摘要
一、序论中国青铜兵器发展到东周时期,出于诸侯争霸的需要,兵器的形制和制作技术有了显著进步,铁刃铜戈、铁铤铜镞以及调节脊与从部含锡量以获得刚柔相济性能的青铜复合剑技术,均出现于这个时期。吴、越的兵器制作技术更是名满天下。《考工记·总序》:'吴粤(越)之剑,迂乎其地而弗能为良。'从出土实物考察,古文献对吴越兵器精良的评价并不过分。
In the Wu and Yue areas of the Eastern Zhou period,there were bronze swords,spear- heards and ge dagger-axes bearing on the surface a regularly-spread lozenge pattern,which, as seen on the famous sword of Yue Prince Gou Jian and spear of Wu Prince Fu Chai,is not inlaid by mechanical means and possesses high decorativeness.This splendid decoration has drawn much attention from Chinese and foreign archaeologists and scientists since the 1970s, but no explicit report had been released and no successful replica obtained in previous studies. A fragment of a lozenge pattern sword was examined and tested by our research group. It was discovered that the sword was cast in bronze and that the surface bore in the decorated zones a thin fine dendrite layer different from the body in structure and composition.Several methods for revealing the making technique of the layer were tested,and one of them, named tin-rich paste coating,was found to be able to produce a layer similar to that on the ancient sword in form.structure and composition and with a high corrosion-resisting quality suitable to protecting the sword body.Through accelerated corrosion tests on lozenge pattern reproductions,the yellow and white colors on their surface changed into bright-black and grayish-black similar to those on the sample.Thus the mystery of the ancient technique for producing the'veiled lozenge pattern'has been successfully solved.
