The aims of this study were to characterize corrosion effects on Mycenaean glass objects and their implications for provenance studies. Investigations of archaeological glass collections from Greek 16th -13th c. B. C. Late Bronze Age sites in North-East Peloponnese, Palaia Epidavros and Ancient Asine in the Argolid and from Pylos in Messenia, South Peloponnese have been performed. The study was prompted by specific archaeological questions: whether the glass artifacts were imported as ingots and/or previously shaped materials via exchange roots or they were produced in local glassmaking workshops. Optical microscopy was employed for an initial morphological examination, followed by Scanning Electron Microscopy coupled with an Energy Dispersive Analyser (SEM-EDS) and by X-ray Fluorescence (XRF) Analysis. The general trend was found to be in agreement with the existent knowledge about altered glass, that is, severe alkaline, alkaline earths and silica deviations. For the bulk analytical examination, Prompt Gamma Activation Analysis was applied. Based on the bulk PGAA results, it was possible to differentiate between base glass used for the production of the Argolid samples and that used for the production of the Messene samples. Also, possibly more than one recipes of alkaline source have been used for the production of the Argolid samples.
