The effects of oil and air heat treatment on the physical and mechanical properties of Paulownia tomentosa and Pinus koraiensis woods were determined and compared. Heat treatments were conducted at 180, 200, and 220 °C for 1, 2, and 3 hours. Changes in properties of heat-treated woods including color, weight, density, volume shrinkage, abrasion, compressive strength, and hardness were investigated. The oil heat-treated specimens showed a darker color than the air heat-treated specimens. In oil heat treatment, the weight and density increased significantly, but in air heat treatment, the weight and density decreased slightly. The volume shrinkage by oil heat treatment exhibited lower compared to that by air heat treatment. The oil heat-treated samples showed lower weight loss in abrasion than air heat-treated samples. Compressive strength increased by oil heat treatment at all temperatures, in contrast, the compression strength of the air heat-treated samples increased at 180 and 200 °C and rapidly decreased at 220 °C. The hardness of oil heat-treated Pinus koraiensis wood increased, but vice versa in Paulownia tomentosa wood. In air heat treatment, both wood species showed a decrease in hardness.
