本文以剔花、绞胎、黑釉跳刀刻花、红绿彩和孔雀蓝釉等“磁州窑类型”几种瓷器为对象,在以往研究的基础上,通过有关遗物和考古资料——特别是一些重要新发现,对这几个品种的年代与产地作进一步“细化”,从而提出一些新见解。 相似文献

不同于新出土青铜器上的锈蚀物,博物馆藏金属器物上经常可见浅蓝色铜的锈蚀物。为辨别和探析其成因,通过采用扫描电子显微镜-能谱仪(SEM-EDX)、X射线衍射仪(XRD)和激光拉曼光谱仪(Raman)进行元素成分和物相综合分析,发现其为铜的有机盐。这些有机盐包括简单(或碱式)的甲酸铜和乙酸铜,也包括复杂的含有钠离子和碳酸根的乙酸铜NaCu(CO3)(CH3CO2)、含有钠离子和氧离子的水合甲酸铜Cu4Na4O(HCOO)8(OH)2·4H2O。这种浅蓝色铜的有机盐形成根源主要有两种:储存或展览环境的不当;用于除锈的化学试剂的残留。要杜绝这类锈蚀物的形成需要确保储存和展览器物的环境低湿度且无有机酸释放材料的存在。对经过化学处理的器物应确保将化学试剂清理干净且无任何残留以绝后患。对复合材料器物的处理更应谨慎,因为对不同材质的处理和保存环境要求不一样,要个例对待。 相似文献

Here, we report on the analytical findings and their cultural implications of a multidisciplinary study of the pre‐Columbian Codex Fejérváry‐Mayer. Today conserved at the World Museum in Liverpool, it is one of the finest Mesoamerican codices among the few extant. Thanks to the exploitation of non‐invasive analytical methodologies accessible through the MOLAB European mobile facility, the study allowed us to disclose the chemical composition of the painting materials used in the codex, which have never been analysed before. The results are discussed and compared with the outcomes of previous studies on other Mesoamerican codices. 相似文献

A method using the ratios between MnO, Fe2O3 and CoO to differentiate the cobalt sources for Chinese blue‐and‐white porcelain was developed in Oxford in the 1950s using X‐ray fluorescence (XRF) analysis directly on the glaze. In this paper, six blue‐and‐white porcelain sherds from the Luomaqiao kiln were analysed by XRF on the glaze and by scanning electron microscopy with energy‐dispersive spectrometry (SEM‐EDS) in cross‐section. The ratios between MnO, Fe2O3 and CoO calculated by quantitative XRF and EDS analyses are different. The analysis depths for MnO, Fe2O3 and CoO are < 60 μm by XRF analysis. However, the average glaze thickness of samples is > 400 μm, and the MnO, Fe2O3 and CoO mainly remain in the lower layer of the glaze, which is beyond the analysis depths of XRF analysis. The limitations of major and minor quantitative analyses for differentiating cobalt sources are discussed. 相似文献

本文探讨了14世纪以前钴蓝釉料在西亚和中国的使用情况,指出钴蓝在西亚有着悠久的使用传统,出于对青金石的崇尚,钴蓝釉料被广泛运用在模仿青佥石色彩的人工制品上,主要包括釉面砖、玻璃、陶器等。而在14世纪以前的中国,钴蓝釉料的使用出现较晚,运用也缺乏普遍性、延续性。通过西亚和中国情况的对比,笔者对元青花在14世纪得以突然勃兴的原因.提出了新的见解。 相似文献

A multi-technique characterization and a provenance study of the black pigment used in Cucuteni pottery painting (Neolithic age, Romania) were carried out. 127 Cucuteni shards were analyzed by Raman spectrometry. The main components of this pigment are pyrolusite and/or jacobsite. Hematite and quartz are frequent minor components and Ti oxides were seldom found. The manganiferous corpuscles discovered at Neam? county (eastern part of Romania) were the raw material of the Cucuteni black pigment. The Mn corpuscles were studied using XRD, Raman, FT-IR and Atomic Absorption Spectrometry. The main components are birnessite, goethite and frequently, quartz. Raw material was subjected to a temperature of 750 °C for 6 h and,once cooled, analyzed through Raman and FT-IR spectrometry. Pyrolusite, hematite and quartz were found in the heated powder sample. 相似文献

The Yuan Qinghua porcelain produced in the city of Jingdezhen, in China, mainly includes the gaudy blue type, a blue–grey or grey‐coloured type and the type featuring a blue colour with a slight amount of grey. For a long time, only the gaudy blue type was focused on and discussed, while the other two types, which contain equally important information with regard to recovering the manufacturing technology of Yuan Qinghua, were always ignored by scientific researchers. In this paper, by using micro X‐ray fluorescence spectroscopy (μ‐XRF), spectrophotometry and optical microscopy, all three different types of Yuan Qinghua porcelain are analysed systemically and, based on the analyses of the body, the glaze and the blue decoration, the differences in the materials and the manufacturing technologies of the three different types are discussed. This not only provides a good basis for the reconstruction of the whole picture of the manufacturing process of Yuan Qinghua porcelains in Jingdezhen, but also contributes to database‐building for the identification of Qinghua porcelain. 相似文献

A micro-invasive technique is presented that enables pigment sampling from individual layers of a painting cross-section by obtaining a furrow 10–50 μm wide of chosen length. Combined with increased sensitivity of lead (Pb) isotope analysis using multicollector inductively coupled plasma mass spectrometry (MC-ICPMS) equipped with a 1013 Ω resistor or a Pb double-spike technique, the amount of Pb needed for isotopic analysis is drastically reduced, while maintaining a relative 2 SD precision for 206Pb/204Pb of < 0.02%. The methodology proved able to characterize Pb isotope differences within paint layers. 相似文献
