The copper casting process of the enamel casting method describes that the copper casting process before the Shang Dynasty is the sputum casting method, that is, one-time casting molding. The law is divided into three aspects: alloy, casting, and molding.
1) The alloy is made by combining copper and tin according to the requirements of the copper engraving device, and is heated and melted into a bronze solution in a copper melting furnace for casting. There are different kinds of bronzes used in different alloys. For example, in the proportion of Wang Gou Jianjian, copper is 80% and tin is 20%.
2) Casting, the bronze solution is injected into the confluence from the gate. After the copper liquid is cooled, the inner and outer vanes are removed, and then polished and trimmed.
3) The standard is to make Tao Fan. The first copper sculpture is to use clay to make a model of the same size as the bronze sculpture to be cast. The ornamentation and the inscription should also be engraved on it at the same time, and then dried and baked to make it hard. Then turn over the outside, water and fine yarn, soil and chopped plant stems into mud, smear on the mud mold, after the mud is half dry, use a knife to divide into pieces to remove, dry and then roast hard, Become an outsider. The production of the inner fan is made by subtracting the thickness of the wall from the mud mold shape. If there is an inscription on the inner wall, the inscription must be reversed on the inner surface. After the dry roasting, the inner and outer modules are assembled together, tied with ropes, and then wrapped with thick mud, leaving the gate for casting copper liquid and the hole for discharging air inside the van. It is the shape of the bronze sculpture to be cast.
