Effect of Sunlight on the Change in Color of Unsteamed and Steamed Beech Wood with Water Steam.

This paper presents the differences in the color changes of unsteamed and steamed beech wood ( L.) caused by long-term exposure to sunlight on the surface of wood in interiors for 36 months. The light white-gray color of the yellow tinge of native beech wood darkened under the influence of sunlight, and the wood took on a pale brown color of yellow tinge.

Influence of UV Radiation on the Color Change of the Surface of Steamed Maple Wood with Saturated Water Steam.

The wood of maple ( L.) was steamed with a saturated steam-air mixture at a temperature of = 95 °C or saturated steam at = 115 °C and = 135 °C, in order to give a pale pink-brown, pale brown, and brown-red color. Subsequently, samples of unsteamed and steamed maple wood were irradiated with a UV lamp in a Xenotest Q-SUN Xe-3-H after drying, in order to test the color stability of steamed maple wood.
