Evaluation of Funori as adhesive for stone polychromy. The XV century Ramon Llull’s sepulchre as Case Study
Main Article Content
Abstract
Adhesion and consolidation of pictorial layers has become one of the main challenges in conservation issues and, despite a growing availability of new resins and polymers, natural, traditional and well-known materials have been studied and improved, in order to face and solve modern issues. During the last conservation intervention on Ramon Llull’s sepulchre, the original polychromy has been rediscovered. A funori solution has been evaluated as the most suitable to undertake the intervention, and a specific methodology was developed in order to fix the layers. Funori’s reversibility and slight surfactant characteristics, allows that the removal of the grey overpaints could be easily carried out with wat
