Conservation materials and strategies for stained glass windows: Microtomography results from the CONSTGLASS project

摘要

The European research project "Conservation Materials for Stained Glass Windows - Assessment of Treatments, Studies on Reversibility, and Performance of Innovative Restoration Strategies and Products" (CONSTGLASS) involved a consortium of 11 partner organisations from 7 countries for a period of three years, beginning in June 2007. This paper provides an overview of results of the project based on the use of synchrotron radiation microtomography. The research activities of the project dealt mainly with the evaluation of conservation treatments performed in the last fifty years on European stained glass windows originating from the mediaeval to the 20th century periods, and taking into account the present state of preservation and/or the potential risks posed by former conservation protocols.
