Maartje Stols is assistant professor paintings conservation and specialises in the investigation of historical artists’ recipes using reconstructions. Stols’ PhD (2014) focuses on historical recipes for preparatory layers for oil paintings in NW Europe, 1550-1900 (University of Amsterdam). Stols heads the NICAS seed money project ‘Scientific Reasoning in Art: Evaluating Evidence in Paintings Research using a Bayesian Approach’. Her research interests include reconstruction methodology, with particular emphasis on the use of ‘historically informed’ materials and the role and methodologies for reconstructions within different disciplines. Stols is currently investigating historical recipes for alcohols, soaps and lyes that were formerly employed in the cleaning of paintings. Within ARTECHNE, Stols will be involved in reconstructions of paint manufacturing recipes. Together with Dupré, Stols organises a workshop on reconstruction methodology.
