In this study, some physical properties of wood heat treated with vegetable oil were examined. In the study, Oriental Beech (Fagus Orientalis L.) wood was used as the testing material and corn oil was used as the vegetable-based oil. In the study, oil heat treatment temperatures and times were carried out at 150 °C and 210 °C for 2.5 hours and 5 hours, respectively. After oil heat treatment, the physical properties of the wood samples, such as oven-dry and air-dry density and water uptake percentages, were detected according to TS ISO 13061-2 2472 standard. According to the data obtained, the oven-dry and airdry densities of the oil heat treated samples increased compared to the control samples. Among the oil heat treated samples, the highest oven-dry density value was determined in the samples heat treated at 150 °C for 2.5 hours. Besides; Among the oil heat treated samples, the highest air dry density value was obtained in the samples heat treated at 210 °C for 2.5 hours. In the study, according to the water uptake test results, oil heat treated samples had lower water uptake compared to control samples. Additionally, after a 120-hour water uptake period; While the lowest water uptake, 49.94%, was determined in the samples subjected to oil heat treatment at 150 °C for 5 hours, the highest water uptake was determined in the control samples, with 80.51%. In summary, the oil heat treatment method with corn oil was effective in reducing water uptake of wood material.
