“…As is evident from Fig. 11a, b, the obtained data for the studied natron-based Si-Na-Ca and Si(Al)-Na-Ca glass beads (Table 2, 6) are very close in their chemical composition to published data aboud glass artifacts found in Pichvnari necropolis, Georgia (Shortland and Schroeder, 2009) and Methoni, Greece (Blomme et al, 2017). Moreover, comparing chemical analyzes, it was found that the chemical composition of opaque yellow bead 1181 (Table 2) almost completely matches the analyzes data of some glass artefacts found in Pichvnari necropolis, Georgia (Shortland and Schroeder, 2009, p. 955, samples Pic16b, Pic.21b and Pic28b) and Northern Italy (Arletti et al, 2009, pp.…”

“…In these charts, the beads are labelled not only by their lab codes but by their chemical types also. A comparison of analyzed samples and published data for glass artifacts from Apollonia Pontica necropolis in Bulgaria (Lyubomirova et al, 2014), Pichvnari necropolis in Georgia (Shortland and Schroeder, 2009), Pydna and Methoni in Pieria Greece (Blomme et al, 2017) and from Rhodes (Rehren et al, 2003) is given in Fig. 11.…”

The glass beads from the Dren-Delyan necropolis are found in burial complexes dated as from the end of the 6th century BC until the first half of the 4th century BC. The purpose of this study is to obtain data on the chemical composition of the glass and the technology of its production. LA-ICP-MS and SEM-EDS analyses were conducted. The analysed glass beads are classified as a low-magnesium type (LMG), and only one of the samples is determined as high-magnesium glass (HMG). The yellow colour of the glass is due to crystals of lead antimonate incorporated into the glass matrix. The green colour of the beads is a result of interaction of added copper and lead in the glass mixture, in presence of iron and chromium. Dark blue samples are coloured by additives with cobalt, copper and lower iron content. Light blue colouration of opaque glass beads is due to high copper content, along with the presence of iron. The colouring agent of a transparent light blue bead is FeO in amount up to 0.25 wt%. The brown colour is associated with high iron content. Two different opacifiers were used for the production of opaque glass beads – antimony and tin, either individually or together. The decolourising agent is antimony without the involvement of manganese. Based on the results of the studied glass beads, we assume at least four types of raw material mixtures for their production. Comparison of the obtained results and published data about similar ancient glass findings was made.

“…Different studies on the Mediterranean I, II and III glass groups produced between the sixth and the fourth centuries BCE bear witness to a fairly complex situation. Published results [14][15][16][17] show varying correlations between cobalt, iron, zinc, copper and nickel. These variations suggest either the contemporaneous exploitation of different cobalt-bearing ores or a small-scale exploitation process of a large cobalt mine with different types of cobalt ores, giving rise to a range of colorant compositions.…”

Changes in the Signature of Cobalt Colorants in Late Antique and Early Islamic Glass Production

2018

Prior to the eighteenth century, cobalt was exclusively employed as a colouring agent for vitreous materials, and its use appears to be concurrent with the earliest large-scale production of glass during the Late Bronze Age (LBA). LBA cobalt deposits with a distinctive elemental signature have been identified in the oases of the western Egyptian desert, while cobalt mines in Kashan (Iran) and in the Erzgebirge (Germany) are known to have been exploited during the later Middle Ages. For most of the first millennium BCE and CE, however, the identity of cobalt sources and their supply patterns remain elusive. The aim of this study is to characterise the chemical composition of cobalt colorants used during the first millennium CE. Compositional variations indicate the use of different raw materials and/or production processes, which in turn has implications for the underlying exchange networks. Using mainly correlations between cobalt, nickel and zinc as discriminants, our results show that the compositional signature of cobalt underwent two major changes. An increase in the CoO/NiO ratios occurs between the late fourth and the beginning of the sixth century, while a new zinc-rich source of cobalt begins to be exploited during the second half of the eighth century in the Islamic world.

“…Several recent studies have stressed that a multiple isotopic approach is most effective for the provenance of geological and biological materials. [6][7][8] Such methods, however, along with petrological studies of the constituent mineralogy, generally require grams of material, something that is impossible to obtain from museum-grade artefacts.…”
