摘要
无损分析是文物样品研究的重要内容, 研究中采用便携式能量色散型X射线荧光光谱仪(pXRF)和激光拉曼光谱仪(LRS), 对河南宝丰和新郑出土的21件战国晚期到汉代的硅酸盐制品进行了化学成分分析和微区物相分析。 依据化学成分分析结果, 将样品划分为铅钡硅酸盐玻璃、 钾硅酸盐玻璃、 釉砂和铅钡釉砂四类分别进行讨论, 并对样品的着色机理进行了初步探讨; 利用激光拉曼光谱在部分蜻蜓眼和圆环珠蓝色颜料中检测到了中国蓝(BaCuSi4O10)、 中国紫(BaCuSi2O6)和中国深蓝(BaCu2Si2O7), 同时成功确定了部分样品中存在石英、 方解石、 碳酸铅、 煅棕土、 绿土等多种物相; 结合考古研究资料, 对这些样品的来源进行了简要讨论, 其中本实验铅钡硅酸盐玻璃、 钾硅酸盐玻璃耳珰和铅钡釉砂为我国自制, 而另外1件釉砂可能属于舶来品, 反映了我国古代中原各地区间, 以及中原与西域间有着广泛的文化技术交流。 便携式能量色散型X射线荧光光谱仪和激光拉曼光谱仪的相互结合, 能够提供硅酸盐制品的有效化学成分和结构信息, 在文物科学分析中显示出特有的优势, 为其考古研究提供有益的信息。
Abstract
Nondestructive analysis plays an important role in the studies of ancient artifacts. The present paper reports the chemical compositions and micro-area phases of 21 silicate artifacts samples analyzed by portable X-ray fluorescence spectrometer and laser Raman spectrometer. Based on the chemical compositions, these samples can be divided into PbO-BaO-SiO2, K2O-SiO2 glass systems, faience and PbO-BaO glassy faience which were discussed respectively, and preliminary investigation of colorants in different parts of some samples was also involved. By laser Raman spectroscopy, Chinese blue(BaCuSi4O10), Chinese purple(BaCuSi2O6) and Chinese dark blue(BaCu2Si2O7) were identified invasively in the blue pigment of some eye beads and circle beads, and then a variety of mineral phase including quartz, calcite, lead carbonate, burnt umber and terre verte were also analyzed successfully in the same way. According to the archaeological research results, the provenances of these samples were discussed briefly. PbO-BaO-SiO2 glass, K2O-SiO2 ear pendant and PbO-BaO glassy faience were made in China while the faience was suspected to be from the west. Those results illustrated the communications of culture and technologies among different regions of ancient China, and between ancient China and the western regions. The combination of portable X-ray fluorescence spectrometer and laser Raman spectrometer can provide chemical and phase information of relics, and has great advantages in scientific analysis of ancient artifacts, which supports future studies of archaeology.
