Abstract

The aim of this project is to study a group of corroded Egyptian gold objects held in collec- tions of the National Museums of Scotland, the Louvre Museum, and the Garstang Museum of Archaeology. The corroded surfaces with several areas of different colours were examined and the corrosion products identified using SEM-EDS and μXRF. It was suggested that the corroded surfaces are composed of Au-Ag-S-based compounds developed in a layer-by-layer structure. Elemental data associated to surface morphology suggested that the different surface colours are related not only to the thickness of the corroded layers, but also to the morphology of the corrosion products.
