Abstract
In this study, the development of non-homogeneous color changes in oak timber
during conventional drying and their relationship with the moisture gradient
across the wood thickness were analyzed. The research was conducted on
radial and tangential boards with a thickness of 38 mm, cut from two oak
logs, one of sessile oak (Quercus petraea L.) and one of pedunculate oak
(Quercus robur L.). A conventional drying schedule commonly used in
enterprises was applied, and at specified time intervals samples were taken
to determine the moisture content profile and monitor color changes on the
cross sections of the samples. The findings reveal a complex relationship
between the wood moisture content, the moisture content profile across the
thickness, and the occurrence of color changes. Additionally, it was found
that the wood of sessile oak dries slower and with less intense color
changes compared to the wood of pedunculate oak. It was demonstrated that
quarter-sawn boards dry slower compared to flat-sawn boards for both wood
species. No differences in the appearance of non-homogeneous color between
quarter-sawn and flat-sawn boards were identified.
