When we buy gold jewelry, we will look at 18K gold or 24K gold, in fact, it is the level of gold, and this K is the purity of gold. There is an idiom called "Gold is not a red, no one is perfect", the actual meaning of 100% pure gold does not exist. The same is true for bronze sculptures. The level of copper content will also play a big role in the quality of copper sculptures.
Bronze carving crafts are widely found all over the world, but the production process is not the same, the standard of copper content is not the same, of course, the effect is different. If the copper content of the whole bronze handicraft is too high or even 100%, it is not realistic. On the contrary, if the copper content is too low, various problems will occur, such as affecting the color of the finished product or the corrosion phenomenon.
At present, the level of bronze sculptures produced by China, the United States, Thailand and other countries is different, which is mainly reflected in the copper content and production process. Among the copper products made in the United States, the minimum copper content reached 90%, and some of the top sculptures even reached 98%. For us in these Asian countries, the copper content in bronze sculptures is about 55%.
Among the copper crafts with high purity of copper, they are highly resistant to oxidation, have excellent thermal conductivity, ductility and corrosion resistance. These superior properties make the whole crafts not corroded due to prolonged outdoor exposure. Of course, some patina will be produced, but it will not be too rusty.
Secondly, the level of copper content will have a certain impact on the color of bronze sculpture. In our country, pure copper is also known as copper. As the name implies, the whole copper is purple-red. It can be seen that the higher the copper content of the bronze sculpture, the brighter the color. However, due to the combination of copper with other alloys or chemicals, the color of the surface of the bronze handicrafts will change. Although this has achieved satisfactory results, this is not a long-term solution. It is easy to fade after a long time. .
Simu Bingding believes that everyone knows, "It's thick and elegant in style, magnificent in appearance, beautiful in appearance and high in casting process. It is also the largest bronze ritual of Shang Dynasty." After the measurement, the tripod has a high copper content. 84.77%, it is because of this, it will still be beautiful as it has been for so many years. When making crafts, cutting corners is not a long-term solution. Only real materials can create more perfect works.
