Fig. 4: Trace element characteristics for Tell Iẓṭabba glass groups.
From: The Hellenistic - Roman transition in glass technology: insights from Nysa-Scythopolis
Mean concentrations of trace elements within the Tell Iẓṭabba subgroups IZT-1B and IZT-1C and main group IZT-2 normalised to mean concentrations for subgroup IZT-1A. Note that high Cr concentration (53 ppm) for sample Tell Iz-1 was excluded from the average of IZT-2 glasses. Data from Supplementary Data 1.
