Even after drying, oil paintings are subject to slow chemical and physical processes that can alter their appearance and structural integrity. A common issue in oil-paint conservation is the formation of metal soaps, which are complexes of metal ions with long-chain fatty acids, which have been linked to many types of paint deterioration. The aim of Joen Hermans's research is to improve our understanding of the structure of metal soaps and the polymerised oil network in various stages of oil paint ageing.
