|Abstract: ||Glass is one of the ancient human products most often traded for long distances from the place of raw material
supply. Provenance studies on this kind of artefact are mainly based on the comparison of major and trace elements
among archaeological samples.
The paper proposes a step-by-step geochemical organized protocol that considers the elements with prominent
influence on glass composition, helping in a fine discrimination of compositional groups and, consequently, an
easier identification of provenance in archaeological artefacts. The proposed approach is presented through the
case study of Roman blue glass samples, dated from the 1st century to Late Antiquity and coming from the
Palatine Northeast archaeological site. Optical Microscopy, SEM-EDS, EMPA and LA-ICP-MS results are discussed
to gather information on network former, flux, colourants and decolourants. In addition, the comparison with
literature provides additional information on chemical groups of ancient glass spanning from the 1st to the 5th
