Thirty six glass items excavated at Cârlomăneşti and Pietroasa Mică, Buzău County, Romania (3rd c. BC – 1st c. AD) were analysed for their chemical composition using external PIXE-PIGE at AGLAE accelerator, Paris and external PIXE at the 3 MV Tandetron™ accelerator, Măgurele, to reveal the raw materials and manufacturing procedures, trying to reconstruct the links between the Geto-Dacian populations and the Hellenistic, Celtic and Roman ones during that historical time. The archaeological hypothesis was that these vitreous artefacts were luxury goods imported as such, made of fresh glass. The analyses showed that the objects were shaped from natron glass, with recipes typical for the Hellenistic period. Occasionally, glass recycling indicators were evidenced. Hints about the decolorizers (antimony, manganese) or chromophores (manganese, iron, cobalt, copper) were obtained. This archaeometric study is a pioneering one, considering the absence from the literature of compositional data on glass finds discovered in Geto-Dacian settlements.
