Six processes of making cloisonne

Cloisonne production is divided into six processes: tire treatment, silk cutting, blue dot, blue burning, polishing and gold plating. The first step, tire treatment, is to tap a copper tire bit by bit on the basis of red copper, and then draw copper wires of various shapes and sizes on it to make the tire shape.

The second process is called pinching silk, which is to curl the copper sheet into the lines you draw on the bottle and paste it with vegetable glue to form a certain three-dimensional space, that is, pinching silk enamel.

The third process is the blue dot process, which is to dot blue on the finished blue glaze. The main raw material of light blue glaze is metal copper, and the ratio of copper to cobalt is one to one, which is prepared according to a certain technological formula. You must use a blue tool made of copper tires to point blue. Insert the finely ground copper wire into the copper tire required for blue. Then tie the two ends of the copper wire tightly with thin iron wire to make it closely combined with the copper wire. Then scrape the blue glaze slurry from the blue glaze, evenly coat it on the copper wire surface, and compact it. And finally baking at high temperature.

The fourth process is to take out the blue works and burn them. If you don't burn it once, you have to burn it again and again. Controlling the temperature of the flame is the most important. The fifth process, grinding, is to put the burnt semi-finished product on the machine and rotate it at high speed, and grind it with grinding powder to grind the copper wire and color into a plane. The sixth process of gold plating is gold plating on the exposed position of the bottle mouth, so that the whole work looks very magnificent.
