摘　　要：利用激光剥蚀电感耦合等离子体原子发射光谱(LA-ICP-AES)和激光剥蚀电感耦合等离子体质谱(LA-ICP-MS)分析了一批中国古代钾玻璃。样品表面磨去100μm以上,并通过预剥蚀去除风化影响,设计剥蚀路径以消除元素分布不均匀影响。通过钙铝及其它微量元素将钾玻璃分成3个亚类,它们可能有不同的配方及制造中心;研究发现,钾玻璃着色剂类型多样化,有单质Cu,Mn2+,Cu2+,Co2+等;系统研究了钾玻璃的稀土元素特征,成功区分了九只岭地区及风门岭地区的钾玻璃;对两种方法在古代玻璃分析中的特点进行了探讨。Laser ablation inductively coupled plasma atomic emission spectrometry（LA-ICP-AES） and laser ablation inductively coupled plasma mass spectrometry（LA-ICP-MS） were applied to analyze ancient Chinese potash glass.Surfaces of glasses were polished over 100 μm,then pre-ablation was performed to avoid surface weathering effect,and laser ablation was performed in designed route to eliminate influence of heterogeneity.The glasses were classified into three subgroups by their lime and alumina concentrations,and they may have different recipe and production center.There were various colorants in these glass including metallic copper,and ions of manganese,copper and cobalt.The characteristics of rare earth elements of Chinese potash glass were studied for the first time and it successfully separated potash glass of Fengmenling and Jiuzhiling.The features of two methods in the studies of ancient glass were discussed.
