Abstract
A decorative porcelain enamel surface, preferably having the appearance of marble, is produced by first preparing the surface of an article, which may be irregular in configuration, for receiving a finished coat of porcelain enamel. A finished coat of porcelain enamel is applied on the prepared surface, and then by any of several novel steps the enamel is variegated to produce a marble appearance.
Claims1
An article having a decorative fused and vitrified porcelain enamel finish on a metal panel, said finish at least two layers comprising:
- a ground coat consisting of porcelain enamel paste in water having a first color applied to said metal panel over the entire surface thereof and fused by heating to fusing temperature and a porcelain enamel finish coat fused to said ground coat of a different color than said first color and distributed on said ground coat in randomly spaced areas to provide a variegated pattern resembling marble,
- said finish coat consisting of porcelain enamel paste in water and inorganic colorant unevenly distributed after fusing to produce a fired finish coating having areas of differing thicknesses over said ground coat to thereby provide a variegated pattern of non-uniform thickness.
