Abstract:
Leafcasting is not only a fast conservation technique, but also provides superior aesthetic quality and homogeneity between the old paper and the new fill. The influence of polymers such as starch and cellulose ether surface coating on the properties of leafcast paper was researched in the framework of a project entitled Optimization of conservation leaf casting technique. The aim of the research was to optimize the effect of different types of starch and methylcellulose used for leafcasting. Several chemical, physical, mechanical and optical qualities were tested for 15 different coatings in total. The values attained confirm the hypothesis that each type of polymeric adhesive reacts differently during coating. In addition, each type affects the end properties and applicability in conservation differently. Wheat starch and methylcellulose of lower DP were proved to provide quite good results during aging. Other coatings were less stable and thus less appropriate for restoration purposes.
