引言东京大学文学部陈列室收藏有两件二里冈时期青铜爵,均为20世纪30年代由江上波夫从中国运到日本的。本文以这两件青铜爵为主要线索进行研究,尤其是着眼于它们的制造技术,进而对二里头时期至二里冈时期的青铜器制造技术的演变进行研究。首先,笔者对东大收藏的两件青铜爵进行了仔细的观察。观察时,不仅观察了这两件爵的器物类型,而且还关注了它们的铸造痕迹等细节情况。其次,本文根据器物类型确定了这两件爵的更详细的年代范围。最后,本文根据器物表面留下的范线尝试复原这两件爵的合范方式,并对基于器物类型与基于合范方式确定的年代的差异进行探讨。 Introduction The Department of Literature of the University of Tokyo has two collections of bronze jugs of the two years of Ritsumekang from the China to Japan in the 1930s. In this paper, we mainly study the two Bronze Jue as clues, especially focusing on their manufacturing technology, and then studying the evolution of the bronze manufacturing techniques from Erlitou period to Erlitang period. First of all, I carefully observed the two pieces of bronze medal collected by Dongda University. Observation, not only observed the two pieces of jade utensils type, but also concerned about their casting traces and other details. Second, this article determines the more detailed chronology of these two pieces based on the type of artifact. Finally, this article attempts to reconstruct the two pieces of Jue’s method based on the line left by the surface of the object, and discusses the differences between the types based on the type of object and the period determined based on the method of norm.
