Abstract: The paper
presents a comparative analysis upon the colour
of veneers resulted from freshly cut beech wood
(with sap) and from beech wood treated by hot
water immersion at 90°C, respectively. The
colour parameters were measured both for the white
wood and the red heart wood and the colour differences
that occurred after drying at different temperatures
were determined as well.
Key words: beech veneers, drying,
colour.
