The article explores the composition and characteristics of Germanic grisailles in stained glass from the 14th to 19th centuries. Through a detailed analysis of panels from different regions and time periods, the study reveals a shift in materials used, with copper-rich pigments dominating in the 18th century. The research addresses the lack of studies on the characterization of Germanic grisailles and provides valuable insights into the technology and production of these glass paints.
By utilising techniques such as micro-particle-induced X-ray emission analysis, the study differentiates between glass types and colourants used in the grisailles based on elemental presence and absence. The results highlight the complexity of the compositions and the need for further research to fully understand the technology of production. The article also discusses the challenges in attributing panels to specific periods due to mixed-alkali compositions and variations in colourant oxides.
Overall, the study contributes to a better chronological and geographic overview of Germanic grisaille paint materials, laying a solid foundation for future research and comparison in this field. The findings offer valuable insights for conservation efforts and historical research related to stained glass compositions and techniques. The article emphasises the importance of continued research in this area to enhance our understanding of the historical significance and technological advancements in the production of stained glass artworks.
