Аннотация:In 2017, the archeological expedition of the Institute of Archeology RAS, supervised by Galina V. Trebeleva, discovered glass beads at a burial site of the Roman period at the Markul settlement in the Republic of Abkhazia. The objective of this study is to determine the origin of the discovered artifacts. To achieve this, various analytical methods were employed to determine the chemical composition of ancient glass. The findings were studied using two analytical meth-ods: microanalysis with scanning electron microscopy (for five items) and mass spectrometry with inductively coupled plasma and sampling by laser ablation (for 14 items). The results were interpreted according to the methodology proposed by Yulia L. Shchapova and were later supplemented by Teresa Stawiarska. The analysis revealed that most of the glass samples (13) had a composition based on natron, which is a characteristic of the Roman glassmaking school. Four items were made using plant ash, which is a characteristic of the Middle Eastern school of glassmaking. One bead was tentatively attributed to a jet because it was found not to be glass. The carnelian pendant was examined and was found to have a silver lug/fastening.
