Abstract
A testing program was designed to check the performance of protective coatings for stained glass conservation. According to test-tailoring principles a well harmonized concept was established including: - suitable test glass spcimens with tailored sensitivity and reproducible surface qualities, modelled to meet the analytical requirements - a cyclic waethering test programm with adjusted aggressivity as well as additional pollution tests with defined immission levels - analytical assesment techniques to detect even smallest submicroscopical surface alternations with proven relevance for future deteroration mechanisms. The test procedure was applied to ORMOCER multilayer protective coatings as well as test coatings with reduced protective features to evaluate failure mechanisms concerning possible long-term effects. The analytical result prove the basic suitability of the new conservation material and indicate the stress input of individual pollutants like SO2, NOX, O3.
