Colour and substrata affected choice of binding agents

Inga-Lill Nyström from the Department of Conservation heads an interdisciplinary research project on the interiors of Hälsingland farmhouses. The farmhouses, whose interiors were painted during the 18th and 19th centuries, are part of a UNESCO World Heritage Site, and the studies relate to their decorative paintings, among other things. A new study within the project now shows that colour and the substrata that was painted were decisive in the artists’ choice of binding agents. The study is a collaboration among researchers at Stockholm University’s Archaeological Research Laboratory and the Department of Conservation.
