This invention relates to a process for making enamels, more particularly white opaque enamels for sheet iron. Iron cannot be enameled directly, for. enamels are incapable of adhering to iron. In the production of such enamels, therefore, use is usually made of a base enamel containing oxides of cobalt, nickel, or the like which brings about adherence of the enamel to the iron. The enamel proper (coating enamel) also be produced on the enamel itself, such as more particularly on the adherence, on the elasticity, on the coeflicients of expansion and so forth.
The use of such alloyed metal sheets for the enameling consequently enables the production of opaque, more particularly white clouded, enamels even with a single'layer of enamel, i. e., without use of an enamel base, it being immaterial whether as clouding agents for such an
