Conservation of stained glass windows

For this protection to be effective, an in-depth climatic study is first required. The parameters to be defined include the distance between the window and the protective glazing, and the nature of the ventilation in the space between the two.

Installation of the stained glass today often occurs with either a vented system in the stained glass or in the protective glazing to be determined before glazing. The stained glass is installed with a Silicone sealant which allows for expansion and contraction or if specified, an isothermal installation.

It should be noted that an individual approach to each and every type of stained glass needs to be analyzed for a successful conservation project. The approach and specifications which we adhere to are as follows: A. Surveys, documentation and in situ photography B. Check for paint stabilization before bathing each section to soften old putties and lead F. View Additional Examples.

Grand Central Terminal largest clockface by Tiffany. Our Conservation approach for restoration is based philosophically on accepted and established preservation theory. The windows being considered for conservation will be treated as an artistic element that is also an integral and functional part of the building fabric, not as museum artifacts. The process begins with a structural inspection of the stained glass windows. One of our studio representatives meets with a church representative to explain the procedure and to gain access to all the windows.

He or she then makes a careful visual inspection of each window, evaluating the individual components of the structural support system. In checking the window, the studio representative assesses if the window is as intended by the designing artist.

A major aesthetic component for many stained-glass windows is the painting that has been done on the interior surface of the glass to develop the design and control the intensity of light.

Unfortunately, the firing is not always exact and some painted areas sometimes are not permanently adhered to the glass surface. Another change in appearance can occur when the glass has been replaced in the past because of breakage. If the original damaged glass was a painted piece, the replacement glass may not be of the same quality as the original, creating an obvious mismatched appearance.

In the inspection, the studio representative makes note of obvious replacement glass, both painted and unpainted. The windows are documented photographically to aid the studio representative and our conservation team in developing a comprehensive Condition Report. The Condition Report and a detailed proposal for the care of the windows are then submitted to the church and discussed with the appropriate church body.

Our trained conservation specialists treat the windows that fall into this category exclusively as the priceless treasure that they are through critical analysis, careful handling, increased safety measure and precise attention to detail both in the art, its documentation and care. By utilizing Conservation techniques, we will retain the artistic component of the window s , maintain the original glass whenever possible, with an emphasis on reversible techniques.
