Abstract
Vietnam has a long history with great amount of waterlogged wood found at archaeological sites. The conservation of those woods became important task since it referred to “cultural properties”. These wooden artifacts were deteriorated after centuries under the ground and need to be well preserved for keeping its original shape to be exhibited in museum and/or long-term storage. However, the conservation techniques applied for those timbers are not the same, depending on classifying wood as either a hardwood or softwood, species, degradation levels and so on. A new treatment method was developed for archaeological waterlogged wood using avian feather (Endo et al., 2008, 2010) and feather-keratin powder (Endo et al., 2015). In this study, feather-keratin powder was used for conservation of Vietnamese waterlogged woods. The stabilization capability of wood treated with feather keratin solution such as shrinkage in three directions and volumetric shrinkage were also determined. The results showed that the dimensional stabilization of Vietnamese waterlogged wood treated with keratin was really good.
