For the first time, wall paintings from the Late Middle Ages in a castle in Burgundy and a church in Switzerland have undergone absolute dating, by measuring the carbon-14 contained in a pigment widely used in the paint, namely lead white.
The result, obtained at the Carbon-14 Measurement Laboratory (CEA/CNRS/IRD/IRSN/Ministry of Culture) located at the CEA Paris-Saclay Center in collaboration with the University of Fribourg and the Château de Germolles, paves the way for the absolute dating of works painted from the Antiquity to the 19th century. It is published in the journal Scientific Reports on 12 June 2020.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
