Portable energy-dispersive micro x-ray fluorescence spectrometry (formula) is a useful device for non-destructive chemical analysis of different materials. Despite its evident potential in the fields of glass analysis, only few archaeometric studies have been performed yet. In this work, preliminary results on the analysis of different types of industrial glass by XRF are presented in view to apply this method in industrial applications (monitoring of glass cullet, production quality control, classification of end products, etc). The experiential results show a reliable qualitative recognition of detectible element in the glass. A good correlation line intensity/concentration was verified for several important elements. furthermore very low limits of detection were estimated for critical elements such as Fe, Cr and Pb.
