Comparative study between four consolidation systems suitable for archaeological bone artefacts

This study started with the restoration of a 14th century Italian crosier during the final Master year project at the InstituteNational du Patrimone in Paris (Palazzo 2014). The characterization and consolidation of the bone materials constituting thecrosier was needed due to its poor state of conservation.Several products, both organic polymers and inorganic consolidants applied on artificially altered bone material underwentscientific investigations consisting of several analyses and mechanical tests in order to choose the most suitable for therestoration intervention.The results thus obtained showed that both nanolime and a mix of Paraloid® and calcium phosphate seem to be adequatefor treating such objects.
