本研究利用能量色散型X射线荧光光谱分析、共聚焦激光拉曼光谱分析、光学相干层析成像、超景深光学显微观测等多种方法对广西越州故城遗址出土的印度-太平洋玻璃珠饰进行科技分析,获取了玻璃珠的化学成分、物相结构、内部物理结构、表面显微形貌等综合物理化学信息,确定了玻璃珠的玻璃体系、制作工艺(着色工艺、成形工艺)和产地来源,探讨了以丝绸之路为主线的国内发现魏晋南北朝时期印度-太平洋玻璃珠可能的输入路线。广西越州故城遗址发现的印度-太平洋玻璃珠为中外文明交流提供了新实物证据,对深入研究我国南北朝时期中外文明交流具有十分重要的学术价值和研究意义。 相似文献

漆器是研究古文化的实物资料,多有精美纹饰和铭文,但考古发掘出土的漆器多有饱水、糟朽和变形等病害,甚至胎体完全腐蚀,仅剩漆膜,且无法复原。在研究前人对漆膜保护的基础上,提出一种平整漆膜的保护方法,整形脱水后以棉纸为背衬、虫胶漆为粘接剂粘接漆膜,再用镶嵌磁铁的有机玻璃板夹住固定。成功保护了长沙风篷岭汉墓出土的60余件漆膜,为今后研究漆膜的保护修复方法提供参考作用。 相似文献

Lead isotopes, thin‐ and sherd‐section analyses are coupled on pottery‐vessel fragments excavated from the Late Bronze Age site of Hala Sultan Tekke (south‐east Cyprus) and representing fabrics used for the production of storage and trade containers. The fabrics of the sherds are first described according to general macroscopic observations. Based on the different fabrics identified, a petrographic analysis is carried out on thin sections and compared to lead isotope results on the same samples. This study shows that a specific fabric corresponds to a specific lead isotopic composition and proposes different sources for the various groups of associated sherds/fabrics. It also demonstrates the compatibility and complementarity of petrography and lead isotopes within pottery provenance study. 相似文献

Radiogenic lead and strontium isotope data are presented for lead‐ and calcium carbonate/barium sulphate‐containing paint and ground samples from 15 paintings, executed between 1844 and 1871, by 19th‐century Canadian artist Cornelius Krieghoff. Like many artists of this era, Krieghoff used lead‐based pigments such as lead white, chrome yellow and Naples yellow, and extenders such as calcium carbonate and barium sulphate. The lead isotope analyses of the majority of these pigments are consistent with the isotopic compositions of lead mined from European lead deposits in England and/or Germany. However, three samples from Krieghoff's early career yield lead isotope compositions that are much more radiogenic than European sources. The lead isotope compositions of these three samples are consistent with the addition of a more radiogenic lead component that is similar to the lead derived from North American lead deposits in Missouri and Illinois (Mississippi Valley Pb–Zn type deposits). The strontium isotope compositions of the extenders suggest that the raw materials for calcium carbonate or barium sulphate extenders were largely derived from Palaeozoic to modern‐day marine environments. This study shows that pigments manufactured from North American lead were being incorporated into Canadian paintings as early as 1844. 相似文献

Sijilmâsa (south-east Morocco) was one of the most strategic cities in a far-reaching exchange network, that is, the Trans-Saharan trade, linking the Maghreb with West Africa during the medieval period (from the 8th to the 15th century CE). It was also one of the most important gold and silver monetary workshops at the time. If gold came from West Africa, we know from written sources that silver was produced in Morocco, although archaeological evidence of silver mining and smelting has remained elusive. Thanks to a thorough analysis of the lead isotopic data from silver mining districts in Morocco and from ores and slags of our study, we were able to refine the tracing of our materials and provide tangible evidence of medieval mining in the close hinterland of Sijilmâsa city. 相似文献

Substantial databases of elemental and isotopic analyses of ancient glass exist and are used to investigate raw material origin, trade, exchange, and processes such as mixing and recycling. However, the chemistry of archaeological glass may be challenging to the untrained. The paper provides structured information on the origin of chemical elements and their isotopes in ancient glass. It details some of the functions of individual elements in the glass and from which raw material(s) or process(es) they originate. 相似文献

A set of artifacts, apparently associated with human remains (one tooth), from Pine Island, Alabama, was donated to the Yale Peabody Museum of Natural History in 1915. In preparation for repatriation, this collection was investigated extensively by a volunteer team. This paper reports the results of this analysis, focusing especially on a new type of trade gun and the glass beads. The goal of the research is to provide an accurate date for the collection to assist in identifying the Native American group represented. 相似文献

Two sets of wine bottles dated between the end of the 17th and the 19th centuries were characterized by means of μ‐PIXE (major and minor elements) and LA–ICP–MS (trace and REE elements). The fragmented wine bottles were recovered from two archaeological contexts in Lisbon and reach a total of 79 fragments. One of the archaeological bottle sets comes from a house structure that collapsed during the major earthquake in 1755, providing a precise terminus ante quem. The second set comes from the exploratory archaeological intervention performed in Rua do Arsenal, where the Côrte‐Real Palace (built in the 16th century), was discovered. From this site, posterior contexts dated up to the 19th century were considered. This systematic study allowed the glass to be identified as high‐lime, low‐alkali (HLLA) for all the considered chronologies. However, the 19th‐century bottles have a different HLLA composition, suggesting the use of synthetic soda. Comparison with data from literature showed some similarity with English, Belgium and French reported compositions. This is the first systematic attempt to characterize the composition of glass wine bottles circulating in Portugal, giving new insights into their probable provenances, and on the exchange between Portugal and its trading allies. 相似文献
