Abstract

Hydrothermal treatment of wood, especially steaming, is often used to achieve a more intensive and homogenous color of wood or to change its hue. Color hornogenisation of cherry wood (Cerasus avium L.) and Black Locust (Robinia pseudoaccacia L.) was investigated. We obtained this with steaming in steaming chambers. Temperatures of 95°C and 110°C were used. The samples were removed from chamber in time period (1, 2, 4, 7 and10 days). The results were evaluated with color co-ordinate system CIE L*,a*,b*. With rising temperature the color homogenization was faster and less time was needed. Values of lightness L* of cherry wood became stabilized in the same time (the 5.th day) regardless of steaming temperature. Wood steamed at higher temperature had less red hue in the end of steaming process. Values of yellow hue were not changed a lot. The lightness L* of black locust decreased during steaming. Red hue was changed greatly in the first days and the decrease of yellow hue was very variable. The decrease of this value was regular and stronger in the first days. It can be due to faster color homogenization when using higher temperature. The results could have a practical value in the application of color measurement during hydrothermal procedures aimed at the obtaining of desired color.
