Documentation of glue pasta recipes for lining in Europe

The objective of the project I+D+I “Materials and methods of pasta linings for the reinforcement of canvas paintings: documentation, functionality and conservation” (HAR2011-24217), funded by the Ministry of Economy and Competitiveness of Spain, is the study of traditional lining with glue paste from documentary sources (collection of recipes, materials and methods used), and through an experimental phase (accelerated aging tests, biodegradation and mechanical behaviour on lining samples). In this case we have focused on the information obtained in treatises, archives, reports, invoices and applications for registration of trademarks and patents of some materials, consulted in various museums and institutions. This information has been enlarged and compared to the analyses performed on lining adhesives used in some case studies selected for the project in these institutions because of their characteristics
