The study provides a detailed investigation into several representatives of La Tène jewellery. Primarily, it deals with non-metallic decorative inlays from the Late La Tène period, particularly with their application on a metal base. Unique artefacts have been selected for the study, all coming from the Czech Republic and Slovakia. A prime representative of the finds is a torc coming from a La Tène burial site in Prague (Czech Republic, Central Europe). In this geographical context, such finds are rather exceptional. The torc examined is remarkable both in terms of its origin and the production technology utilised, namely the application of decorative inlays made of red opaque glass. Available literature classifies this decorative element as an enamel technique. The highly specific type of red soda high-lead glass applied there was examined using LA-ICP-MS. Based on the trace elements detected, it can be established that the glass is most likely related to contemporary Egyptian production. Other items of the artefact set consist of two Münsingen brooches from Moravia and an exceptional brooch from Slovakia. The latter find was found to be decorated with coral (as confirmed by Raman spectroscopy). Besides identifying the materials of the decorations, we were also able to characterize the binder between individual decorative inlays and their metal base. The analysis of the binder has revealed the presence of birch tar (determined by FTIR and GC/MS). The results obtained expand the knowledge about the production technologies applied to the jewellery from the La Tène period.

该研究对 La Tène 珠宝的几款代表进行了详细调查。它主要涉及拉特内时期晚期的非金属装饰镶嵌物，特别是它们在金属底座上的应用。该研究选择了独特的文物，全部来自捷克共和国和斯洛伐克。这些发现的主要代表是来自布拉格（捷克共和国，中欧）拉泰内墓地的一个环。在这样的地理背景下，这样的发现是相当特殊的。所检查的圆环在其起源和所使用的生产技术方面都非常引人注目，即由红色不透明玻璃制成的装饰性镶嵌物的应用。现有文献将这种装饰元素归类为珐琅技术。使用 LA-ICP-MS 对应用的高度特定类型的红钠高铅玻璃进行了检查。根据检测到的微量元素，可以确定该玻璃很可能与当代埃及的生产有关。该文物套装的其他物品包括两枚来自摩拉维亚的Münsingen 胸针和一枚来自斯洛伐克的精美胸针。后一个发现被发现装饰有珊瑚（拉曼光谱证实）。除了识别装饰品的材料之外，我们还能够表征各个装饰镶嵌物与其金属底座之间的粘合剂。对粘合剂的分析表明存在桦木焦油（通过 FTIR 和 GC/MS 测定）。获得的结果扩展了有关拉特内时期珠宝生产技术的知识。
