木材品种繁多,质地不一,颜色花纹相差很多。即使同一树种,它的心材和边材的颜色也不一样。有些木材,颜色纹理优美;有些木材,不但纹理不美,颜色灰暗,而且深浅不均,并有色斑,腻子和浅色油漆无法掩盖其面目。木装饰件用双氧水或次氯酸钠水溶液漂白后,可除去木材原有颜色,不再看到色斑。这样就如同在一张白纸上作画,可以随心所欲地染色。能够把普通外观较差的树种漆成名贵树种的纹理和颜色,如漆成紫檀木、水曲柳等。 There are many varieties of wood, different textures, and many different color patterns. Even in the same species, the heartwood and sapwood are not the same color. Some woods have beautifully-colored textures; some woods are not only unsmooth in texture, but are dark in color, have uneven shades, and have spots. PuTTY and light-colored paints cannot hide their appearance. After the wood trim has been bleached with hydrogen peroxide or sodium hypochlorite aqueous solution, the original color of the wood can be removed and the stain can no longer be seen. This is like painting on a piece of white paper. It can be dyed as you like. It is possible to paint trees with poor general appearance into the textures and colors of valuable trees such as rosewood and Ash.
