The results show the presence of kaolinite used as filler in all but two samples. These last two contain aluminum (with an Al-OH moiety). One stamp seems to contain barium in the form of sulfate. One stamp contains lead in an unknown chemical compound. All these results were incorporated into a database for future analysis. Quantum chemical calculations of diverse large models of cellulose seem absolutely necessary for the IR band assignments.
