新疆尉犁县营盘墓地出土夹金属箔层玻璃珠研究

Research on Metal Foil Glass Beads from the Yingpan Cemetery in Yuli,Xinjiang

营盘墓地位于新疆巴音郭楞蒙古自治州,是汉晋时期由楼兰向西沿孔雀河至西域腹地交通线上的一处枢纽重镇。墓葬中出土了一批夹金属箔层玻璃珠,为了解其成分及制作工艺特点,对M7出土的夹金属箔层玻璃珠进行了科学检测分析,结果表明,它们均属于钠钙玻璃系统,以植物灰作助熔剂,通过拉制技术制作而成,特征与印巴地区接近;在制作夹金玻璃珠时,古代工匠通过多种方式降低生产成本,以寻求高利润。本研究为讨论古代玻璃珠的传播提供了新的证据。

The Yingpan site is located in Bayingolin Mongolian Autonomous Prefecture,Xinjiang.It is a transportation hub of cultural exchange between the East and the West during the Han and Jin Dynasties.A large number of metal foil glass beads have been unearthed in the tombs.This paper presents the analytical results of chemical compositions and manufacturing technology of metal foil glass beads from tomb no.M7 by applying various techniques.Our analytical results show that these beads are all soda-lime glass with plant ash as flux and made by drawing.The characteristics of these samples are similar to those discovered in the India-Pakistan region.In order to reduce production costs,the craftsmen added certain amount of silver into the gold foil or used impure gold mineral during the manufacturing process of gold glass beads.This research provides new evidence for discussing the spread of ancient glass beads in Eurasia.
