West Point stained glass panels
These panels were taken apart, cleaned and recamed (the lead between the individual pieces of glass were replaced). Seldom does this need to be done. It is a very expensive process. There are tests that can determine if the lead came needs to be replaced. Usually the stained glass panel can be restored in place.

The process of repairing these stained glass panels requires that the craftsmen not only restore historical artifacts but also that they record history.

Church Restoration

Even before the windows are removed from their apertures, they are photographed in situ with both color and black and white film in transmitted and reflected light. These photographs document the colors, intricate lead lines, and the damages to the un-restored panels. This process is also repeated after the studio restoration is complete.

When these windows arrive in the studio, artisans photograph the extracted panels prior to making rubbings with hard wax blocks on rag vellum. These rubbings are marked with specific notations about previous repairs, including any lamination, plating, unstable paint, silver stain, etc. The panels are then dismantled; some are so frail that they fall apart in the artisan’s hands. Next the pieces of tinted and painted glass, sometimes hundreds in a single panel, must be cleaned. Removing crusty residual weatherproofing sealant from the glass usually requires that the craftsmen assemble the pieces on large, shallow cookie trays and deluge them with methylene chloride.

Rebuilding panels

The artisans are meticulous. They hand wash and carefully inspect each piece on a light table looking for damages or loss of detail. Glass that has shattered and cannot be repaired is expertly replaced with newly painted and re-fired glass, with painstaking attention to assure an exact match. Following the pattern of a second working rubbing, artisans cut and bend new lead came in which to seat the glass. With the glass in place, they solder the joints. This process is repeated as they follow the third and fourth layers of rubbing patterns until the window is finished. To seal the glass and lead came, they smooth in a waterproofing compound, tinted gray to match the lead. This multi-phased project spanned a number of years and resulted in about 3,000 sq. ft. of stained glass restoration and a commendation from the Army Corps of Engineers.
