Historical colour research

Historic buildings undergo changes in function, form, and appearance over time, often resulting in modifications to the structure and alterations in decorative and color finishes. Our color researchers meticulously study and document this history, mapping the evolution of the building's finishes.

Methodology

In a  historic colour research small areas of successive paint layers are uncovered with a surgical knife, creating a "color stage." Paint cross-sections of samples are also analyzed to map the composition, original appearance, and sometimes the dating of the layers more precisely. Advanced instrumental techniques, such as electron microscopy and infrared spectroscopy, may be used to determine the pigments and binders involved. The results from analytical research and on-site examination of paint layers are compiled into a detailed report. Historical sources and other records of building and cultural history are also consulted to provide a comprehensive picture of the finishing history of building interiors and exteriors.

Interdisciplinary

The interdisciplinary collaboration of a large team of specialized conservators enhances the efficient interpretation of data. With targeted advice and a deep understanding of historical paint finishes, our conservators support and oversee projects involving decorative painters by setting up test surfaces and providing expert guidance.
