Linas Luko‰eviãius, Janina Luk‰ònienò, Riãardas Maku‰kaConsolidation of a paint layer in Old painting with Glutinous GluesAnimal glues made from cattle hides and bones also from rabbit hides and fishglue made from skins and from swimbladders (isinglass) have been studied inconnection with the use of these natural polymers in restoration of paintings.Viscosity of glue splutions, dependence of viscosity on temperature and onsolutions acidity were investigated. Alterations in the colour of glue films and thechanges in glue acidity during the artificial ageing were determined. Tests ofadhesive properties and hygroscopicity of glues were made. Evaluation andcomparison of the obtained data were made for the assess of usability of naturalglue for adhering and consolidating ground and paint layers.54 / TYRINñ JIMAI
