Cloisonné (景泰藍, also known as chā sī fà láng in Chinese, or 掐糸琺瑯) is a highly intricate and labor-intensive traditional craft technique. Techniques and Value of Cloisonné Manufacturing Techniques The production of cloisonné involves several complex processes and requires the manual skill of experienced artisans. Base Creation: First, a base for the vessel is made from metal such as copper. Wire Inlay (掐糸): Based on the design, very thin metal wires (often copper, silver, or gold) are attached to the surface of the base with adhesive to form the outlines of the pattern. Enamel Filling: Glassy enamel (enamel pigment) is filled within the frames formed by the metal wires. Firing and Polishing: The filled enamel is fired at high temperatures. Because the enamel shrinks during firing, this process is repeated many times, and the surface is polished until it is flat to complete the piece. High Technical Skill: Advanced craftsmanship and many years of experience are required for each process. Labor and Time: Because a lot of manual work and multiple firings and polishings are necessary, it takes a vast amount of time and effort to complete a single work.
