*Survey on the Application of Polysaccharide Gums in the Conservation Treatment of Photographs*
West Lake Conservators in Skaneateles, NY will be conducting an experimental research into the application of polysaccharide gums for the cleaning of supports of photographic crayon enlargements. Crayon enlargements often present severe overall discoloration of the support or staining. Frequently the support is brittle and the applied media is water sensitive, ruling out aqueous washing as an option for treatment. Our research will focus specifically on crayon enlargements mounted on canvas. Conservators have in the last few years successfully used a technique of controlled introduction of moisture using rigid polysaccharide gums. The gum layer also absorbs deterioration byproducts, allowing for a very gentle form of cleaning. The use of this method as it applies to photographic materials has been gaining momentum but is fairly under-researched. We are reaching out to colleagues to undertake a very short survey on their experience with polysaccharide gums in treating photographic materials. We appreciate your time is valuable and are most grateful for your contribution to the project.
