Glass production in the Middle Ages from Italy to Central Europe: the contribution of archaeometry to the history of technology
The present paper reports and discusses data obtained by a combined archaeological and archaeometric study carried out on an assemblage of selected Medieval glass finds from the Monastery of St. Severus in Classe (Ravenna, Italy) and ascribable to the 13–16th CE. Glassware belonging to three main typological groups was selected for this study: ampoules, nuppenbecher and kropfflasche. Such a choice mainly stems from the intent to evaluate typological and compositional affinities of these peculiar vessel typologies with the same forms unearthed in different regions of Central Europe, as a starting point for a possible reconstruction of trade contacts between Italy and Central Europe. Archaeological contextualisation of the site and chrono-typological study of glass vessels were associated to ICP-MS (inductively coupled plasma mass spectrometry) and ICP-OES (inductively coupled plasma optical emission spectrometry) analyses, performed to characterise the composition of the glassy matrix (major and minor components as well as trace elements). The results, elaborated according to the archaeometric glass classification and provenancing of raw materials, shed new light on glass production in late Medieval times and can be broaden framed as a starting point for interpreting relations and exchanges between geographical areas and related cultures
