Jin Sinan is a very precious and high-quality wood. Because wood has a strong luster (especially the bright spots with nail marks when planing, so some people call it Jin Sinan), even if it is not painted, it will get brighter and brighter. The bark is thin and has dark punctate lenticels; There is a black annular layer where the endothelium meets the wood. Because the earlier nanmu is mostly big material, and the tree has few straight joints, smooth texture and is not easy to deform, and it does not rot for thousands of years, ranking first among white trees other than hardwoods, and its wood value is also above some hardwoods.
Question 2: What is the golden thread in Jin Sinan wood? What is the gold thread of nanmu?
1. The golden thread of Phoebe bournei is that when Phoebe bournei breaks, the nutrient solution delivered before will remain in the fiber cells, and these nutrient solutions will quickly form a crystalline state. When the wood is placed in the sun, you can see the glittering gold thread. These gold wires are actually formed by the oxidation of tree gum, which is constantly oxidized with the accumulation of years and the contact with air. So Nanmu is called Nanmu because of its gold thread.
Because nanmu grows slowly, the annual rings of nanmu are like the waterline of filar silk. The material is yellow with a little light green, and the golden light flashes like satin. It looks amazing!
There is a Longmuge website in Shanghai, which contains various handicrafts and collectibles such as lobular rosewood, Huang Huali, Jin Sinan and agarwood. Interested friends can go and have a look.

Question 4: What is the wood of nanmu gold wire? For friends who like to collect gifts, the word "Nanmu Jinsi" should be a heavyweight word. The treetops and roots of nanmu gold wire are basically the same thickness, with few nodes. The wooden parts are generally yellow and golden yellow, with faint fragrance, delicate texture, hardness and wear resistance. There are faint bright wires and bright spots on the plane surface, which shine even without any paint. The biggest advantage of nanmu is that it does not rot or deform for thousands of years.
Identification points of Phoebe bournei: The biggest feature of Phoebe bournei is its strong corrosion resistance, which will not rot after being buried underground for thousands of years, so most of the emperor's coffins are made of Phoebe bournei.
Identification of nanmu: Jin Sinan wood has the fragrance of nanmu, which can repel mosquitoes and insects. Modern experiments have also proved that Phoebe bournei can resist the erosion of rotten bacteria and termites. In addition, the golden nanmu is also resistant to the decay of marine wood-boring animals, so the royal bookcases in past dynasties must be golden nanmu furniture.
Identification points of Phoebe bournei: the texture of Phoebe bournei is exquisite and magnificent, delicate and abnormal, moist and soft, with a yellowish brown and green new section and strong luster. The most obvious feature is that it emits a little golden light under the light, but it is quiet and innocent, quiet and low-key.
Identification points of nanmu: Nanmu is mild in nature, neither hot nor cold in Leng Xia in winter, and does not harm the body, while other hardwood furniture does not have this excellent characteristic. Therefore, nanmu is often used to make desks, tables, arhat beds, cabinets and bookshelves in the palace, and can also be used to decorate cabinet doors or make stationery for study.
Five points of identification of Minnan: Because the wood grain in Jin Sinan is straight, it is not easy to deform, and the warping phenomenon is rare. Wood has small expansion and contraction, moderate hardness and good nail force.
Identification points of nanmu gold thread 6: The utensils made of nanmu gold thread are beautiful in shape and will not feel hard. Golden nanmu furniture pays attention to wood color, that is, it is not painted or waxed, because after painting and waxing, the color of golden nanmu will turn black and lose its original color.
Identification points of Phoebe bournei: Ming and Qing furniture made of Phoebe bournei is simple in texture, soft and tough, and simple and elegant in temperament.
In fact, it is not difficult to identify Minnan. There is a kind of gold thread in Minnan, because the name Minnan is not a professional technical name. This kind of wood is a folk saying from the emperor to the people in history. First of all, it must be determined that it is Phoebe bournei. There are about 34 species of Phoebe bournei in China. As long as the golden thread is obvious, it can be identified as Phoebe bournei, but Phoebe bournei is very precious, and Phoebe bournei is a national protected tree species. Phoebe bournei not only has small expansion and contraction; It has strong corrosion resistance. Experiments have proved that it can resist the erosion of rot fungi and termites, and it can also resist the decay of marine wood-eating animals. Good nail grip in hardness, low strength and impact toughness; The drying condition is also very good, and it does not become warped or cracked. The furniture presented by golden nanmu is beautifully shaped, and there are countless gold threads under the light.
Phoebe bournei wood is hard, corrosion-resistant, fragrant, with few straight nodes, smooth texture and not easy to deform. It is a high-grade carving and furniture material. There are three simple ways to identify Phoebe bournei: one is to smell it with your nose, which belongs to Lauraceae, and the newly cut material has a faint smell similar to but different from Cinnamomum camphora; Second, weigh it by hand, it has high density, heavy feel and weight comparable to mahogany; Third, with the eyes, Jin Sinan's new materials are generally light yellow in color, golden in year and lavender in outer layer.
Question 5: What kind of golden nanmu is the best? Phoebe bournei is a kind of precious wood with high value, and it is very good to make wood carvings and furniture. Phoebe bournei is a precious wood unique to China, mainly produced in Yunnan, Guizhou, Sichuan, Hunan, Hubei and other places, among which Sichuan is the best, and all the royal timber in Ming and Qing Dynasties is collected from Sichuan, followed by Guizhou. What are the species of Phoebe bournei? Let me introduce you! Jin Sinan includes Phoebe bournei, Phoebe bournei, Phoebe bournei, Phoebe Lichuanensis, Phoebe chekiangensis and Machilus Yunnanensis, Phoebe nanensis and Phoebe houYe Nan. Ordinary nanmu, a new sawn wood section called "Nanmu" in the industry, can still see a little golden light flashing under the reflection of light. In fact, there are obviously more crystals in the "Jin Sinan" wood grain than ordinary nanmu. From a proper angle, you can see that there is a strong reflection, and the gold thread is bright and bright.
At present, there are mainly three kinds of Phoebe bournei on the market. One is Phoebe bournei, which is banned by the state and the number is extremely rare. The second is the maintenance and demolition of the ancient temple, and the old golden nanmu unearthed from the ancient tomb. Third, ebony nanmu, which is buried deep underground due to changes in rivers and the earth's crust, is mainly produced in Sichuan. Not all nanmu with golden thread are nanmu with golden thread, because most nanmu have golden thread more or less, and not all nanmu can become nanmu with golden thread after years of washing. Nanmu gold wire is actually a crystal formed by long-term oxidation of nanmu cell fluid, which can reflect light from many angles. Golden nanmu, with golden thread in the wood grain, is the best of nanmu. What is even more rare is that some nanmu materials form natural landscape figure patterns, and the crystallization in the "Jin Sinan" wood grain is obviously more than that in ordinary nanmu. From a proper point of view, we can see that the light is strongly reflected, bright and bright, and the elegant aroma is slightly stronger than that of ordinary nanmu. After a long time, the wooden surface of Jin Sinan will become dark and the color will be black and gray. Phoebe bournei, the wood is purplish, fragrant and the texture is beautiful. Nanmu wood is soft and often used to make furniture. It is difficult to distinguish Nanmu, Jin Sinan and Nanmu accurately according to the characteristics of naked eyes, which is difficult to distinguish macroscopically, but it can be distinguished microscopically.
Question 6: What's the difference between Phoebe bournei and Daphne? Jin Sinan is a general name for some nanmu (including Castanopsis fargesii, Zinan, Minnan and Runnan). ) with gold thread and satin. In ancient and modern times, Jin Sinan was another name for Zinan. Jin Sinan is a rare wood unique to China, with stable wood, no warping and cracking, and durable; In addition, it is mild in nature, warm in winter and cool in summer, and its fragrance is fresh and pleasant. Historically, it was specially used in the buildings and furniture of royal palaces and a few temples. Aquilaria sinensis is actually a mixture of resin and wood fiber secreted by fragrant trees in the case of trauma or disease. It has many functions, for example, it can be used as medicinal materials, spices, decorations, Buddhist gods and so on.
Question 7: What's the difference between gloomy Phoebe bournei and Jin Sinan forest? Gloomy Jin Sinan has been underground or underwater for about 1000 years, and so is Jin Sinan now.
Question 8: Which is better, the golden nanmu or the gloomy nanmu bracelet? First, explain what golden nanmu and gloomy nanmu mean respectively: Jin Sinan, as everyone knows, so does gloomy nanmu. Simply put, it was buried underground for thousands of years and carbonized to a certain extent. The Jin Sinan tree in the gloomy forest is gloomy Jin Sinan.
Let's talk about choice first. Jin Sinan's dark wood is more expensive than Jin Sinan's old material, but for your own use, I recommend you to buy Jin Sinan, which is bright and shiny. Dark wood is not suitable for home use.
Question 9: Is Phoebe bournei very light? Yes, the reason is:
On the one hand, because the golden nanmu is not a specific quality, because the wood of nanmu is oxidized for a long time, and the gold thread is formed on the surface with a small probability, so it is lighter.
On the other hand, because the plant of nanmu belongs to cork, its weight is very light, so it has the characteristics of light weight and no pressure on hands.
