Some protective resin coatings may damage metal artifacts
Conservators and museum technicians protect precious archaeological metal objects, such as tools and weapons, with clear coatings, leaving preserved and unobstructed views of these detailed treasures. However, researchers have reported that some of the resins used for these coatings react with iron-containing metals and can cause damage. The team developed a non-invasive fluorescence imaging strategy that reveals early signs of these damaging chemical reactions and confirmed its utility on ancient artifacts.
