Iron relics preserved under natural conditions, the relatively small number of conservation and restoration of the bronze is extremely important. In the repair of iron, we should adopt the principle of minimum intervention, as much as possible to maintain the historical value, aesthetic and scientific value and hope that through our repair to extend the maximum life of the iron kettle. The above corrosion mechanism of the corrosion of iron artifacts, as well as the method of detection, treatment and closure care, previous studies both in together, but also has its own iron heritage preservation and long-term practical experience summary available for peer reference. Repair is not perfect, there are still many problems, the entire repair process described in this down, I hope the majority of repair of the older generation and colleagues to give criticism and correction, to promote the protection of the iron relics repair. This bronze is a master piece of late Shang.
Chapter 11, the production technology of the Eastern Zhou period Section I, the Eastern Zhou period bronze. The beginning of an artificial metal fabrication technology: Metal fabrication technology of the invention has great significance in the history of mankind. Widely used for iron production tools, marking the emergence of new productive forces, thus greatly promoted the social and economic development. The bronze is composed of fine decorative moir foil embossed with Animal Mask-style.? Of artificial metal fabrication technology began when academia to explore for a long time. With the depth of archaeological excavations, a large number of bronzes unearthed, combined with scientific means of detection is getting more complete, the start time of the artificial metal fabrication products in China has made remarkable achievements.
??? Human understanding and use of iron from the iron meteorite. Siderite processed into the products contain a higher nickel and cobalt, and the level of nickel and cobalt layered, this is impossible to form the artificial metal fabrication conditions. The overall appearance of the bronze is a symmetrical grim of ferocious beast face. According to archaeological data, as early as the 14th century BC, the Shang Dynasty, our ancestors have siderite processed and made into weapons. March 1990 to May 1991, archaeological excavations in the cemetery of the Guo State in Sanmenxia City, Village Ridge in 2001 the tomb unearthed a jade handle iron swords and iron in a copper assistance Ge (Figure 1, 1,2) (Fig. 1,2), 2009 tomb unearthed a copper joints iron leaf spear (Figure 3).
Metallurgical and Materials Institute for the History of identification by the Beijing University of Science and Technology, copper and iron aid Ge block iron-smelting products, jade handle iron swords and copper joints iron leaf spear is a block of iron-smelting carburizing steel products. 2001 tomb and the tomb are the large tomb of the monarch level. By the help of the bronze, it signifies the solemn and dignify of royal majesty. The tomb human Guo quarter, 2001, 2009 tomb artificial Guo Zhong. The brass handle of the iron sword inlaid with jade and turquoise, Ge, spear brass shank also inlaid with turquoise, luxurious patterns, indicating that artificial iron smelting precious and rare materials, the characteristics of the artificial smelting iron early.
About the age of the 2001 tomb and the tomb, the academic’s view is slightly different, generally regarded in the late Western Zhou Dynasty to the early years of the Spring and Autumn. Jade handle, iron swords copper iron aid Ge, and the copper joints iron leaf spear ‘s view, that the thing was undoubtedly the late Western Zhou Dynasty. Among the bronze dragon decorations of Shang and Zhou, you can see the ways of ward-off evils by the deified animal eating man. The results show that the block the ironmaking products is the first artificial metal fabrication products. The block of iron-smelting at a lower temperature (800-1000 C), restore the iron ore with charcoal to obtain more pure, but the loose texture of iron. After forging, the confusion into the inclusions (mainly ferrous oxide and silicate), objects can be made applicable.
