The bronze statue at this time doesn’t have any mysterious and majestic character

Because of strength, ductility increase, they reduce the chance of damage to copper bronze mirror, extend life; 3, tempering, colors are close to schungite, and "blue nearly white," it is appropriate for bronze mirror. See generally this Warring States, Han and Tang bronze mirrors fracture are as white as silver, as with this. Even the bronze sculpture shows the decorative nature. Visible copper bronze mirror after quenching maintains the state of tin, tin bronze original of some of the advantages, but also to improve the processing performance, extended life, is a very rational, scientific process. China's ancient bronze metal quenching is an outstanding technical achievement, it uses up so early, so wide, in the ancient world is rarely seen elsewhere. See from the lead content bronze cast bronze mirror month.

Ancient Chinese bronze mirror bronze alloy as ternary alloy, the alloy microstructure according to the physical and chemical properties, china bronze sculpture mirror for a certain kind of body cross-section geometry, the system regardless of the number of how many of its cast, a chemical should be used into the distribution ratio of the alloy; in a number of ancient bronze mirror of copper values in the chemical composition analysis can be seen from the early Warring States Period to the late Tang Dynasty bronze mirror in between the copper in a bronze mirror with two or more pieces of bronze species body with tin mirror are more stable, but its lead content is more or less the disparity. The bronze statue at this time doesn’t have any mysterious and majestic character. Fan cast through long-term use of replicated ancient bronze mirror discovered copper, alloys of lead content in accordance with climate change.

If only in accordance with a fixed value for the preparation of chemical analysis of copper alloy casting bronze mirror, will produce large amounts of waste. Ancient bronze mirror casting of copper, tin, lead chemical composition. In the long historical process of Bronze Age, the chinese bronze had always been the focus. Ancient Chinese bronze mirror of copper alloy, from the early Warring States Period to the end of the Tang Dynasty, has been using a high-tin bronze. According to many scholars at home and abroad, on this historical period bronze bronze mirrors made using a variety of scientific methods of chemical analysis showed that the vast majority of copper-tin bronze mirror of the content can be maintained at 23-25%, while there are high levels of lead and low; lead high up to 10%, while the lead actually lower than 1%.

I range through nearly two decades of cast bronze mirror casting method in practice that if we in the day of the bronze bronze mirror to copy, use the same amount of tin and lead are not the same the same cast two bronze bronze mirror, and the results will have a qualified, while the other one is bound to become obvious casting defects and waste. However, two basic varieties with the same size, but different lead content bronze bronze mirror to see, there is no obvious casting defects. The emergence of human patterns on the china bronze is of essential significance. Through long-term experiment that, only under different climatic conditions, cast bronze mirror, it may be this phenomenon. So, in the copper alloy, tin, lead alloy, respectively, in their play in what role? The percentage change in the alloy of copper and bronze mirror will produce what kind of quality and impact? This requires from copper, tin, lead to their sophisticated nature.
