LA-ICP-AES分析丝绸之路且末出土玻璃器成分特点

位于丝绸之路南道上的新疆且末古国扎滚鲁克墓地M133墓和M49墓分别出土了一批珍贵的玻璃料珠和一件玻璃杯，时代为东汉-南北朝时期(公元1～6世纪)。利用激光刻蚀电感耦合等离子体发射光谱(LA-ICP-AES)对这批样品进行化学成分分析，并讨论了这一方法的优势与准确性。分析数据显示，这批样品具有典型的西方钠钙玻璃的成分特点。根据现代西方古代玻璃研究体系中助熔剂的不同，这批玻璃又划分为泡碱玻璃和植物灰玻璃两类，并对玻璃成分的相似性与差异进行探讨。该研究以玻璃为载体反映了且末古国与西方的贸易与文化交流的历史，而且为玻璃的产地来源与制作工艺研究提供了重要的参考。

Characteristics of Chemical Composition of Glass Finds from the Qiemo Tomb Sites on the Silk Road

Qiemo was an ancient country on the south branch of the Silk Road. The Zagunluke tomb site is located at the Qiemo County of the Xinjiang Uygur Autonomous Region. Glass beads and only colourless glass cup were excavated from the 3rd cultural layer of the tomb site M133 and M49, dated between the 1st AD-6th AD. LA-ICP-AES was applied to analyse chemical composition of these glass finds with the corning glass as reference. According to the result, characteristics of chemical composition are very similar to typical soda-lime glass, which indicates the glasses were imported productions from the west. These soda-lime glasses were divided into two groups in terms of flux source: natron glass and plant ash glass. This analytical research indicates the history of glass trade and communication between the East and the West on the Silk Road.
