Possibilities and limits of (non-destructive) analysis of reverse paintings on glass
As part of the SNSF research project on the travel and recipe book of Ulrich Daniel Metzger (*1671), reverse glass paintings by the artist and by his close friend and master Gerhard Janssen are being examined. The investigation has two aims: firstly, a technical and material characterisation of the artworks and secondly, a comparison of the results with the recipes and painting instructions noted in the book. The analysis of materials and techniques, however, is associated with difficulties that are based on the technical specificity of the works, namely so- called ‘églomisé’. The paintings are backed with leaf metals and sometimes also protected by an additional cover of paper, which cannot always be easily removed. There is therefore no direct access to the painting layers.
In this workshop, we would like to discuss the limits and possibilities of (non-destructive) analysis of reverse glass paintings and stained glass. Short presentations will give insights into the analytical practice of various research groups active in the field and provide the opportunity to discuss specific issues of analytical techniques and procedures.
