SHORT COMMUNICATION SOLVENT SENSITIVITY TESTING OF OBJECTS FOR TREATMENT IN A VAPOR-SATURATED ATMOSPHERE
ERIC F. HANSEN, & PAULA VOLENT
ABSTRACT—The authors discuss certain limitations to the technique of consolidating porous paint in a vapor-saturated environment described by Hansen et al. in earlier articles. The treatment of a severely flaking gouache on paper by Karel Appel is described, including various tests carried out using the chosen consolidant, a solution of poly(vinyl acetate) AYAF in ethanol, both in and out of the vapor-saturated environment. The final tests failed to provide the desired effect, resulting in some discoloration and staining of the treated areas. The artist himself later was consulted and indicated that his technique had helped create the problems in the consolidation process. In conclusion, the authors point out that it is extremely important to test the consolidant carefully with increasing exposure to solvent vapor before using it on an actual object.
