Abstract The oxidation states of colouring elements and the pigments in ancient rare glasses have been investigated in this study. Synchrotron X-ray, SEM-EDS, and Raman techniques revealed that Cu2+plays a major role in blue and green glasses. The lead stannate pigment gives glasses a yellow colour. Copper and lead stannate can cause the green colour in glasses, and iron gives rise to the colour of black glasses. Microcomputed tomography reveals the distribution of the heavy elements, pigments, and inclusions in the glasses. The Dvaravati glasses in Southeast Asia may have been imported or technologically transferred to domestic manufacturers during trading on the Silk Road that connected the East and the West.

When compared with contemporary Germanic settlements, the assemblage of beads from the late antique elite residence at Cífer-Pác (Trnava district) is exceptional not only in the number of individual specimens but also in the variability of forms and materials used. Apart from usual types of glass beads, the assemblage also comprised specimens made from rare materials (marble, carnelian) and materials that appear exotic in the barbarian territory north of the Danube (sea coral, jade). They were identified with the help of natural scientific analyses and gemological methods (Raman spectroscopy). Absorption spectroscopy was used to analyse elements that influence the final glass colour.
