| Abstract: | SUMMARIES. The purpose of this study was to evaluate the potential harmfulness of different kinds of erasers (factice, vinyl and styrene-butadiene copolymer based) on paper cellulose by following its degradation during artificial ageing treatments. The method of analysis used was the size exclusion chromatography. CONCLUSION. The results of SEC analysis confirm those obtained by previous studies: in a chemical point of view, vinyl based are the less detrimental erasers for paper cellulose. We showed that among the 3 other erasers tested, Design Artgum seems to be the most harmful; then in decreasing order: Wishab and Poudre Stouls. Because of the complexity and the large variation in composition between the different erasers, it is difficult to generalise the effects of a particular eraser to a whole category (Mars Plastic for vinyl based erasers, Design Artgum for factice erasers, etc.). To confirm these tendencies, more tests should be performed. However, these results must be relativized. The artificial ageing conditions are considered as "extremes" and an observation at a high magnification shows that not much crumbs remain in the pores of the paper after erasing and brushing. So, these tests do not aim at preventing the use of some erasers in paper conservation but they should rather help the conservator in choosing the less harmful eraser for a given document or a given treatment. |
