Spectroscopic techniques in cultural heritage conservation: a survey

This review describes the application of selected spectroscopic techniques to the world of cultural heritage conservation. In recent times, science and technology have been applied to the world of cultural heritage, conservation and preservation. In this field, spectroscopic techniques represent one of the most powerful tools to investigate the structure of all the materials constituting the "cultural object." In particular, this survey will consider the "status of art" in the field of some important spectroscopic techniques for the characterization of the following works of art: easel paintings, paper and ink artifacts, stone monuments and wall paintings, and archaeological ceramics. The spectroscopic techniques that have been used and will be reviewed are Fourier transform infrared spectroscopy and also coupled with the microscope, X-ray fluorescence spectroscopy, proton-induced X-ray emission spectroscopy, ultraviolet, visible and fluorescence spectroscopy, Raman spectroscopy, and Mossbauer spectroscopy.
