Patent ID: 8887531

Claim:
A method for producing a glass object in the form of a cooking appliance inner pane with improved thermal shock resistance, the glass object having a first side and an opposite second side and an edge bent in a pan shape, characterized by heating the glass object on the surface of the first side, wherein the heating takes place by means of a local heat source that travels across the first side of the glass object, starting from a surface temperature under the softening point until the viscosity reaches or goes below a first value of 10 (7.65±2) poise, characterized in that the glass object is heated with a temperature gradient perpendicular to the surface so that at least a part of the object under the heated surface remains at a temperature under the softening point, so that the thermal shock resistance of the glass object on the first side is increased, wherein the surface of the first side is not melted by the heating, and wherein the convex side of the pan-shaped glass pane is heated on the first side to improve the thermal shock resistance.
