The research was undertaken on archaeological mature sapwood of Scots pine (Pinus sylvestris L.), characterised by a considerable degree of degradation, but low tangential and radial shrinkage and relatively high longitudinal shrinkage. The waterlogged samples were treated with 30% aqueous solutions of sucrose, lactitol, PEG 300, PEG 4000 and then air-dried or treated with ca. 30% aqueous solution of a mixture of PEG 300 and PEG 4000 and then freeze-dried. Effectiveness of modification was evaluated on the basis of wood shrinkage in the three anatomic directions after impregnation, drying and seasoning of the samples in the air at RH 40% and 65% as well as on the basis of hygroscopicity of treated and seasoned samples. Modification of wood with PEG 300, sucrose, and lactitol caused, that linear shrinkages did not exceed 0.5%. The same results were obtained after freeze-drying of wood that had been treated with the mixture of both polyglycols. The latter variant of modification caused, that the treated material absorbed lower quantities of water.
