Abstract

The study compared the ability of seven bleaching agents to remove the blue colour from blue-stained lodgepole pine without adversely affecting the colour of unstained heartwood. A 10% solution of sodium hypochlorite was effective at removing the blue colour from blue-stained lodgepole pine sapwood. Sodium hypochlorite did not adversely affect the colour of heartwood, whereas three other bleaches initially caused a pronounced yellowing of heartwood, which faded over time.
