Abstract

In this study, we have evaluated the applicability of Nd isotopic analysis for the provenancing of Roman glass and we present a database of Nd isotopic compositions of possible sand raw materials from the western Mediterranean, as a means of comparison for the growing number of isotopic studies on ancient glass. The 143Nd/144Nd isotope ratio of sands is a good indicator for their geological (and sometimes geographical) provenance. The use of the isotopic signature of Nd as a proxy for the source of silica in glass is, however, not always straightforward because of the possible overlap of signatures from different suppliers. ispartof: Archaeometry vol:55 issue:3 pages:449-464 status: published

Abstract

The provenancing of Roman natron glass is one of the most challenging problems in the field of archaeometry. Although the use of Sr and Nd isotope ratios and trace element signatures as an indication of provenance has proven promising, there are still many unknowns. In this study, the influence of the different raw materials on the final Sr isotopic composition of Roman natron glass is examined. It is shown that the 87Sr/86Sr ratio in natron glass is significantly influenced by the silicate fraction of the sand used and does not always provide a clear indication of the lime source used.

Abstract

In this study analysis of major elements and Sr--Nd isotopes is performed on 33 colourless glass fragments from two Ro- man shipwrecks discovered in the Northern Mediterranean Sea, the Iulia Felix (irst half of the third century AD) and the Ouest-Embiez (end of the second--beginning of the third century AD). Two compositional groups are deined based upon the major elements analysis, suggesting the use of diferent raw materials, and possibly the production of the glass samples in two separate factories. Sr--Nd isotopes, promising indicators for provenancing geological resources used as raw materials 87 86 in glass manufacturing, conirm the compositional groups. The Sr/ Sr signature is very close to the modern sea water signature (0·7092) for all samples, likely due to the use of shell as glass raw material. The Nd signature further subdivides the compositional groups, suggesting the use of three diferent sand raw materials for the production of glass. [ABSTRACT FROM AUTHOR]
