Effective and responsible use of solvents is an important competence of a conservator/restorer. The goal to selectively remove components such as varnishes from the surface without affecting underlying paint is a common challenge in the field of restoration. The complexity of the processes of solvation and dissolution has given rise to several approaches by various groups to simplify solvent action and deliver some selection criteria to the restorer. In general, however, these approaches lack both a qualitative and quantitative description of the dissolution processes. In the context of practical conservation needs, knowledge of the rate of solvent action will decide the ability to control a conservation treatment. Since the kinetics of solvent action mainly depend on an entropy change in the dissolving process, a different approach is necessary to satisfy the demands of current conservation practice.
