The Discovery and Comparison of the Manufacturing Secrets of Enamelled Masterpieces

Résumé

The miniaturization and development of the laser sources, optical systems and computer performance in general use for analytical experiments have profoundly changed scientific instrumentation over the past decade. It is now possible to analyze the objects on-site (exhibition areas or storerooms, open-air exhibition, etc.), which revolutionizes the analytical approach and the non-invasive analysis of objects. Two mobile non-invasive analytical techniques that are particularly suited to the study of coloured glassy materials are now available, namely X-ray fluorescence spectrometry and Raman microspectroscopy. In both cases, the electromagnetic radiation (X-ray or visible to near infrared) interacts with the electronic layers of atoms, comprising deep layers for Xrays while it interacts with the surface layers in the case of visible to NIR radiation, and part of this energy of illumination is re-emitted after interaction with the material under study, giving a physicochemical fingerprint of the area illuminated by the instrument.
