French Champleve Porcelain And Enamel Vase

French Champleve Porcelain And Enamel Vase. Measures H 11 1/2" W 5" Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating. The word comes from the Latin vitreum, meaning "glass".Enamel can be used on metal, glass, ceramics, stone, or any material that will withstand the fusing temperature. In technical terms fired enamelware is an integrated layered composite of glass and another material (or more glass). The term "enamel" is most often restricted to work on metal, which is the subject of this article. Enamelled glass is also called "painted", and overglaze decoration to pottery is often called enamelling.

Enamelled glass is also called "painted", and overglaze decoration to pottery is often called enamelling. Champlevé is an enamelling technique in the decorative arts, or an object made by that process, in which troughs or cells are carved, etched, die struck, or cast into the surface of a metal object, and filled with vitreous enamel. The piece is then fired until the enamel fuses, and when cooled the surface of the object is polished. The uncarved portions of the original surface remain visible as a frame for the enamel designs; typically they are gilded in medieval work. The name comes from the French for "raised field", "field" meaning background, though the technique in practice lowers the area to be enamelled rather than raising the rest of the surface.
