Spectral database for postage stamps by means of FT-IR spectroscopy

The evolution of the connections between Art and Science has been continually developing over the last few years. Today's science and technology developments have led to many different approaches being used in the study of Cultural Heritage. New non-destructive methodologies allow one to apply physical and chemical analysis methods to valuable objects. As a result of the mid-infrared spectra acquired in ATR mode, changes in paper composition show the transitions from different kinds of materials. Philately is a form of collecting that suffers from the same problems as other kinds of collections, such as conservation, restoration, counterfeiting and even understanding of materials and substances employed during the manufacturing procedure.
