Investigations of Byzantine glass bracelets from Nufaru, Romania using external PIXE-PIGE methods
Bugoi, R.; Poll, I.; Manucu-Adamesteanu, G.; Neelmeijer, C.; Eder, F.;
The chemical composition of 20 glass bracelet fragments found in Nufaru, a Byzantine site from 10th - 13th centuries A.D., nowadays located on Romania's territory, has been determined using Particle Induced X-ray Emission (PIXE) and Particle Induced Gamma-ray Emission (PIGE) in external beam mode. Most of the Byzantine bracelet fragments were identified as "mixed natron-plant ash" soda-lime-silica glasses. The obtained chemical compositions indicated that the manufacturing of these finery items was performed using similar raw materials and techniques, in most of the cases involving colored glass recycling. PIXE-PIGE results highlighted the glass chromophores (cobalt, manganese, copper and iron ions) and provided hints about the mineral pigments used to paint the external surface of some bracelets.
