Metal and corrosion: Implications for industry and cultural heritage
Metal is a living material… With the exception of pure gold in its natural state, all metals are derived from the transformation of mineral ores. Once altered, from ore into semi-finished products such as ingots, billets, blooms or slabs, and then into objects or structural elements, metals will continually seek, throughout their service life, to return to their natural state as mineral ore (hydroxides, oxides, sulphides, carbonates, etc.). A leopard cannot change its spots!


Research and innovation
Archaeologists seek to understand past lives in order to better anticipate our lives in the future. We have chosen to apply this principle to metallic materials: understanding ancient metals allows us to better diagnose, assess and preserve them, as well as to develop innovative materials and techniques to protect them and improve durability.
