Another application of materials characterization techniques that is less mentioned, however, is their use in identifying the identity and history of a material. This review seeks to explore this application of characterization methods, describing both how the methods are used, and the results obtained, with special focus on optical microscopy, used to examine the surfaces of structures, and various spectroscopies, used in examining various properties such as composition, crystal structure, etc.CC BY-NC 4.0Material CharacterizationOptical MicroscopyX-ray FluorescenceDESI-HRMSArticle
