Abstract

Artiklen giver en kort introduktion til nedbrydning af vanddrukkent træ, metoder til konservering og hvordan vakuumfrysetørring kan reducere risici i forbindelse med konservering af nedbrudt vanddrukkent træ. En afgørende parameter for et vellykket vakuumfrysetørringsresultat er valget af korrekt imprægneringsmiddel til imprægnering af træet før vakuumfrysetørring. Næsten tredive års forskning på Nationalmuseet peger på polyethylenglykol (PEG) 2000 som det imprægneringsmiddel, der opfylder de fleste af de anførte kriterier, der er centrale i bevaring af arkæologiske vanddrukne genstande, der indlemmes i museernes samlinger. Træ fra to arkæologiske fundsteder (Nydam Mose og Roskilde Havn), med meget forskellige genstandstyper og nedbrydning, bruges som eksempler på konserveringstilgange og -resultater.
