Abstract

This study investigates innovative non-toxic carboxylate protection treatments against corrosion of statuary bronze artefacts. Over the past decades, research has focused on conserving these objects exposed to the atmosphere with special attention on the preservation of corrosion layers (CL). Recent studies have reported the efficiency of long chain carboxylates in protecting copper patina from subsequent deterioration.
