Description
The proposed project aims to develop a 3D physical model of paintings with craquelure patterns and through this decisively contribute to the development of evidence-based environmental specifications in museums. Collaborative efforts between partners from Poland and Norway, supported by research groups and museums in France, the UK and the USA will advance knowledge in this cross-sectoral area, blending natural and engineering sciences with conservation and art history. In the first phase of the project, a database of material properties for historical materials used in paintings as well as more modern natural and synthetic materials used in conservation practice for consolidation will be compiled. In particular, fracture toughness will be determined for painting materials containing animal glues such as sizing, grounds and paint layers. Additional investigations of material properties that will inform the 3D model include a quantum chemical study of the molecular level interactions between the organic oil medium and metal ions contained in common pigments to gain insight into the long-term mechanical properties of oil paint layers. As it is the ambition of the project to significantly advance sustainable care and conservation practice for paintings, the global dissemination of the project outcomes to users and stakeholders in the conservation and museum sector is an important task. The international network of institutions involved in the project will aid this effort. Most notably, the project outcomes will support clear recommendations for standardized practices to facilitate institutional adoption. This work will also expand the applicability of HERIe, a web-based decision-supporting tool for assessing risk of physical damage to works of art co-developed by the Applicant. HERIe is uniquely positioned to impact the adoption of sustainable practices since it is offered freely to the cultural heritage community and requires no specialized training
