Talking about the casting technology of copper tripod

Do you want to know the casting technology of Tongding? Let's learn together with China Copper Sculpture Industry Network!
The Shang Dynasty bronzes are all cast by the same method, and the number of the van is determined by the shape of the device. In the early Shang Dynasty, the bronze prince was cast by two pieces of belly, one piece of metric, one piece of bottom and one core, while the copper dynasty of the late Shang Dynasty used 16 pieces. In the middle of the Shang Dynasty, in addition to being able to cast large objects, it has been possible to pre-cast some of the accessories of the objects by means of split casting, and then cast them together with the main parts.
The late casting technology of the Shang Dynasty has further development. For example, the body of the mother-in-law and the four-legged are integrally cast, and the Ding ear is molded, turned, and cast on the body. According to its volume and weight estimation, when the required metal material is more than 1000 kg, a large copper melting furnace must be used for smelting, and it is possible to use the method of casting through the ground tank.
In the late Shang Dynasty, the technology of copper inlaid jade was also developed. For example, the jade aid copper that was unearthed from the Tomb of Women’s Tomb was cast into Tao Fan, which was included in the copper. Iron blade matte found in the city of Yucheng and other places was also cast using this technique. Inscriptions have not been seen on the bronzes of the early and mid-industry of the inscriptions.
