CURRENT RESEARCH ON THE EFFECTS OF SOLVENTS AND GELLED AND AQUEOUS CLEANING SYSTEMS ON OIL PAINT FILMSJIA-SUN TSANG, & DAVID ERHARDT
ABSTRACT—Some current research, in the authors' laboratories and elsewhere, on the effects of solvent and aqueous-based cleaning systems is reviewed. The application of varnish is considered in terms of the exposure of the paint film to the solvents used to dissolve and apply the varnish. The varnish and solvent solution is seen as able to act as a poultice in leaching soluble components from the paint film. The action and effects of some aqueous and gelled systems also are considered. Initial data indicate that soaps and gels behave in some ways much as solvents do, both in the time frame of their action and the amounts of materials that they can remove from paint films to which they are applied.
