MgO versus A. Al2O3 (wt%) B. Ti (ppm) and C. FeO (wt%) showing the differences between the two glass types at Tell Iẓṭabba illustrated by relatively elevated concentrations of MgO, Al2O3, FeO and Ti observed for IZT-2 relative to IZT-1 samples. D. 87Sr/86Sr versus εHf showing the lower 87Sr/86Sr ratios at a given εHf value for IZT-2 glasses. For 87Sr/86Sr - εHf plot, data points are labelled with MnO concentrations showing that the different isotopic values observed for IZT-1 relative to IZT-2 samples are independent of added Mn decolouriser.
