Abstract
Summary
The effect of heat treatment on changing the color of light-irradiated wood was investigated. The change
in the lightness, ∆L*, of light-irradiated wood with heat treatment was much greater than that of unirradiated
wood. The chroma coordinates, ∆a*, of irradiated wood increased with treatment temperature and
time. ∆b* decreased after showing a sharp increase with a short period of heat treatment. It is thought
that the changes are related to a change in the chemical composition which was accelerated by heat. With
low temperature treatment, the color of irradiated wood changed remarkably with high relative humidity.
Little change in color was observed with low relative humidity. Therefore, heat and the presence of
water accelerated the change in the color of irradiated wood. This treatment is available as a new coloring
method.
