“…Sr in natron glass is mostly derived from the shell or limestone introduced (whether or not deliberately) as the source of lime (Wedepohl and Baumann, 2000;Freestone et al, 2003;Brems et al, 2013a). High Sr concentrations in glass suggest the use of shell fragments, while low Sr contents indicate the use of limestone.…”

“…B, P and U are partly derived from the silica source (Shortland et al, 2007), but they also come in with the natron flux. Sr is provided by both the sand (i.e., mostly feldspar and mica) and the source of lime (Brems et al, 2013a). In Mn-rich glasses, some of the Sr may be introduced through the Mn ore (Ganio et al, 2012b, c).…”

“…Sand raw material IT85 can be easily distinguished from Belus River sand by its higher TiO 2 , Cr and Zr contents, and lower Sr. Sand IT85 has 87 Sr/ 86 Sr isotope ratios higher than the modern seawater value, while Egyptian glass has relatively low Sr isotopic signatures (Freestone et al, 2003;Brems et al, 2013a;Fig. 4…”

Archaeological and archaeometric study of the glass finds from the ancient harbour of Classe (Ravenna- Italy): new evidence

et al. 2015

Introduction: The present study focuses on Late-Roman/Early Medieval glass found in the productive area within the ancient harbour of Classe near Ravenna, one of the most important trade centres between the 5 th and 8 th centuries AD of the Northern Adriatic area. Aims of the study were the identification of the main glass compositions and their contextualisation in Late-Antique groups; the identification of provenance of raw glass, and, consequently, of commercial routes; the extent, if any, of recycling glass cullet, as an alternative to the import of fresh raw glass; the identification of possible connections between archaeological typology and glass chemical composition.Results: 32 glassworking wastes and 25 drinking vessel fragments for a total amount of 57 fragments were devoted to chemical analysis in XRF and EPMA. All the analysed fragments are silica-soda lime glasses, produced with natron as a flux, and are compositionally similar to Late-Antique groups HIMT, Série 3.2 and Levantine1. Raw glass chunks, glassworking wastes and objects of comparable compositions are identified into HIMT and Série 3.2 groups, while the Levantine 1 group includes only objects and glassworking wastes. Systematic comparisons between Classe and Aquileia, the two most important Late-Antique archaeological sites of North-Eastern Italy, were also carried out, and the same compositional groups were identified, although Série 3.2 in the Classe assemblage is more represented. Sr and Nd isotopic analysis confirmed that the composition of the three glasses derive from coastal sands of the Syro-Palestinian and Egyptian shore, with a slight shift in comparison to the published data. Little evidence of recycling was identified in the assemblage. Conclusions:In the 5 th century, a secondary glass workshop devoted to the shaping of glass vessels starting from raw glass chunks and, possibly, glass cullet, was active in the area of the harbour. Raw glass of HIMT and Série 3.2 was imported from the Levant and Egypt. Comparisons between Classe and Aquileia show that during the Late Antiquity these sites seem to be supplied of raw glass by the same trade routes. In addition, some connections between types and chemical compositions were highlighted.
