| 铜雕纯度较高的铅、锡、铜，再根据需要按一定比例配在一起铸造而成的。铜锈是随着周围环境的变化铜雕表面产生的化学反应。此反应会经历休眠期和生长期。铜锈的颜色以绿、蓝为主。 Copper carving with high purity of lead, tin, copper, and then according to the needs of a certain proportion of casting together. Copper rust is a chemical reaction on the surface of copper carving with the change of surrounding environment. This response goes through dormancy and growth. The color of copper rust is mainly green and blue. 存世时间短、保存较完好的铜雕表面多数都有"水银沁"或"黑漆古"等漂亮的皮壳。 Most of the copper carvings with short survival time and good preservation have beautiful leather shells such as "mercury Qin" or "black lacquer ancient". 陈年自然锈蚀，其锈蚀有明显的层次，一般从外到内纵向分为锈土结合层、主体锈层、地子锈层。 Aged natural rust, its rust has obvious layers, generally from outside to inside longitudinal divided into rust soil bonding layer, main rust layer, ground rust layer. 锈土结合层上常见锈蚀与地下环境中的附着物，如泥土或碳化后的草木屑等；在锈土结合层的下面有一层绿色或蓝色的结晶锈就是主体锈层；在主体锈层以下就是紧贴铜雕的黑或红褐色的氧化膜层，即地子锈层。 Attachments between rust and underground environment, such as soil or carbonized sawdust, are common on the rust-soil bonding layer. Under the rust-soil bonding layer, a green or blue crystalline rust is the main rust layer, and below the main rust layer, a black or reddish-brown oxide film, which is closely attached to the copper carving, is the ground rust layer. 这3层锈蚀次序分明、排列合理，有的铜雕没有锈土结合层，甚至没有主体锈层，但是决不能没有地子锈层，这对于分辨老锈新锈十分关键。而大多数仿古铜雕由于其经历的时间较短，通常只有一层浮锈，颜色单一、结构松散、附着较差，如果去掉浮锈会直接露出新鲜的铜体。 These three layers of rust have distinct order and reasonable arrangement. Some copper carvings have no rust-soil bonding layer or even main rust layer, but they must not be without rust layer, which is very important for distinguishing old rust from new rust. Most of the antique bronze sculptures have only one layer of floating rust due to their short experience. The color is single, the structure is loose and the adhesion is poor. If the floating rust is removed, fresh copper body will be exposed directly. |
