摘要
Abstract
To preliminarily reveal the technical characteristics of bronzes unearthed from the Guangyangcheng cemetery,61 Han Dynasty bronzes from the cemetery were examined through metallographic structural observation,elemental compositional analysis and lead isotope ratio determination.The results show that the 61 bronze artifacts exhibited two types of microstructures:casting(59)and post-casting cold working(2).Lead-tin bronze was the predominant alloy type,accounting for 96.7％of the samples,with one tin bronze and one lead-arsenic bronze also identified.Lead isotope ratio analysis revealed that 60 samples had ordinary lead,while one contained highly radioactive lead.The lead used in the Western Han bronze was derived from a wider range of sources than that used in the Eastern Han bronze.Specifically,lead materials of Class L and H,used during the Western Han Dynasty,were no longer used in the Eastern Han Dynasty.The Class H lead was closely linked to the Yan culture,and may have originated from the Yan-Liao area.In the Eastern Han Dynasty,Class B lead began to be widely adopted.The Class A,B and C leads were used in both the Western Han and Eastern Han periods,but their sources were not entirely overlapping,indicating distinct supply channels across the two periods.关键词
