Between manufacturing and trade: IBA analyses of archaeological glass finds discovered at two Dacian settlements: Sarmizegetusa Regia and Piroboridava

This publication reports the IBA results on 81 glass items discovered at Sarmizegetusa Regia (Grădiștea de Munte, Hunedoara County) and Piroboridava (Poiana, Galaţi County), Romania, dated to the 1st century CE. External beam PIXE-PIGE measurements with 3 MeV protons were performed at LABEC, INFN, Florence, Italy. The IBA data indicated strong similarities, in terms of chemical composition, with coeval Roman and Hellenistic finds, supporting two archaeological hypotheses: 1) raw glass was imported to Dacia from the Roman Empire and locally shaped into various finished products; and 2) glass vessels were also imported to the Dacian settlements.
