This PhD project will develop a series of damage functions for canvas oil paintings that include chemical processes. These damage functions allow more evidence-based decision making for acceptable museum climates to preserve paintings for future generations. The damage functions will be based on a combination of spectroscopy/microscopy studies of oil paint materials and computational models that combine molecular transport and reactivity. New applications of time- and spatially resolved ATR-FTIR spectroscopy will be developed to study the kinetics of chemical processes inside oil paint films. A versatile computational transport model will be used to calculate how water/solvent concentrations vary throughout the painting stratigraphy when external conditions change.
