摘要
采用多元统计方法对四川、重庆、贵州、广西、广东地区出土的100余个古玻璃样品的化学成分数据进行了分析处理。结果表明：中国南方和西南地区的古玻璃制品主要由具有中国特色的铅钡硅酸盐玻璃和钾硅酸盐玻璃组成，可细分为五大系统类别：K2O-CaO（～10wt％）-SiO2系统、K2O-SiO2系统、PbO-BaO-SiO2系统、PbO（～25wt％）-BaO-SiO2系统、CaO-PbO（～40wt％）-BaO—SiO2系统。用因子分析探讨了我国汉代南方和西南地区的玻璃本地生产情况，表明该地区在汉代已经拥有自主生产古玻璃的能力。实验结果和实验数据处理方法对研究古代丝绸之路上古玻璃的生产和技术交流提供了新途径。
Depending on its superior natural resources and incomparable geographic environments, the southern and southwestern China has become a major prosperous center for culture and economy since the Han Dynasty （206BC - 220AD） in which the Ba-Shu culture, Southern - Yue culture, Central China culture and Chu culture gather together and play the historical roles. Particularly in Han Dynasty, there are great quantities of glass articles unearthed with good quality and different categories spread all over the southern and southwestern China. In this study, multivariate statistical analysis was applied to the PIXE （proton induced X ray emission） results to verify the category and origin of 104 selected ancient Chinese glasses, based on their chemical compositions. The results show that the ancient glasses unearthed in Sichuan, Chongqing, Guizhou, Guangxi and Guangdong during the Warring States and Han Dynasty are mainly attributed to the lead - barium silicate and the potassium silicate system glasses besides a small quantity of high - lead and high calcium ones, which could be classified in detail to five groups： K2O - CaO（ - 10wt% ） SiO2 system, K2O - SiO2 system, PbO - BaO - SiO2 system, PbO（ - 25wt% ） BaO - SiO2 system and CaO PbO（ - 40wt% ） BaO - SiO2 system. In all, these two kinds of glasses are often excavated in the same era and the same place. Potassium silicate system glasses were mainly produced in Guangxi province, and Sichuan, Chongqing and Guizhou areas had a relative balanced excavation of these two kinds of glasses. The experimental results demonstrate the self- made characteristic of ancient glasses unearthed from each place in southern and southwestern China. The conclusion and data processing method are surely favorable in studying the technological progress of ancient glasses along the ancient Silk Roads.
