A Chemical and Historical Study of the Glass Paint 'Jean Cousin Red'. J. Albert, K. Peters, J. Caen. In this paper, the authors "… researched existing medieval literature on the subject of Red Jean Cousin, and conducted chemical analysis of two paint powders and of glass fragments containing a layer of red jean cousin from various stained glass windows. This resulted in defining the right conditions needed to obtain a paint with a carnation color." |
Contribution to the Study of Cold Paint on Ancient Stained Glass Windows. C. Fontaine, M. van Bos, H. Wouters. The authors report their findings regarding the occurrence of cold (unfired) paint on ancient glass. In the first part of the paper, they collect evidence on glass and in archival records, compare both, and define the function of cold paint. In the second part, they conduct various types of scientific analysis to identify the paints and determine their chemical composition. |
Practical and Ethical Appraoch for the Treatment of Stained Glass M. Juteau. In this article the author presents the ethical guidelines applicable in the general practice of stained glass windows restoration. Her recommendations focus on the appropriate practical and ethical steps to take when reconstructing areas of missing glass. |
Glass Gap Replacements: Corolation and Durability Studies J. Burck, D. Germain, D. Geronazo In this article the authors examine several aspects of the use of synthetic polymers (epoxy, silicone) as a method of glass reconstruction for very small areas of missing glass. These aspects include: the application process, coloration and durability of the polymers. |
Experiments on Trace Paint Consolidation C. Mueller-Weinitschke "In the glass restoration workshop at the 'Kölner Daumbauhütte', practical experiments with various fixation agents were performed to fix loose paints. Three agents, Paraloïd B72, Ormocer, SZA, were compared with regard to their practical handling and optical effects. In addition, the agent most commonly used at the present time, Paraloïd B72, was tested in various concentrations and various solvents. In order to render the experiments as realistic as possible, they were undertaken on modern, antique glass with artifivially damaged painting. The simulation procedure proved very well adapted to the testing of adhesive materials used on paint layers under reproducible conditions." |
Conservation of Original Pieces, Illusionist or Non-Illusiionist Reintegration of Missing Glass A. Pinto "Based on two very different examples, this paper introduces the considered course of actions for the restitution of large areas of missing glass without the reference of existing archives. It explains the reasons for the decisions made, and examines the thought process in dealing with glass replacement in general. The two examples include the fragments of a late 14th century stained glass panel, the Magi King Balthazar, as part of the collection of the Musee de l'Oeuvre Notre-Dame in Strasbourg, France; and the fragments of a 19th century stained glass, a Baptism of Christ scene, still in its original setting in the village chapel of Ansac en Charente, France." |
