic solutions with metal and / or precious metal be formed. These are film-forming colors that one or several precious metals - especially platinum, palladium, gold and silver - as well further metallic compounds, dissolved in organic solvents, and / or contain metals colloidally, and to which substances such as resins, Cosolventien, and / or any additives are added, the color, Affect color intensity, adhesion or solubility of the luster colors. Manufacturers of such colors are e.g. Heraeus, Johnson Matthey, Cerdec. These colors are characterized by high color intensity at low Layer thickness and thus only affect the strength of the cooking surfaces slightly. Depending on the color, the temperature resistance is between 500 and 950 ° C in continuous operation and can with more temperature-resistant colors be briefly up to 1000 ° C.
  • the infrared transmission lies with simple printing - depending on the type of glass ceramic and the one used Pressure screen -, typically between 60 - 85%, resulting in heat transfer when cooking, especially when using bad dishes, contributes. This effect is supported by the fact that the material of the Glass ceramic plate 1 already has a very high IR transparency.
