Enamelled glass sheets

Abstract

The present invention relates to a method of making a curved and / or tempered glass sheet that provides improved thermal comfort, comprising: (a) providing a glass sheet having an outer surface and an inner surface; (b) applying a thermal radiation reflective coating over at least a portion of the inner surface; (c) applying a black ceramic layer over at least a portion of the inner surface, the black ceramic layer covering at least a portion of the thermal radiation reflective coating and / or extending along the area covered by the thermal radiation reflective coating; and (d) hot bending and / or tempering the glass sheet. The black ceramic layer has a pattern to reduce the emissivity contrast in (d) between areas where the thermal radiation reflective coating is not covered by the black ceramic layer and areas where the black ceramic layer covers at least a portion of the thermal radiation reflective coating and / or extends along the area covered by the thermal radiation reflective coating.
