1979 edition of Cihai holds that "wood buried in soil for a long time due to stratum changes is called' black wood', also known as' black wood sand'. Generally speaking, it is mostly Chinese fir, which is hard and durable. In the past, it was considered as a precious wood for making coffins. " It's cloudy in the north of the mountain and the south of the water. Generally, people born in Shanbei or autumn and winter are called shady trees. Shaded wood is obviously different from dark wood. Yin wood is born on the ground, and dark wood is buried underground.

Shaded wood is not only a kind of Chinese fir, but also a general term for many kinds of wood that have been buried underground for a long time and can be used as utensils. These Woods are characterized by moisture-proof, insect-proof, anti-corrosion, fragrance and heavy oil. There are many kinds, mainly cypress, Chinese fir, nanmu, Fraxinus mandshurica, wild litchi, bitter catalpa, runnan, iron pear and so on. Dark wood has different names in all parts of the country. It is called "Langmu" and "Shuijiangmu" in the Songhua River Basin in Northeast China, and "Ebony" in Sichuan (the main hidden wood is generally dark in color). There is also an ebony art museum in Chengdu, Sichuan. But in fact, Sichuan does not produce ebony, which is produced in Africa, South Asia and Southeast Asia. The so-called "ebony" in Sichuan is actually a kind of gloomy wood, which is very different in concept and essence and cannot be confused.

Shade wood has medicinal value. In the thirty-fifth volume of Li Shizhen's Compendium of Materia Medica in the Ming Dynasty, it was recorded that "Mume is sweet, salty, flat and detoxifying, and it also governs (cures) cholera diarrhea, taking scraps and grinding them into powder, and taking them with warm wine." In the gloomy wood we collect, a strange smell often comes out at night, especially in the finished product exhibition hall. The faint fragrance lingers for a long time after entering the room and is secreted into the heart and spleen. Because ebony is a mysterious and precious "treasure" and "artifact", there is a folk saying that "even a box of jewelry is not as good as ebony".

Yuan Mei, a great scholar in Qing Dynasty, explained the gloomy wood in Wuziyu as follows: According to legend, gloomy wood is a tree that started the world. When it sinks into the sand waves, it subverts the fate of the world, reappears the world, and makes it buried again, which will not be bad for ten thousand years. Its color is dark green, and its pattern is like brocade. Put a piece on the ground, and a hundred paces away, flies can't fly.

At the beginning of last century, western missionaries came to China and saw this kind of wood in some remote mountainous areas, which was called "Oriental Shenmu". According to the analysis of existing data, in ancient times, the precious ancient trees in a large area of virgin forests have grown for more than a hundred years or even thousands of years, and they are towering. However, due to sudden major geographical and meteorological changes (such as earthquakes, flash floods, lightning strikes, typhoons, etc. ), they are buried deep under the mud and sand of ancient river beds and rivers and lakes, and buried underground for thousands or even tens of thousands of years without oxygen. After years of vicissitudes, it was eroded by wind and rain and washed by rapids.

Shaded wood is a kind of precious wood. Judging from the texture of shady wood, there are many kinds of ancient native wood, such as Phoebe bournei, amethyst, grape, slope barrier, green bar, Liu Ma, coriaria and so on. , especially some ancient precious redwoods, such as ancient nanmu, rosewood and rosewood. Because it has been buried underground for thousands of years, it has different colors when unearthed, some are black as a whole, some are gray and brown like clouds, some are red as granite, some are golden, the outer black and inner yellow are golden nanmu, the outer black and inner red are slopes, and the outer black and inner green are Zhennan and so on. Because it is buried for a long time, it has a high density and is hard and heavy, but it is heavy when it is put in water.

Reference/View/1 10257.htm Daphne has been a very precious wood since ancient times and is also the best raw material for making handicrafts. During the Ming and Qing Dynasties, the royal family of the court advocated making all kinds of learning tools with this kind of wood, and the craft was fine, just like the rhinoceros horn. Because Daphne is precious and rich in rotten wood, there are few excellent materials for carving with it. Therefore, in the auction market, once there are large items made by Daphne, there will often be surprising performances.

At present, there are more and more fakes in Daphne, and the real Daphne can become more and more fragrant with time, while the heavy fragrance of fakes will soon disappear and fade. The real Daphne odora, with the passage of time, the color will become darker and darker, and there will be more and more grease lines, which is an important criterion to judge the authenticity.

Aquilaria sinensis is a kind of balsam invaded and parasitized by Daphne family fungi, which has been changed and deposited for many years. It is a precious medicinal material, which has the functions of expelling filth and evil spirits and calming the liver. Now it is very rare.

Ancient books have long recorded that Hainan is rich in high-quality agarwood. In the Song Dynasty, Hainan Aquilaria sinensis gradually became a commodity from the imperial tribute, and the trend of over-exploitation became more and more fierce, "millions of dollars".

According to its formation, Aquilaria sinensis can be generally divided into six categories: soil sinking, water sinking, lodging, ant sinking, living sinking, white wood and so on. The mysterious and strange fragrance of agarwood embodies the aura of heaven and earth for thousands of years. Some are rich, some are quiet, some are warm and some are clear. ...
