First, "Zhou Li? One of the exam notes? Liu Qi?
Eugene: Here? Kim. There are two kinds of sayings: one refers to bronze and the other refers to pure copper. What about here? Qi? What about the dose? Agent? Generally refers to the amount of copper and tin.
Its gold and tin are divided into one, that is, the gas of Zhong Ding;
Its gold and tin are divided into one, that is, the axe Jin Qi;
Its gold and tin are divided into one, that is, the gas of Geji;
Two-thirds of its gold and tin are in one place, which is called the gas of the big blade;
Its gold and tin are in the second place, that is, the arrow is cut and killed;
Half of Suk Kim, it is called as a mirror. ?
This is a record of the known bronze alloy configuration technology in the pre-Qin period. According to Guo Moruo's textual research, this should be the official book of Qi in the Spring and Autumn Period.
Second, about? Jin has six qi? argue
1 thinking? Kim. Refers to bronze, so-called? Its gold and tin are combined into one? That is, bronze alloy is divided into six equal parts, bronze accounts for five parts, tin accounts for one part, and the ratio of copper to tin is 5 1, and so on.
2 thinking? Kim. Refers to pure copper, so-called? Its gold and tin are combined into one? That is, bronze alloy is divided into seven equal parts, bronze accounts for six parts, tin accounts for one part, and the ratio of copper to tin is 6 1, and so on.
3 and about? Half of Suk Kim? One is to divide bronze and tin equally, and the ratio of copper to tin is 1 to1; Another idea is? Half of gold and half of tin? That is to say, the copper-tin alloy is divided into three parts, tin is half of bronze, and the ratio of copper to tin is 2 1.
Third, archaeological materials and experimental evidence.
Scholars' experimental research on unearthed bronzes shows that:
(1) Zhong Ding is close to the first copper-tin ratio.
(2) The combination of halberd, slaying arrow and judge is close to the second copper-tin ratio.
(3) When the large blades are aligned, the tin content in both explanations is high.
④ The second kind of tin accounts for 33% of half of Suk Kim.
In fact, in many cases, it is impossible for the physical objects to be completely consistent with the records, because there are many influencing variables in the process of bronze casting and smelting, which need to be considered from many aspects, not just "textual research"? Literally, the calculation of percentage is in Liu Qi.
