Implementation of MiCorr and DiscoveryMat applications at the Olympic Museum in Lausanne to diagnose aluminium-based objects

Rayan Ammon, a bachelor student at the Haute Ecole Arc Conservation-restoration, Neuchâtel, has just started his internship at the Olympic Museum in Lausanne for his 3rd year diploma. He will diagnose aluminium-based objects in the collections, in particular those used for torches and sports accessories. After a first selection of a corpus of representative objects, Micorr was used to validate that the materials were indeed aluminium-based. A magnet is a valuable tool to exclude other grey materials such as steel or nickel-plated brass. Measuring the surface conductivity of the metal is also essential to check whether or not a surface treatment (anodising) has been applied. The next step will be to use DiscoveryMat to define the composition of the selected artefacts.
