A representative group of seal dies made of copper alloys from the collection of the National Museum of Slovenia was investigated by energy‐dispersive X‐ray fluorescence spectrometry (EDXRF). Chronologically, the artefacts date from the early 13th century to the present. Non‐destructive EDXRF screening of elemental fingerprints of Cu, Zn, Pb, Ag, Sn and Sb was performed on 95 seal dies, and the obtained elemental data set was further processed by chemometric tools such as principal component analysis (PCA). The relationships between the elemental composition of analysed seal dies, type of alloy applied and their historical context—date, location of manufacture and, possibly, social rank of the owner—were examined in detail.

斯洛文尼亚国家博物馆的印章模具：中世纪和早期现代铜合金的无损分析

通过能量色散X射线荧光光谱法（EDXRF）对来自斯洛文尼亚国家博物馆收藏品中的一组代表性的由铜合金制成的密封模具进行了研究。按时间顺序排列，文物可追溯到13世纪初期到现在。在95个密封模上对Cu，Zn，Pb，Ag，Sn和Sb的元素指纹进行无损EDXRF筛选，并通过化学计量工具（例如主成分分析（PCA））对获得的元素数据集进行进一步处理。详细检查了所分析的密封模具的元素组成，所用合金的类型及其历史背景（日期，制造地点以及可能的所有者社会地位）之间的关系。
