What's Wrong with My Windows?

Care and Conservation of Historic Glazing [WS2]

(Based on Track 4—Traditional Building Practice in the 21st Century: Preservation Renewal and a Future Based on Past Experience)

Many of our significant architectural buildings are glazed with leaded and decorative stained glass, from historic homes to monumental cathedrals. Stained and decorative glass windows are unique in that they are part of the exterior and interior of the buildings in which they are installed. These windows are often subjected to the forces of climate, time, inherent vice and vandalism. It is imperative that we preserve these fragile great works and of art for cultural, artistic and historical reasons.

This two-day workshop will define what leaded and decorative stained glass are, as well as develop your understanding of what can go wrong with them and the most appropriate means and methods to employ for their conservation and preservation. In addition to hands-on work, participants will perform a conditional assessment on the windows of a local historic church. This workshop is sponsored by the APT Technical Committee on Preservation Engineering.

  • Arthur J. Femenella, Femenella & Associates, Inc, Branchburg, NJ, USA. Mr. Femenella began training in stained glass in 1968 and apprenticed to the Greenland Studio of New York from 1972 to 1975. He eventually served as vice-president of Greenland and later Jack Cushen Studio of New York, and both studios gained international recognition for excellence in the field of stained glass conservation.  Mr. Femenella has been responsible for the restoration of thousands of windows, doors, panels and artifacts, including hundreds of works by John La Farge, Louis Comfort Tiffany, Frank Lloyd Wright, Maitland Armstrong, Mary Tillinghast and other artists of equal importance. Mr. Femenella was the primary author of the booklet Standards and Guidelines for the Preservation of Historic Stained Glass Windows.  Mr. Femenella sat on the Board of Governors of the Census of Stained Glass Windows in America, and was the primary author of the technical section of The Conservation of Historic Stained Glass: An Owner's Guide.  He is a member of the National Trust for Historic Preservation and a member of the British Society of Master Glass Painters. 
  • Mr. H. Thomas Küpper, MA, ACR, Lincoln Cathedral, Works Department, Lincoln, Great Britain, UK. In 1989, H. Thomas Küpper attended a summer school in stained glass whilst living in the Lake District in the North West of England, and soon found himself busy making leaded lights and coloured glass windows for the domestic market, including restoring 19th and 20th Century ecclesiastical stained glass windows for local parish churches.  In 2001, Mr. Küpper gained his Post Graduate Diploma from DeMontfort University in the conservation of Historic Objects.  Two years later he completed an MA in the same studies, writing his dissertation examining the effects of manganese browning on medieval glass.  Since 1999 he has been Team Leader of the Lincoln Cathedral Glazing Department, heading a team of conservators and craftspeople restoring the historical windows of the cathedral and in the diocese.  He is involved in vocational training and education and has presented a number of professional papers in Britain and the USA on conservation related topics.
