料珠在我国分布非常广泛，它最早出现在西周，到两汉以后逐渐衰落。学界对中原地区的料珠进行了较充分的研究，但是对于料珠的传播过程、传播路线及中西方料珠制作工艺的相互影响研究还很薄弱。本项目以近年来新疆丝绸之路沿线出土料珠为研究对象，采用多种核分析技术（LA-ICP-AES、SR-μCT、EDXRF、XAFS等），主要研究：（1）料珠的成分体系，厘清料珠的主体成分、乳浊剂成分和呈色元素种类；（2）结合显微结构分析和模拟制备，对不同制作工艺与料珠显微结构的关系建立模型，从而揭示出土料珠的制作工艺；（3）结合成分分析、显微结构分析与XAFS分析，对料珠的呈色机理进行研究；（4）在此基础上，对不同地区、不同形态的料珠进行比较研究。本项目的开展，一方面可以从新的角度探讨中国玻璃制作的起源问题，另一方面对深入了解不同文明、不同人群之间玻璃制作工艺、玻璃制品传播及相应文化交流具有重要意义。

The glass beads distributed broadly in China, it first emerged in the West Zhou dynasty and it declined after West Han and East Han dynasties. The previous studies mainly focused on central part of China. Several important issues which include the spread process, spread route of glass beads and the manufacture interaction between China and western civilizations are still weak. This project main focus on the glass beads which were excavated from the sites along the Silk Road in Xinjiang in the last few years. The LA-ICP-AES, EDXRF, SR-μCT , XAFS and other nuclear analysis methods will be used for the following studies: (1) The chemical compositions of the glass beads. The study will identify the raw materials of the main body, the opacifier and the coloring aging of the glass beads; (2) combined the microstructure analysis and simulating manufacture experiment to build the statistical model to connect the characteristics of microstructure and the relative manufacture process. The manufacture process of ancient glass beads will be revealed based on these analysis; (3) combined the chemical composition, microstructure and XAFS analysis to study the coloration mechanism; (4) Based on these results, the glass beads from different areas and different types glass beads will be compared. The project will make significant contribution to the issue of the origin of the glass making in China, furthermore, it has remarkable meaning to understand the spread of the glass beads and the interaction of the manufacture process between different civilizations.
