ABSTRACT:
A method for treatment of an organic material containing art object, such as a wood carving, a painting on wood or canvas, a textile hanging or a tooled leather saddle, for preservation and restoration thereof. The method includes the steps of partially impregnating the art object with an unsaturated resin and exposing the partially impregnated art object to a large dose of radiation to polymerize the resin, without addition of any catalysts and without the production of any significant exothermic reaction. The polymerized resin strengthens the art object and the radiation sterilizes the art object, destroying insects, molds, and other destructive biological vectors.
