The technique of enameling
Enameling is one of the best means of protection against metal oxidation. Furthermore, it bestows a bright surface and sharp, indelible colors on the objects it protects.
At the outset of the enameling process, we use glass by-products (quartz and alumina) stained with metal oxide and melted down at high temperature to obtain a powder or ceramic slip.
the metal is surfaced with the powder or the slip depending on procedures (soaking, coating, electrophoresis), then comes the drying, and at last the firing in a oven at 1,454º F.
The harmonious bond that is then realized combines metal resistance with glass protection.
