“…Corning C and D were used by Kuisma-Kursula [ 36 , 37 ] to determine the accuracy of the measurements. Bronk and Freestone [ 38 ] validated the usefulness of the scanning electron microscopy/energy-dispersive X-ray analysis in analyzing glass objects with the use of Corning A and B. They described the influence of the procedure used for the preparation of the Corning glasses to the final results and reported problems with quantification of some oxides (Sb 2 O 5 , PbO in Corning B).…”

Corning archeological reference glasses A, B, C, and D have been made to simulate different historic technologies of glass production and are used as standards in historic glass investigations. In this work, nanoseconds (193, 266 nm) and femtosecond (800 nm) laser ablation were used to study the elemental composition of Corning glasses using laser ablation inductively coupled plasma mass spectrometry. The determined concentrations of 26 oxides (Li2O, B2O3, Na2O, MgO, Al2O3, SiO2, P2O5, K2O, CaO, TiO2, V2O5, Cr2O3, MnO, Fe2O3, CoO, NiO, CuO, ZnO, Rb2O, SrO, ZrO2, SnO2, Sb2O5, BaO, PbO, Bi2O3) are compared with values reported in the literature. Results show variable discrepancies between the data, with the largest differences found for Cr2O3 in Corning A; Li2O, B2O3, and Cr2O3 in Corning B; and MnO, Sb2O5, Cr2O3, and Bi2O3 in Corning C. The best agreement between the measured and literature values was found for Corning D. However, even for this reference, glass re-evaluation of the data was necessary and new values for PbO, BaO, and Bi2O3 are proposed.FigureThe results of Corning glasses obtained by LA-ICP-MS after ablation by different laser wavelenghts presented as the ratios of the measured to the recommended values

“…However, various published articles reported some discrepancies between their measured analyses of some elements in the Corning glasses and the published recommended compositions (including KuismaKursula and Räisänen, 1999;Kuisma-Kursula, 2000;Bronk and Freestone, 2001;Falcone et al, 2002;Vicenzi et al, 2002;Shortland et al, 2007;Dussubieux et al, 2008;Wagner et al, 2008;Dussubieux et al, 2009). This prompted the study by Wagner et al (2012) with the purpose of testing the published recommended compositions of the Corning glasses and where needed, suggesting new values for some elements.…”

The Corning Archaeological Reference Glasses are widely used as standards in the chemical analysis of archaeological and historical glasses, as their compositions were designed to approximate those of major glass types in antiquity. Since their development in the 1960s, their compositions have been revisited and updated. This paper provides a brief overview of the Corning glasses, and addresses two of the last three elements to be re-evaluated: the recommended values for the concentrations of SO 3 and Cl were, until now, based on theoretical values. Data for these elements were collected using electron microprobe, and used together with published data to suggest new values. Finally, a complete list with the most up-to-date compositions for the four Corning glasses is compiled for the benefit of other analysts.

“…This glass was designed to match the compositions of ancient plant ash glass (Verità et al 1994;Brill 1999, vol. 2, p. 544;Bronk and Freestone 2001;Vicenzi et al 2002;Dussubieux et al 2009). Corning B is mainly used to calculate response coefficient factors for sodium, magnesium, aluminium, potassium, calcium, titanium, manganese, iron, strontium and barium.…”

A large analytical programme involving both obsidian source characterization and obsidian artefact sourcing was initiated recently within the framework of the French archaeological mission ‘Caucasus’. The results will be presented in two parts: the first part, this paper, deals with the presentation and characterization of obsidian outcrops in the southern Caucasus, while the second presents some results obtained from a selection of artefacts originating from different Armenian sites dated to between the Upper Palaeolithic and the Late Bronze Age. The same analytical method, LA–ICP–MS (laser ablation inductively coupled plasma mass spectrometry), has been used to characterize all the studied samples (both geological and archaeological). This method is more and more widely used to determine the elemental composition of obsidian artefacts, as it causes minimal damage to the studied objects. We present in this first part new geochemical analyses on geological obsidians originating from the southern Caucasus (Armenia, Georgia) and eastern Turkey. These data enhance our knowledge of the obsidian sources in these regions. A simple methodology, based on the use of three diagrams, is proposed to easily differentiate the deposits and to study the early exploitation of this material in the southern Caucasus.
