Mycenaean glass from the Argolid, Peloponnese, Greece: A technological and provenance study

The study resulted in the chemical fingerprinting of the collection with the use of the totally non-invasive techniques of Optical Microscopy (OM), X-Ray Fluorescence (XRF), Prompt Gamma Activation Analysis (PGAA) and Scanning Electron Microscopy coupled with an Energy Dispersive X-Ray Analyser - (SEM/EDS) in quasi invasive mode. The statistical analyses provided technological evidence for compositional similarities among the samples that form two major compositional groups, with at least the one associated with artifacts originating from Egypt. Regarding their coloration at least two cobalt colorants can be identified with respect to the cobalt-associated impurities.
