Studies on historical glass

During the last decade and more, our research group has become experienced in various research topics in the broad field of studies on historical glass. Firstly, by determining the exact composition of major and trace elements in historical glass fragments information can be retrieved concerning not only the provenance of the glass itself, but also of the raw materials used for its synthesis. This allows us to draw conclusions on the glass production as well, which is checked by performing glass synthesis experiments via known historical recipes. Secondly, glass degradation phenomena are studied and more specifically possible changes in oxidation state of colourising/decolourising elements present in historical glass.
