Abstract
The article gives a short background about degradation of waterlogged wood, methodsfor conservation and how vacuum freeze-drying can meet the challenges related to the conservationof degraded waterlogged wood. A crucial parameter for a successful vacuum freeze-drying result,is the selection of the appropriate impregnation agent for pre-treating the wood prior to vacuumfreeze drying. Almost thirty years of research in the National Museum of Denmark points to Polye-thylene glycol (PEG 2000) as the impregnation agent fulfilling most of the listed criteria that arecentral in conservation of archaeological waterlogged artefacts that will be incorporated in heritagecollections. Wood from two archaeological sites (Nydam and Roskilde Harbour), with very differenttypes of artefacts and degradation, are used as examples on the conservation approaches and re-sults in the National Museum of Denmark.
