Division of IZT-1 and IZT-2 samples and comparison with key primary glass reference groups of the first millennium CE. Egyptian reference groups shown in orange and Levantine in blue. Note that even though IZT-1 samples plot in Roman-Sb, their Hf isotopic values exclude an Egyptian origin. Reference data sources include 37,38,39,40,43,51,58.
