Cardiff Archaeology and Conservation wins Leverhulme Funding

Corrosion, composition and origins of medieval stained glass A panel from the Great East Window of York Minster under conservation

To begin in October 2007, this project, a collaborative investigation with the Department of the History of Art at the University of York, will be funded by a research grant of £130,000 to Professor Ian Freestone from the Leverhulme Trust. It will focus on the glass of the Great East Window, York Minster, Europe’s largest single expanse of stained glass, which is currently undergoing conservation by York Glaziers Trust.

Ian says, “The dismounting of the East Window for conservation provides a unique opportunity to study a comprehensive assemblage of glass used by a single glazier, in this case John Thornton of Coventry. By comparison with glass from other windows by the same craftsman, we will gain crucial insights into the production and distribution of this important medium. Our stained glass heritage is under continual threat as the glass is unstable in the atmosphere and deteriorates quickly. The East Window can offer us important insights into these processes as it contains a wide range of glass colours, all of which have been subjected to essentially identical environmental conditions over the centuries.”
