Abstract

This work is aimed to the study of a series of Late Roman glass fragments belonging to the peculiar group called HIMT (High Iron Magnesium Titanium glass), characterized by different color nuances, and previously chemically characterized by our group. XANES, UV-VIS and luminescence spectroscopies are exploited for determining the distribution of the oxidation states ofthe two chromophores Fe and Mn. In all the ancient glass samples, Fe results to be mostly in its oxidate state 3+. The prevalent Mn oxidation state is 2+, however the presence of minor amounts of Mn3+ has been proved. The different spectroscopic techniques, used in a combined approach, areable to interpret the apparent anomalous colour of some of the ancient glass samples.
