Patent

CA 2483339

The method of making a knobbed glass or glass ceramic plate includes placing a glass or glass ceramic plate on a support having knob-shaped elevations and/or depressions; jointly heating the plate and the support over a transformation temperature of the glass or glass ceramic plate and, advantageously after a certain time interval, subsequently cooling the plate to room temperature. The glass or glass ceramic plate with knobs made by the method is also part of the invention. The glass or glass ceramic plate with the knobs can be used in heating units, such as baking ovens, for thermal isolation or decoupling of differently heater spatial regions. Also it can be provided with a germ killing coating for use in an air conditioning unit to clean air.
