Many people don't understand that mahogany furniture is so expensive, so good, how can it change color after a long time? In fact, this can be understood, because everyone will think that the expensive things are perfect, they are impeccable, but it is not, because perfection does not exist.
This will make you feel better: gold is more expensive than mahogany, but when you wear it for a long time, the color of gold will turn black and the weight will become lighter. In fact, mahogany furniture will change color after a long time, which is normal. Just like people, every little change happens every year, and now you will never look like a decade later.
Gossip less, the book goes back to the book, Xiaobian gives you a popular science, mahogany furniture is permanent, why it will change color.
The wood contains moisture. Even if it is artificially dried, it is impossible to remove 100% of the water from the wood. Moreover, proper moisture can maintain the toughness of the wood.
When the water content in the wood is relatively high, it is exposed to the air for a long time, and the surface of the wood will react with air, such as pigments, alkaloids and sugars in the rosewood, the most important ones being phenols and other organic substances.
The phenolic compound is colorless before oxidation, and some of it is soluble in water. After oxidation, it forms a water-insoluble condensate. The color is red, reddish brown and brown, which is an oxidative discoloration. Some tree materials contain tannins, also known as plant tannins, which are mixtures of polyphenols. When exposed to iron under humid conditions, the tannins react with iron to form a chemical reaction (forming iron tannic acid). The color of the wood is discolored.
The mahogany furniture will change color after a long time. In fact, it is not a bad thing. As Yayun Hongmu said, mahogany furniture is like a person. It will look like a year, accompanied by the owner to see Yunjuan Yunshu, see the flower blossom. The process of discoloration and discoloration is the process of passing the time, and it is also the process of companionship of the mahogany. This kind of wood will also be given the human nature, just like a member of the family, accompanied by generation after generation.
