Reasons for whitening rosewood furniture

For the expensive hardwood, there is a saying of "one black, two yellow and three red" on the market, and one black refers to the rosewood. In fact, the so-called "one black" refers to the rosewood heartwood, the material is red and purple, and for a long time it turns black and purple. In order to summarize it from the color, it is different from other hardwoods. But do you know? The red sandalwood is also white, to be exact, the rosewood furniture is white.

The so-called "white" is similar to "one black". It is not pure white, but gray.

The rosewood turned white, and this has long been said in the folks. In the Panjiayuan antique market, collectors circulated a story of “red sandal whitening and blackening”: in the 1980s, the boss of “Tianmuyuan” went to the countryside to collect rosewood furniture. At that time, rosewood furniture sold more money. The amount of storage in the countryside is not small. Hadron only collects red sandalwood, huanghuali, etc., does not accept wood.

In a village on the bank of the canal, many villagers took out their wooden pieces and the sons were busy "identifying." An old lady came from afar, holding a white pen holder in her hand. Hadron sees white, thinks it is firewood, and shouts from the distance: "Old lady, don't take it, don't want white." The old lady will not go back. After a while, Hadron went to the village again. The old lady trembled and took out a black pen holder. When the hadron looked at the rosewood, she received it. The old lady did not understand: Why didn't you do it last time? The hadron said that it was not white, the old lady said it was this one. It turned out that this pen holder, the old lady has been used to hold salt, for a long time, the pen holder turned white. The old lady later had a more eye-opener. It couldn’t be sold. Is it dirty? Wash it! The old lady washed the pen holder and didn’t expect the pen holder to slowly darken. The old lady thought: White, don't, it just turned black, this time definitely.

If you listen to this story, you still don't believe that the rosewood will turn white. You can go to the Forbidden City to have a look. There are a lot of rosewood furniture turned white. According to Mr. Zhou Jingnan of the Palace Department of the Forbidden City, the reason for the whitening of these rosewood furniture may be the result of long-term sun exposure, because the whitish places are all leaning against the window. Looking at the cow's hair from a whitish place is clearer than the purple-black place.

People who collect antique woodware often use purple sandalwood wine to watch the purple mist, and use it as a magic weapon to identify true and false. This is because the rosewood contains a kind of red sandalwood. This rosewood is found in many dark purple-colored legumes. Although it is contained in hardwood heartwood, it is easily lost. Now there is a process specially prepared for dye extraction. According to Mr. Yang Jiaxuan, the first drafter of the "Redwood" national standard, it is possible that the red sandalwood encounters a substance similar to salt, which causes the loss of red pigment and whitens.
