Hainan huanghuali, scientific name descending fragrant yellow sandalwood, disc-shaped flower family yellow sandalwood genus species (fragrant branch wood), one of the 29 kinds of mahogany in 8 categories of 5 genera of mahogany national standard, widely used, its wood value is quite high, is a unique precious tree species in Hainan.
The wood products made from it are simple and bright, magnificent, and the color is deep and gorgeous, elegant and noble, durable, and incorruptible for a hundred years. Sea yellow furniture can also emit a quiet wood fragrance for a long time, which is said to be refreshing and avoiding evil.
1. Classification
Hainan huanghuali is generally divided into bran pear and oil pear. Its material, color, and texture also vary greatly depending on the growth area and climatic environment.
Bran pear, also known as pineapple or bran grid, is a tree that grows in the hills of the east, close to the plains, because the land is fertile and grows faster.
Features: Lighter color, slightly worse specific gravity and density, slightly worse oiliness, but good texture.
Color: mainly light yellow, golden yellow, light brown and reddish brown mostly.
Origin: Produced in the eastern and northeastern parts of Hainan, such as Sanya and Haikou.
Bran pear
The texture of the bran pear is gorgeous, the ghost eyes are confused, the layers are clear, beautiful and picturesque, sometimes the spirit instigates, sometimes the return to the sea, there is always a refreshing feeling.
Avocado, also called oil grid or oil, is a tree that grows on the mountains in the west of Hainan Island, because the land is barren and grows very slowly, but the texture is hard and delicate.
Features: darker color, larger, better density, strong oiliness, but general texture.
Color: mainly dark brown, purple, some close to black, some yellow.
Origin: Produced in the western part of Hainan, such as Changjiang, Ledong, Baisha area.
Purple pear
Among the oil pears, purple oil pears are the most famous, and they are also yellow, known as butter pears. Avocado has a strong texture, small pores, high density, many can sink into the water, generally showing a glass texture, to be transparent.
In general, the market price of oil pears is higher than that of bran pears, but whether it is oil pears or bran pears, the best Hainan huanghua pears are beautiful, which makes people have the feeling that "this thing should only be in the sky".
2. Value
First, medicinal value
As a traditional precious wood and the most expensive mahogany species in recent years, Hainan Huanghuali can be described as famous all over the world.
However, what few people know is that it is also a valuable Chinese herbal medicine in the chinese herbal medicine market in various places, which are described in "Materia Medica", "Sea Medicine Materia Medica", "Color Atlas of Practical Chinese Herbal Medicine", "Forest Medicinal Resources", "Chinese Medicine", "Chinese Pharmacopoeia", and "Chinese Pharmacognosis".
The second is the aesthetic ornamental value: a tumor, two numbness and three grimaces
The first to promote tumor scars.
"Tumor people, stay also; swollen people, swollen also" . People have tumors, which is the worst thing, but changing it to trees has become a rare treasure. On which texture of the surface of sea yellow is the most expensive and beautiful, the first is the tumor scar. Once the tree reaches the age, some sick parts can form tumor scars, the so-called "gall wood".
Sea yellow gall wood is more rare than other galls. Because sea yellow itself is a medicinal herb, the taste is spicy and bitter, and it is difficult to get sick. Even if you are sick, the body is empty, and it is even more rare to be able to form a large area of galls in a relatively complete way, so there is very little sea yellow gall material.
This is followed by sesame spots
The so-called sesame dot is a little bit of black spots on the surface that resemble black sesame seeds.
Sesame dots are easier to see in yellower yellow, but they are rare in sea yellow, which may be the reason why sea yellow is denser.
Finally, there is the grimace
Grimaces are divided into narrow and broad senses. Grimace in the narrow sense, that is, the real ghost, that is, the face has complete organs, which is a kind of figuration, very rare, commonly known as "a face worth ten thousand gold".
Generalized grimaces, i.e. cross-sections left behind by the cutting of nodules or branches, are more common, and some are paired in rows and are spectacular.
There are also similar grimaces in rosewood and sourwood, but compared with sea yellow, the gap is larger.
The third is practical value.
All the functions that wood can bear, Hainan huanghuali can be competent, and there is no need to repeat it here.
Third, woodiness
Let's start with density. Almost all wood theorists have set the dry density (equivalent to the specific gravity) of sea yellow gas to be between 0.82-0.94. That is to say, if placed in water, it will not sink into the water, light floating on the surface of the water, heavy semi-floating in the water.
But in fact, industry insiders and old players know that if it is a good oil, many will still sink into the water, indicating that its dry density is greater than 1.
So why is everything wrong in the books? The reason is probably that researchers in the past often used sugar in eastern Hainan for experiments. Due to the slightly poor quality of sugar oil, the dry density of gas can only be in the above range.
Look at the color again. Some people believe that only dark colors, such as purple, brown, and black sea yellow, are considered oily. In fact, the color is yellow and red, as long as the oily feet and pores are fine, the same is more important, and the heavy ones held in the hands are also oily. And the yellow and red oil is more than the dark oil, shining, and it is particularly magnificent.
Finally, look at shrinkage. Most people think that the oil is dense, oily enough, and not easy to crack, but in fact the result is the opposite. Because the pores of oil li are very small, the water in the body is still difficult to disperse after several years, the density is too dense, resulting in no expansion and contraction of the surface, in case of heat expansion and contraction, wet swelling and contraction, there must be gaps.
The surface of bran is thick, the cow hair is more and larger, and it has a shrinkage slit, which can overcome the above cracking factors, so even if it is placed in an air-conditioned room, there are relatively few cracks. However, the cracks in the oil will not be very large, and they will not hinder the appearance after being polished again.
Fourth, maintenance
Sea yellow is born in the wild, does not choose water and soil, and is very easy to survive. Adults are often cut down in the mountains and forests, and the wind and rain soak the sun, so that the surface is thick and clumsy, and it can also be tidalized, making the wood more oily and the fragrance more intense.
After making bright furniture or crafts, you can no longer let it be exposed to the sun and rain, do not put it in a position where the sun is straight, and should not be placed in an environment that is too dry or wet, otherwise it will affect the luster.
In addition, some industry experts said that the finished products of sea yellow cannot be ignored and shelved, otherwise it will be dark but not flexible... Therefore, sea yellow is a person raising wood, wood raising people, the two feel sorry for each other, in order to blend hearts.
5. Collection
Scarce things are more expensive. The amount of sea yellow is so much, and the collection value is of course extremely high. As for artificially planted sea yellow, it is no longer the old material it once was, and there will be no large material output in decades. Sea yellow is better than jade, and it also has medicinal value and has a health promotion effect on people.
