Glass Conservation Evening: ‘The Remarkable People, Places and Processes of Stained Glass Windows’

Date: Wednesday 14th September 2023 | 6-8pm
Location: St Botolph’s Aldgate, Aldgate High Street, London EC3N 1AB

Join two experts on stained glass, Leonie Seliger and Alexandra Epps, for an evening that looks in on the making and conservation of stained glass and lets the light in on the relevance of the stained glass windows in Wren’s churches.

Discover how stained glass windows are actually made, gain an appreciation of the very labour-intensive manufacturing processes involved, including creating a cartoon from a design, cutting the glass, painting, staining, acid-etching, firing, leading and finally installing the finished panels. Then find out how windows age, what to worry about and what perhaps not, and the different ways there are to address the conservation/restoration of historic stained glass. Leonie will give some examples of the good, the bad, and the ugly!

Following the devastation of wartime bombing a remarkable generation of architects, artists and craftsmen emerged to recreate the churches of the City of London in the spirit of Sir Christopher Wren. Let Alexandra introduce you to Christopher Webb, Brian Thomas, Lawrence Lee and other notable professionals, and learn about the meaning embedded in the windows and the style of windows. Discover the identity of the City – unique stories of people, time and place – all expressed within the fascinating post-war stained glass to be found in many of Wren’s historic churches.

Question time, wine reception and networking will follow at the conclusion of the talks.
