 abstract={Modern archaeological research uses physico-chemical methods to answer questions beyond the scope of the conventional historian’s workshop. This applies to research on the borderline of fields, including material research into the elemental and isotopic composition of artefacts. The results of such analyses make it possible to address issues relating to the distribution of raw materials and the technology of artefact production. The paper discusses the SEM-EDS and LA-ICP-QMS micro-analysis methodology, addressing the limitations that result from the specification of techniques and the state of preservation of archaeological artefacts due to corrosion processes and conservation treatment. We present the preliminary results of technological research and provenance study of early medieval objects made of silver alloys, considered by typological group, i.e. coins, cake, and jewellery. Two hundred objects were analysed, revealing clear evidence for the use of remelted dirhams as the main source of raw material. The results of the research allowed for a material description of the phenomenon of the existence of cores in cross denarii, distinguishing two types of cores: based on copper and brass. In the case of jewellery, the research provided evidence for technological distinction, indicating the use of copper-based solders, as well as tin- and lead-based dolders, which have analogies in goldsmithing material from the Czech Republic. Recipes based on the marked composition are described in ancient sources. Silver cakes, on the other hand, can be divided into three extraction groups related to the degree of purification of the raw material. The preliminary results indicate that these objects were made of Asian dirhams and native lead, perhaps as an additive in the cupellation process.},
