Stained glasses from Monastery of Batalha: Non-destructive characterisation of glasses and glass paintings

The combination of the different analyses on the different glass samples allowed knowing the composition of the glasses and glass paintings. Using UV-vis spectroscopy, both the oxidation state of an element and its coordination, which are responsible for the colours displayed, could be determined. The presence and distribution of silver and copper in glass surfaces painted with yellow silver stain were also studied.
