Cloisonné
Enamel decoration technique using metal partitions

Cloisonné is an ancient and refined technique in which an image is created from metal partitions filled with bright enamel. The method involves soldering thin wire contours of a design onto a metal plate, and filling the resulting cells with a colorful glass-like mass. After firing and polishing, the piece sparkles like a precious stone.
This technique originated in Byzantium and was widely developed in China during the Ming Dynasty. Europeans, encountering oriental vases, marveled at their 'frozen light.' Cloisonné was used to decorate icons, goblets, snuff boxes, and jewelry.
The distinctive feature lies in filigree precision — each partition creates a clear contour, and the color palette resembles a miniature in glass.
