一组来自今保加利亚三个地点的发现（器皿、玻璃坯块、窗玻璃）被选为公元6世纪多瑙河下游地区玻璃流通和使用的代表。AD.总共有79个样品进行了分析，EPMA和/或LA-ICP-MS技术。根据参考玻璃的测量和从两种技术分析的考古玻璃的代表性样品获得的结果对每个分析运行的数据质量进行评估。结合EPMA和LA-ICP-MS数据允许形成足够一致和统一的一组主要结果。正如在早期的初步论文中已经提出的那样，只有一种玻璃成分被发现在公元6世纪占主导地位。该地区的背景。目前的研究承认这第六个C。来自多瑙河下游的玻璃与所谓的“Serie 2.1”相同。'定义为D. Foy和同事（2003年）在法国南部和北非的各种集会。主要的，次要的和微量的氧化物的证据表明，这是一个独特的主要玻璃组合物，与富铁的子组内的主要群体暂时分化。因此，试图将其相对于该地区的其他主要原生成分进行分类。这一解释是，第六C。玻璃不应与HIMT玻璃联系在一起，尽管它们之间由于氧化铁、锰和二氧化钛浓度升高而具有名义上的相似性。相反，第六世纪的地球化学特征之间可能存在联系。玻璃和早期的锰脱色玻璃，相当于“系列3.2。”D。Foy和同事（2003）建议。这可能意味着使用的沙子来自大致相同的地质区域，因此有可能是第六个C。玻璃和锰脱色组合物可能具有共同的来源。(C)2015作者爱思唯尔有限公司出版
A group of finds (vessels, raw glass chunks, windowpanes) from three sites in present-day Bulgaria was selected as representative of the circulation and usage of glass in the Lower Danube region during the 6th c. AD. In total, 79 samples were analysed by EPMA and/or LA-ICP-MS techniques. The data quality was assessed for each analytical run according to the measurement of reference glasses and to pairs of results obtained from representative samples of archaeological glass analysed by both techniques. Combining EPMA and LA-ICP-MS data allowed a sufficiently consistent and unified set of primary results to be formed. As already suggested in an earlier preliminary paper, only a single glass composition was found to dominate the 6th c. contexts in the region. The current study recognises this 6th c. glass from the Lower Danube as identical with the so called 'Serie 2.1.' defined by D. Foy and co-workers (2003) in various assemblages in Southern France and North Africa. The major, minor and trace oxide evidence presented here indicates that this is a distinct primary glass composition, with an iron-rich sub-group tentatively differentiated within the main group. Accordingly, an attempt is made to situate it relative to the other main primary compositions in the region. The proposed interpretation is that the 6th c. glass should not be linked to the HIMT glass despite the nominal similarity between them due to their elevated iron oxide, manganese, and titania concentrations. Instead, a possible link between the geochemical characteristics of the 6th c. glass and an earlier group of manganese decolourised glass, equivalent to 'Serie 3.2.' outlined by D. Foy and co-workers (2003) is suggested. This may imply the use of sand from a broadly identical geological area, hence it is possible that both the 6th c. glass and the manganese decolourised composition are likely to share a common origin.
