Influence of pre-treatment on shrinkage of freeze-dried archaeological oak-wood
Abstract The article presents results of the research on the shrinkage of slightly degraded, freeze-dried archaeological oak-wood (Quercus sp.). Before drying, samples of wood were treated with 10, 20, and 30% water solutions of PEG 300, PEG 4000, and sucrose, as well as the mixture of both polyglycols. Dimensional changes in tangential, radial, and longitudinal directions were determined immediately after freeze-drying, and then, after seasoning of the freeze-dried samples in the air at RH 44 and 70%. Shrinkage of untreated and treated freeze-dried oak-wood was considerably smaller, than that of the material, which was dried naturally (ASET from 49 to 97%, ASER from 39 to 98%).
Keywords: archaeological wood, shrinkage, impregnation, freeze-drying
