缓蚀剂BTA与AMT保护青铜文物的对比研究

对比了BTA和AMT的物理性质、缓蚀青铜的外观效果、中性和酸性介质中的腐蚀抑制性能、粉状锈清洗、成膜结构,各自优缺点,BTA和AMT都可以有效地保护青铜器,AMT还需时间检验,BTA和AMT保护青铜器研究工作需要继续深入。     

试论四川地区战国墓中的青铜工具

四川地区战国墓葬所出土的青铜器中最具特色的是巴蜀风格的容器与兵器。此外 ,在这些墓葬中普遍随葬青铜工具的现象也是不可忽视的。四川地区的战国墓葬中一般均有青铜工具出土。 (详见表一 ) ① 即使不出青铜工具 ,也会出土一些铁质工具。如大邑五龙乡土坑墓就出土有铁斧、铁环首刀等 ② 。四川地区战国墓中出土的青铜工具 ,不仅数量多、分布广 ,而且种类丰富。现根据已有资料 ,对战国时期四川地区青铜工具的型式演变、年代分期、功用及相关问题谈一点初步认识 ,以求正于各位同仁。一、青铜工具的型式四川地区的战国墓中出土的青铜工具主要…     

论新识的一种周系铸铜工具

周公庙遗址出土的"圆锥体中空器"是一种铸铜工具,该类器物应属"周系"文化因素,其流行时代早于西周早期偏晚阶段.     

三星堆青铜树象征性研究

对三星堆遗址二号祭祀坑出土的青铜神树的研究现状进行回顾,从宗教人类学与萨满艺术的角度对其作了新的探讨,认为树与鸟相结合的表现形式是萨满艺术中“世界之轴”或“萨满树”的典型特征,是萨满和巫师进行祭祀时沟通天地的主要道具.文章呼吁,对这类意识信仰的产品我们除了文献资料以外,还应该利用宗教人类学方法来深入解读其深层的涵义.     

不稳定青铜器的处理方法

“青铜病”的稳定问题对文物保护工作者来说还是一个挑战。文献报道了不少的处理方法,每种方法都有其优点及不足之处。本文对“青铜病”的处理方法进行了考察,主要讨论了化学封护法的应用及其未来的研究方向。     

Quantitative characterization of archaeological bronzes based on thermal and compositional analysis

Pulsed thermography has been applied to the quantitative characterization of the insertions of two ancient bronzes, the Boxer at Rest and the Hellenistic Prince. The analysis of the thermographic signal time dependence performed by a specifically developed model enabled the evaluation of the insertions’ thickness and of elements which could provide indications about the procedure followed for their insertion. This could be achieved by exploiting a semi-empirical relation establishing the thermal diffusivity dependence on the total effective weighted concentration of Sn and Pb atoms obtained from the analysis of the values determined on samples containing different concentrations of Sn and Pb.     

Did China Import Metals from Africa in the Bronze Age?

The origins of the copper, tin and lead for China's rich Bronze Age cultures are a major topic in archaeological research, with significant contributions being made by archaeological fieldwork, archaeometallurgical investigations and geochemical considerations. Here, we investigate a recent claim that the greater part of the Shang‐period metalwork was made using metals from Africa, imported together with the necessary know‐how to produce tin bronze. A brief review of the current status of lead isotopic study on Shang‐period bronze artefacts is provided first, clarifying a few key issues involved in this discussion. It is then shown that there is no archaeological or isotopic basis for bulk metal transfer between Africa and China during the Shang period, and that the copper and lead in Shang bronze with a strongly radiogenic signature is not likely to be from Africa. We call for collaborative interdisciplinary research to address the vexing question of the Shang period's metal sources, focusing on smelting sites in geologically defined potential source regions and casting workshops identified at a number of Shang settlements.
