Abstract

Magnetic Resonance Relaxation (MRR) and Magnetic ResonanceImaging (MRI) are powerful tools to obtain detailed information on the pore spacestructure that one is unlikely to obtain in other ways. These techniques areparticularly suitable for Cultural Heritage materials, because they use water 1Hnuclei as a probe. Interaction with water is one of the main causes of deterioration ofmaterials. Porous structure in wood, for example, favours the penetration of water,which can carry polluting substances and promote mould growth. A particular case iswaterlogged wood from underwater discoveries and moist sites; in fact, these findsare very fragile because of chemical, physical and biological decay from the longcontact with the water. When wood artefacts are brought to the surface and directlydried in air, there is the collapse of the cellular structures, and wood loses its originalform and dimensions and cannot be used for study and museum exhibits. In thiswork we have undertaken the study of some wood finds coming from Ercolano’sharbour by MRR and MRI under different conditions, and we have obtained acharacterization of pore space in wood and images of the spatial distribution of theconfined water in the wood.
