On sheet steel, a ground coat layer is applied to create adhesion.
White and colored second "cover" coats of enamel are applied over the fired ground coat.
The only surface preparation required for modern ground coats is degreasing of the steel with a mildly alkaline solution.
I beat out the large sculptural forms, the metal forming, fabrication, ground coats, compounding of enamels, spraying and burning of undercoats.
Other uses of cobalt are in electroplating, owing to its attractive appearance, hardness and resistance to oxidation, and as ground coats for porcelain enamels.
A ground coat is applied first; it usually contains smelted-in transition metal oxides such as cobalt, nickel, copper, manganese, and iron that facilitate adhesion to steel.
The frit in the ground coat contains smelted-in cobalt and/or nickel oxide as well as other transition metal oxides to catalyze the enamel-steel bonding reactions.
For electrostatic enamels, the colored enamel powder can be applied directly over a thin unfired ground coat "base coat" layer that is co-fired with the cover coat in a very efficient two-coat/one-fire process.
For ground coats, the composition of a frit for any given application is determined primarily by the metal used as the substrate: different varieties of steel, and different metals such as aluminium and copper, require different frit compositions to bond to them.
