Des savons metalliques pour la protection du patrimoine

摘要

The environment is the main cause of the decay of metallic elements from the cultural heritage.Art curators with the support of analytical science attempt to intervene to stop the deterioration.To avoid further degradation,in generai the apparition of corrosion products,a more or less insulating barrier must be created on the metallic surface between the object and the atmosphere.For this purpose,two laboratories develop several anti-corrosion formulations based on sodium carboxylates which are nowadays used as temporary protection for lead and bronze artefacts.
