Summary:A method of impregnating wood with liquid puts the wood in a pressure vessel, immerses the wood in the liquid contained in the pressure vessel, pressurizes the liquid to compress the wood while keeping the temperature of the wood at or above the softening point of the wood, and reduces pressure in the pressure vessel so that the wood may cause volume relaxation in the liquid and be impregnated with the liquid.
