Description

Wood degrades during the storage in the ground. Depending on its state of preservation and species, archaeological wood will deform, collapse and shrink after excavation. This paper reviews conservation methods used to preserve waterlogged archaeological wood. In the short history of conservation science, various methods have been established. At the Leibniz-Zenturm für Archäologie, a reference collection has been built up considering conservation methods such as alcohol-ether resin, melamine formaldehyde (Kauramin 800®), lactitol/trehalose, polyethylene glycol impregnation with different molecular size followed by freeze-drying, saccharose and silicone oil. The project “Cutaway – Conservation and wood analyses” aimed to compare the treaments and therefore, samples of the reference collection were analysed using structured-light 3D sanning, X-ray and synchrotron micro-computed tomography, light microscopy and scanning electron microscopy. The paper discusses the ability of these methods to prevent shrinkage, collapse and cracking. In addition, the interaction of the consolidant within the microstructure of the wood and the condition of the cell walls is assessed.
