An Evaluation of Supercritical Drying and PEG/Freeze Drying of Waterlogged Archaeological Wood

Download: 2007-04
Size: 9.1 MB

This study was undertaken to evaluate the physical effects of drying waterlogged archaeological wood using supercritical carbon dioxide as compared to air drying and the popular polyethlene gylcol (PEG)/freeze drying method. Previous studies have shown supercritical drying to be a potentially advantageous alternative to current methods of drying waterlogged wood through reduced processing time, minimal shrinkage, and increased success for reversibility.
