Process Glazing & Enamelling
Used for decorative reasons as well as wear, heat, and corrosion protection. Enamelling achieves a compromise between the good properties of metals (strength) and those of glass (hardness, and chemical and temperature resistance.)

Enamels are special glass silicates (e.g. quartz, feldspar, alumina, zirconia, titanium oxide, etc.), which melt at about 1200 C.

The substrate is pre-treated and the basic glaze is applied followed by firing, dipping, and final firing. There are modern automatised techniques for high-series production (electrophoretic, electrostatic powder, or liquid enamelling.)
