Strong and uniform adherence in white ground‐coat enamels can be promoted through special preparation of the enameling stock either through a plating operation or by deep etching the surface. The results obtained depend upon uniformity of the preparation of the base metal and the composition of the ground‐coat enamels used. It is necessary to compound the white ground‐coat enamel with considerable amounts of the accessory opacifiers in order to build up satisfactory opacity. Additions of opacifiers to the mill are also necessary. Fluidity of the enamel is important and should be high to decrease reboiling and to produce a smooth finish coat on etched stock. Addition of antimony trioxide to the raw batch of the enamel promotes adherence but develops reboiling.
