This study measured the effect of heat treatment according to the ThermoWood method on the colour and glossiness properties of selected exotic wood species. For this purpose, Afrormosia (Pericopsis elata), Doussie (Afzelia bipindensis), Frake (Terminalia superba) and Iroko (Chlorophora excelsa) were heat treated at 212°C for 1 hour and 2 hours using the ThermoWood method in Novawood Factory, Gerede, in Bolu, Turkey. After this process, the glossiness and colour of the untreated wood were tested in comparison with the heat-treated samples. The results show that the colour (L*, a* and b*) and glossiness (parallel and perpendicular to the grain at 20°, 60° and 85° angles) were changed by the treatment. Generally the L* and glossiness of the surface decreased and the ΔE* and a* increased with the intensity of the treatment.
