Definitions

  • the invention relates to tanning dishes for microwave ovens made of ceramic, glass or glass ceramic, which is provided with a metal coating.
  • tanning dishes When cooking in a microwave oven, the surface of the food remains unchanged. So-called tanning dishes are therefore used to produce a tanning crust.
  • This tableware made of glass, ceramic or glass ceramic is preferably provided on the bottom with a special metal alloy that absorbs the microwaves and thus becomes hot in the microwave oven. This additional heating makes the food crispy and brown.
  • the metal layers previously used for tanning dishes have the disadvantage that they still reflect a considerable proportion of the microwave energy and therefore do not convert into heat energy.
  • This object was achieved in that first a layer of a metal-containing glaze and then a layer of a metal-free glaze is applied to the dishes.
  • the metal-containing layer is preferably composed of 60 to 85% by weight of copper, aluminum, iron, nickel, tin, zinc or their alloys in powder form and 15 to 40% by weight of a glaze 3 to 15% by weight of alkali oxide 5 to 20% by weight of aluminum oxide 5 to 30% by weight boron oxide 40 to 70 wt.% Silicon oxide 0 to 10% by weight of alkaline earth oxide 0 to 20 wt% zinc oxide 0 to 15 wt% titanium oxide 0 to 40% by weight of zirconium oxide 0 to 10% by weight of tin oxide and 0 to 5 wt% fluoride.
  • the same glaze as the metal-containing layer is advantageously used for the metal-free protective layer.
  • the glass frits are selected so that they have an optimal match in terms of the coefficient of thermal expansion between 20 and 300 ° C with the ceramic, glass or glass ceramic underlay.
  • the layers can be applied and baked onto the tanning dishes using known techniques, such as screen printing, offset printing or using decals.
  • a layer of a paste is first applied by screen printing, which contains 75 wt.% Zinc powder and 25 wt.% Of a glass frit consisting of 48.1% SiO2, 19.4% B2O3, 9.9% Al2O3 , 6.6% ZnO, 5.3% Li2O, 2.0% ZrO2, 5.0% BaO, 1.9% F2, 0.7% MgO, 0.6% Na2O and 0.5% TiO2.
  • the applied layer is baked in air at 780 ° C (about 10 minutes) and then the same glass frit is also printed on the baked layer without metal powder addition and then baked (780 ° C) using screen printing.
  • 780 ° C about 10 minutes
  • 780 ° C 780 ° C
  • screen printing In a microwave oven you measure a temperature of 290 to 300 ° C in this bowl after 3 minutes, which is sufficient to brown food.
