Abstract

Glass tesserae belonging to decayed and lost part of the mosaic floors of the Basilica Alpha of Nikopolis in Epirus have been analysed, determining their chemical composition and the possible presence of crystalline phases. As in all glasses produced in the Mediterranean area in that epoch, they are soda-lime silicatic glasses, in part with lead, obtained using natron as a flux. The typology of the glass corresponds to that of the Roman glasses, of the first centuries A.D., and it is the same employed for the basilicas of Ravenna in the fifth and sixth centuries; in particular, the comparison has been carried out with the glass tesserae of the St Vitale Basilica. Also the technological base for producing coloured glasses is practically he same of the mosaic glasses of Ravenna.
