Cloisonné enamel painting is a traditional art project in the fifth batch of representative projects of municipal intangible cultural heritage. Its manufacturing history can be traced back to the Yuan Dynasty. It was most popular during the Jingtai period of the Ming Dynasty. It is also known as "copper-based cloisonné enamel". It is an extension of the traditional cloisonné craft. It draws on the inlay and blue-dotting techniques of traditional cloisonné crafts. It uses metal wires to inlay various patterns on a flat medium, and uses glazes, glaze sands and other raw materials to dot blue and color. It integrates various arts and crafts techniques and is made by pure handwork. It uses alumina wire as the outline of the picture and natural quartz stone as the raw material, and then inlays various exquisite patterns.
