Apart from the different enamels one can use there are different techniques of application;
Sgraffito – Where one can scratch through a layer of freshly laid enamel to a pre-fired enamel surface.
Basse-Taille – Where the metal beneath the enamel surface has been textured in some way with a transparent enamel on the surface.
Champleve – Where areas of metal are removed and filled with enamel, fired and ground back to a smooth surface, then re-fired to revive the gloss of the enamel.
Limoges – Where extremely finely ground enamel is painted on a pre-fired surface with successive applications and firings of very fine layers to build up the design.
Cloisonee – Where fine wires form “cells” and very thin layers of enamel are placed within the cells and fired. After 4 to 5 layers the enamel is ground down to a smooth surface with the wires showing. A final firing will restore the sheen of the enamel.
Plique a Jour – Where transparent enamel is used as stained glass. The enamel is suspended within a frame and light passes through to show the beauty of the jewell colours because there is no base metal, only the fame.
