Vibrational spectroscopy at the service of industrial archaeology: Nineteenth-century wallpaper

摘要

We present an overview of the application of some vibrational spectroscopic techniques (Fourier transform infrared (FTIR) and Raman) to industrial archaeology in the field of cultural heritage, particularly centered on the wallpaper industry. Both techniques present a better performance for cost than other set-ups applied to the analysis of multilayer artworks on cellulose supports. To illustrate the applicability of these techniques, we present examples of different decorative wallpapers from the whole nineteenth century and compare the results obtained with other artworks from the same century.
