Il degrado di manufatti ceramici archeologici: sistemi diagnostici e metodologie di intervento

ALTERNATIVE MATERIALS FOR PROTECTING CU- AND AG-BASED ARCHAEOLOGICAL ARTEFACTS

A novel scientific approach to the conservation of archaeological copper alloys artefacts

A novel research approach focused on innovative materials and methods to assure the long-term stability of bronze archaeological artefacts during exhibition and storage is reported. The work deals with the application of advanced analytical techniques and the development, characterisation and testing of materials and procedures for the conservation, protection and restoration of ancient Cu-based alloy artefacts. Our first aim was the selection of Cu-based alloy artefacts from different archaeological sites in Southern Italy with respect of chemical composition, metallurgical features and corrosion products. This step allowed the identification of the ancient alloys, the study of natural pat…
