In this study, samples of wood from black locust (Robinia pseudoacacia Lipsky), wild pear (Pyrus communis L.), linden (Tilia platyphyllos), alder (Alnus glutinosa L. Gaertn.) and willow (Salix alba) were treated at 212°C for 1 hour and 2 hours according to the ThermoWood heat treatment procedure at the Novawood Factory in Gerede, Bolu (Turkey). Colour and glossiness were tested and compared with untreated samples. The results showed that overall, lightness decreased, while the behaviour of a* and b* values depended on the species and on the initial colour. Differences in lightness and a* between species were equalized by heat treatment. Gloss at 20° and 60° angles decreased with heat treatment for both perpendicular and parallel directions, while at 85° an equilibrium was reached between the decrease in gloss due to the heat treatment and the increase due to the lower roughness of the heat-treated surface.
