In this study, synchrotron radiation was used explore the relationship between degradation of some historical glasses of different provenance and dating and the oxidation state of their colouring agents. tje oxidation states of copper in red and green glasses were monitored by recording spectra at the Cu K-edge by X-ray absorption near edge structure Promissing results with this new analytical tool may extend knowledge about glass decay.
