Description

Archaeological copper alloy objects exhibit varying levels of corrosion due to prolonged exposure to burial environments. The different corrosion mechanisms and morphologies relate to the varying corrosivity of these burial settings, the diverse corrosive factors present in the burial media, and the metallurgical characteristics of the archaeological objects. The use of various analytical and microscopic techniques has enabled scientists and conservators to identify these corrosion morphologies and mechanisms, as well as establish appropriate conservation treatments to manage the corrosion rate in museum collections. This presentation aims to showcase different aspects of the study and analysis of archaeological copper alloy objects through modern microanalytical techniques and to highlight the importance of applying these techniques in archaeological science and conservation.
