< Techniques TECHNIQUES OPTICAL, METALLOGRAPHIC & ELECTRONIC (SEM) MICROSCOPY The use of different microscopy techniques, combined with an elemental microanalysis of energy dispersion X-ray (EDX) to determine the nature of the mineral and metal materials. In the context of authentication, this approach provides information on the nature of the superficial deposits or corrosion products and the degree of weathering of the material, which allows to decide on the chronological compatibility of an object.
