The Typological Passion window is a broken arch lancets from the beginning of the 13th century (1205 - 1215). Several restorations took place since the creation of these stained glass window. The most important restoration was in 1876 by Lorin.
Previous treatment: In 1988, practical tests with the Viacryl®-Desmodur as consolidant were carried out in LRMH. The treatment of the grisaille on internal side of the panel, recommended by LRMH, was two applications (5% of Viacryl®-Desmodur in ethyl acetate) with a paint brush on weathered glass paint only. The overflowing of an excess of consolidant could be taken off with cotton soaked with ethyl acetate, after the beginning of polymerisation (1,5h). Silicone was applied on the edge of broken glasses, after cleaning. It was also used to stick local protective glasses. Bay 37 was restored in 1988 by Alliou studio (Consolidant and Silicone).
More information about the window is available in the Object-Data by Constglass FhG ISC (bay 37 panel 16, bay 37 panel 44). A short description about scientific investigations can be reached directly: panel 16 and panel 44.
