  ABSTRACT. Advanced physical chemical techniques, such as differential scanning calorimetry, thermogravimetry, IR spectroscopy, scanning electron microscopy and unilateral nuclear magnetic resonance were employed to assess specific deterioration processes occurring at individual levels in the hierarchical structure of parchment. Changes in the structural and physical-chemical parameter values of collagen due to interaction with the environment were used to characterize deterioration pathways.
