东南亚铁器时代玻璃玦科学研究

44 glass Jue collected in Southeast Asia have been scientifically studied by means of X-ray fluorescence spectrometry (XRF), optical coherence tomography (OCT), ultra-depth optical microscopy (OM) and confocal Raman microspectroscopy. Chemical compositions, phase components, internal physical structures of glassy matrix of the Jue samples are obtained. According to the scientific analysis results, the glass types of the Jue samples can be classified into three types, potash glass, soda lime glass and potash-lead glass. 42 samples belong to potash glass, and the 2 samples left belong to sodium-calcium glass and potassium-lead glass, respectively. Two subgroups, m-K-Al subgroup and m-K-Ca-Al subgroup, are found for potash glass. Only 4 potash glass samples belong to m-K-Ca-Al subgroup, the others are m-K-Al subgroup potash glass. Drawing, casting and cold-working techniques were applied for the glass making. Most samples are colored by iron ion, or colored by iron and copper ions. Only one sample is opacified by lead tin yellow.

研究人员采用X射线荧光光谱法（XRF）、光学相干断层扫描（OCT）、超景深光学显微镜（OM）以及共聚焦拉曼显微光谱法，对44件征集自东南亚的玻璃珏样品开展了科学研究。研究获取了该批玻璃珏样品的化学成分、物相组成及玻璃基体的内部物理结构。基于科学分析结果，该批玻璃珏样品可分为三类：钾玻璃、钠钙玻璃与钾铅玻璃。其中42件样品属于钾玻璃，剩余2件分别为钠钙玻璃与钾铅玻璃。钾玻璃可进一步划分为两个亚组：m-K-Al亚组与m-K-Ca-Al亚组；仅有4件钾玻璃样品隶属于m-K-Ca-Al亚组，其余均为m-K-Al亚组钾玻璃。该批玻璃制品采用拉制、铸造与冷加工工艺制备。多数样品以铁离子着色，部分样品由铁离子与铜离子共同着色；仅有1件样品通过铅锡黄实现乳浊。
