A set of colored glass tesserae (yellow, blue turquoise and green turquoise) discovered at Isaccea and dated to the 11th century AD was investigated using Ion Beam Analysis (IBA) techniques to determine their chemical composition. Particular attention was paid to identify the glass chromophores and opacifiers. Based on the analytical results, several conclusions about the way these archaeological finds were manufactured, particularly on the raw materials and employed techniques were deduced. © 2016, Editura Academiei Romane.

This paper reports the particle induced X-ray emission (PIXE) and particle induced gamma-ray emission (PIGE) analyses of 78 glass bracelet fragments discovered in the Byzantine fortified settlement of Isaccea, Romania (10th–13th centuries AD). The chemical composition of the glass was used to identify the raw materials and manufacturing techniques. Most of the bracelets turned out to be soda-lime-silica glasses, but lead and soda-lime-lead glasses were also identified. The PIXE–PIGE data revealed the glass chromophores and provided clues about the pigments used to decorate the external surfaces of some bracelets—lead stannate and gold alloy. The analytical results showed that the bracelets were manufactured by recycling different types of coloured glass, probably in a local workshop. © 2015, Akadémiai Kiadó, Budapest, Hungary.
