The Third Stage of Chinese bronze sculpture

This view would be too one-sided. We can look ahead as long as China's ancient history stained with the "king" of the edge, as long as the "king" of need, with the life of appliances, which one is not dumping all the energy of The Empress Dowager, and strive to become their stunning odd Jane, unless everything possible also in vain. Such a bronze sculpture was cast during the Shang and Zhou with or without lids. Fu Hao The reason why the rough bronze mirror, because life is not in its equipment, but had not yet reached the rule of bronze mirror technology requirements for such purity quality bronze alloy ratio, and so many problems.
As long as a problem is unclear, not resolved, apparently caused difficulties mirror the process of making bronze mirror image of the lack of good results, so the performance can not be gorgeous and so delicate ornamentation, in a few years later now, we have through science and technology bronze-to-business Zhou Qingqing test should have a correct answer. Some are very high and some of the china bronze sculpture is covered with elaborate patterns and shapes vary. List southern regions, the early Western Zhou Dynasty unearthed in Lishui Osan Fang Ding, including bronze 52.49%, 34.27% lead, tin, 0%; Dantu mother pier mid-Western Zhou Dynasty unearthed in Ge Lei pattern, with bronze 54.54%, 30.46% lead, tin 0%.
Unearthed in many parts of the country's green bronze block (Shang and Zhou dynasties for control of green bronze casting material) basic lead content of 30% -40% higher up to 50% less as tin, lead, and so is not high reasonable ratio, are likely to cause increased melting point of the rule of bronze, bronze liquid cooling rapidly, relatively smooth blocked, large thermal expansion and contraction, resulting in the decoration can not be cast to shape hair-thin precision effects, resulting in green bronze surface luster, bronze mirror image effect is directly affected by the constraints of high-lead bronze. The chinese bronze sculpture was made for pouring water. This results in "Business Week" unsatisfactory bronze mirror, bronze smelting material ratio and is the main problem. Early Chinese bronze mirror of the tin content than less, "regulating the family culture" bronze mirror only 1% of the tin content.
We are now seemingly simple the best ratio of lead and tin, which had the human from the "regulating the family culture" to a full exploration of the Spring and Autumn are nearly two thousand years. In this way, the bronze sculpture will become a set with pan. Until the Spring and Autumn really mastered the system required high-tin bronze mirrors, bronze containing about 65%, 25% tin, about 6% of lead, zinc and other trace metals of 1%. Mirror ratio of the required material completely different from the other bronze objects of bronze green material, is dedicated to a particular formula, coupled with repeated smelting, bronze mirror until the material in line with the clarity, degree of hardness and bright image. The sculpture in bronze has a spout to pour water. But unfortunately, mirror bronze material formulations to the Song also lost, and by the way the Song Dynasty bronze mirror used by the ratio formula, with bronze 65%, tin 10%, lead more than 20% zinc 7%, as if they resumed high-lead bronze, which is doomed to artistic quality of the Song Dynasty bronze mirror the rapid decline.
