Summary
The lack of a suitable method on an industrial scale has so far restricted the use of bleaching of solid wood in the woodworking industry. In this study, a new method ‘Wood-Brite™’, based on bleaching solid wood blocks with hydrogen peroxide solution, was investigated. According to our measurements, the lightness of all the wood species studied could be increased and the increase could be controlled by the intensity of peroxide treatment. Differences were observed in the change of chroma and hue of different wood species. Redness usually decreased regardless of the treatment intensity, except with teak, in which it increased markedly. At every treatment intensity, the yellowness of originally light birch wood decreased, but in other wood species it increased.
