A preliminary infrared study of the cellulose of some world stamps

Abstract The infrared spectrum of seven heavily damaged stamps was measured to analyze the cellulose, fillers and sizing elements composing them. In five of them kaolinite was detected as a filler. In one of them Prussian blue was detected as a component of a greenish-blue paper. An attempt to classify them employing a decision tree led to the conclusion that more data from other experimental analysis (XRF) is needed to achieve this goal.
