“York Glaziers Trust are using the groundbreaking new restauro UV glass at York Minster to protect the Great East Window.  The window is one of the masterpieces of fifteenth-century glazing in Europe. Painted between 1405 and 1408, it is the largest single expanse of medieval glass in Britain. Work to conserve and restore the Great East Window is part of the York Minster Revealed project, which is due for completion in 2016.

York Minster will be the first building in the UK to use this revolutionary material to protect its ancient stained glass, and as Sarah Brown, Director of the York Glaziers Trust comments, "it is reassuring to know that we are now able to offer total environmental protection for all aspects of the conserved window."
Previous protective glazing has acted as a weather shield and kept glass, lead and conservation materials dry, but has not been an adequate barrier to Ultra Violet radiation. This impacts on any epoxy resin used in the conservation of the stained glass and leads to a yellowing discolouration of that resin after prolonged exposure.
Earlier forms of UV-resistant glass have relied on laminations of glass and a UV-resistant foil, but in the new restauro UV © glass, the UV resistance is an integral part of the glass itself. The product has been developed by Glasshuette Lamberts of Germany, the world-leading producer of mouth blown antique glass.  The protective glass is now being installed, and the York Glaziers Trust and their client, York Minster, are delighted with the beautiful traditional hand-crafted appearance of the glass, which is in perfect harmony with the surrounding medieval stonework.”
