The subject of this study consists of 17 ancient glass fragments from the island of Ustica (Palermo, Italy) obtained from local museums. All the 17 glass fragments are stratigraphically decontextualized, as they were collected by archaeological surface surveys. Each fragment was analyzed by Electron Micro Probe Analyzer coupled with an Energy Dispersive X-Ray System (EMPA-EDS) and by Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS) to obtain the composition of major, minor and trace elements. Surface analyses revealed the presence of corrosion layers in most of the glass fragments which was evident also in the chemical data. Nevertheless, reconstruction of the glassmaking processes and the approximate period of production was possible for almost all the glass fragments. Less than half of the examined fragments are attributable to recognizable typologies as unguentaria, beakers, bottles, and vases; all the other small fragments are typologically undetermined. Out of 17 fragments only one fragment is of HLLA composition possibly being produced in 17 th –18 th century AD, while all the others can be attributed to soda glass with different periods of production: natron glass from Roman and Early Medieval period, plant-ash glass from High or Late Medieval period with the exception of possible Byzantine glass from 6th century AD, and synthetic soda glasses typical of modern era. These data confirm the discontinuous habitation of the island from the Roman period as well as the import of glass objects to the island.

通过古代玻璃来证明人类对一个小岛的占领:Ustica案(意大利巴勒莫)

这项研究的主题包括从当地博物馆获得的来自乌斯蒂卡岛(意大利巴勒莫)的17个古代玻璃碎片。由于通过考古表面调查收集了全部17个玻璃碎片,因此它们在地层上都没有相关性。通过电子微探针分析仪,能量色散X射线系统(EMPA-EDS)和激光烧蚀-电感耦合等离子体质谱法(LA-ICP-MS)分析每个碎片,以获得主要,次要和主要成分。微量元素。表面分析表明,大多数玻璃碎片中都存在腐蚀层,这在化学数据中也很明显。尽管如此,几乎所有的玻璃碎片都可以进行玻璃制造工艺的改造和大约的生产周期。不到一半的检测碎片归因于可识别的类型,如菊苣,烧杯,瓶子和花瓶。所有其他小片段在类型上都不确定。在17个碎片中,只有一个碎片是HLLA成分,可能是在公元17至18世纪生产的,而所有其他碎片都可以归因于不同生产时期的苏打玻璃:来自罗马和中世纪早期的Natron玻璃,中世纪时期或晚期的烟灰玻璃,可能是公元6世纪的拜占庭玻璃和现代典型的合成苏打玻璃。这些数据证实了罗马时期该岛的不连续居住以及向该岛的玻璃制品进口。所有其他小片段在类型上都不确定。在17个碎片中,只有一个碎片是HLLA成分,可能是在公元17至18世纪生产的,而所有其他碎片都可以归因于不同生产时期的苏打玻璃:来自罗马和中世纪早期的Natron玻璃,中世纪时期或晚期的烟灰玻璃,可能是公元6世纪的拜占庭玻璃和现代典型的合成苏打玻璃。这些数据证实了罗马时期该岛的不连续居住以及向该岛的玻璃制品进口。所有其他小片段在类型上都不确定。在17个碎片中,只有一个碎片是HLLA成分,可能是在公元17至18世纪生产的,而所有其他碎片都可以归因于不同生产时期的苏打玻璃:来自罗马和中世纪早期的Natron玻璃,中世纪时期或晚期的烟灰玻璃,可能是公元6世纪的拜占庭玻璃和现代典型的合成苏打玻璃。这些数据证实了罗马时期该岛的不连续居住以及向该岛的玻璃制品进口。罗马和中世纪早期的纳腾玻璃,中世纪晚期的植物灰玻璃(公元6世纪可能的拜占庭玻璃除外)和现代典型的合成苏打玻璃除外。这些数据证实了罗马时期该岛的不连续居住以及向该岛的玻璃制品进口。罗马和中世纪早期的纳腾玻璃,中世纪晚期的植物灰玻璃(公元6世纪可能的拜占庭玻璃除外)和现代典型的合成苏打玻璃除外。这些数据证实了罗马时期该岛的不连续居住以及向该岛的玻璃制品进口。
