Chemical and Oxygen Isotopic Composition of Roman and Late Antique Glass from Northern Greece

Table 4

Isotopic and chemical composition of Roman and late Antique glasses from Thessaloniki, 1st–6th centuries AD in age. Samples with moderate and strong ¹⁸O enrichment are in italics and bold font, respectively. Note that NiO, ZnO, and SnO₂ contents are not reported because they are lower than EMPA detection limits for all samples (LOD of NiO = 0.03 wt%; LOD of ZnO and SnO₂ = 0.04 wt%).
