Enamel

Vitreous enamel is finely ground glass applied to a metal base and fused in a kiln at around 750-850 °C. The result is a glossy, hard layer with intense colors that do not fade, used for centuries in jewelry and metalwork.

• Techniques: cloisonné, champlevé, basse-taille, plique-à-jour and painted enamel.
• Durability: hard and glossy, but it can chip with a hard knock.

• Art jewelry with painted motifs.
• More affordable enameled copper pieces.
