Archeometrical analysis of glass of western Emilia Romagna (Italy) from the imperial age.

Recent studies have allowed a typological and chronological characterization of Roman glass dated from the 1st to the 4th century AD. The samples have beenwere recovered from several archaeological sites during a surface survey on the plain South south of the river Po, which was a crucial transit area both via land and river. The chemical composition of 79 glass fragments of different typology was obtained by WDS-XRF and EMPA. The results were treated with hierarchical agglomerative cluster analysis. All the analysed samples resulted Silica-Soda-Lime glass. The differences in the chemical composition were mainly related to the colour and the age of the samples, whereas no relation was found with artefact typology or site of the find. The chemical composition of Padana plain glass was compared with literature data for samples of the same period coming from Aosta and Aquileia.
