Abstract
Process for the glazing of metal surfaces characterised in that it comprises the following stages: - applying at least one layer of adhesion-promoting enamel to the metal surface which is to be glazed, - raising the whole to the firing temperature of the enamel, - applying at least one layer of blue-coloured covering enamel, - heating the product to the firing temperature of this covering enamel in such a way as to distribute it uniformly over the surface, - applying at least one layer of enamel containing an oxide of the lanthanides group, - heating the whole in accordance with a thermal cycle having stepwise heating intervals with times and temperatures determined in such a way as to permit the formation of crystalline nuclei within the said layer of enamel, - applying at least one layer of transparent covering enamel, - raising to the firing temperature for that enamel.
