Abstract:
A method for method for producing a fancy log with a decorative and complicated external appearance from a primary wood in the shape of a log, without utilizing a mold, wherein said primary wood is compressed to a desired compression ratio of about 50% by cross-sectional ratio and said primary wood is selected from the group consisting of cedar, larch, Japanese cypress, Port Orford cedar, Douglas fir, Oregon pine, and Western hemlock, said method comprisinga) softening said primary wood, in the shape of a log, having a water content between 10 and 80% by weight by heating said primary wood to a temperature above a softening temperature of said primary wood of about 100.degree. C. to form a softened primary wood, andb) compressing said softened primary wood, in the shape of a log, using hydrostatic pressure in the range of about 12 kgf/cm.sup.2 G to about 30 kgf/cm.sup.2 G to form said decorative and complicated external apperance and a compressed primary wood having a compressed state with a higher density and hardness than said primary wood, wherein the hydrostatic pressure is produced from a pressurized liquid having a temperature of about 100.degree. C.
