This article presents an archaeometrical research carried out on twenty-six vitreous finds collected in the Cosenza Cathedral (Calabria, Italy). The glasses have been subdivided in two typo-chronological groups. The first group is composed of 14 vitreous samples dating to the 4 th –6 th century AD. The second group includes twelve samples; seven are stems of funnel-shaped hanging lamps which date between the 12 th and the 13th century AD, two are bottlenecks of balsamaria and three are concave bases. The aims of this study were the determination of the chemical composition of vitreous finds and the individuation of the primary glass sources. The samples were characterized through Electron Probe Micro Analyser with Wavelength Dispersive Spectrometer (EPMA-WDS) and Laser Ablation with Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). The data confirm that all the finds of the first group are “silica-soda-lime” type glasses characterized by a high content of Na 2 O and a low content of K 2 O and MgO. On the contrary, the samples of the second group, showing higher contents of K 2 O and MgO, are vegetable silica-soda-lime glasses. Their composition confirms the typological attribution to the medieval period.

结合使用分析技术，从科森扎大教堂（意大利卡拉贝里亚）得到的玻璃发现物的化学表征

本文介绍了对在Cosenza大教堂（意大利卡拉贝里亚）中收集的26个玻璃质发现物进行的考古学研究。眼镜已分为两个按时间顺序排列的类别。第一组由14个玻璃样样品组成，可追溯到公元4-6世纪。第二组包括十二个样本。七个是漏斗形吊灯的茎，可追溯到公元12至13世纪，两个是香脂的瓶颈，三个是凹形的底座。这项研究的目的是确定玻璃碎片的化学成分和主要玻璃来源的个性化。通过具有波长色散仪的电子探针微分析仪（EPMA-WDS）和电感耦合等离子体质谱仪的激光消融（LA-ICP-MS）对样品进行表征。数据证实，第一组的所有发现物均为“硅酸钠石灰”型玻璃，其特征在于Na 2 O含量高而K 2 O和MgO含量低。相反，显示出较高的K 2 O和MgO含量的第二组样品是植物二氧化硅-钠钙玻璃。它们的组成证实了中世纪时期的类型学归因。
