How many kinds of sequoias are there?

Question 1: What kinds of redwoods are there?

Species of sequoia

According to national standards, the range of "Sequoia" is determined to be 5 genera and 8 categories. Five genera are named after dendrology genera, namely Pterocarya, Dalbergia, Elaeagnus and Aralia. Eight categories of wood are named after their trade names, namely rosewood, rosewood, rosewood, rosewood, rosewood, ebony, ebony, striped ebony and wingwood. At the same time, redwood refers to the heartwood of these 5 genera and 8 categories of wood, and heartwood refers to the central part of the tree without living cells. Other wooden furniture cannot be called mahogany furniture.

Mahogany is a tropical wood, belonging to Dalbergia, mainly produced in India, and also produced in Guangdong, Yunnan and Nanyang Islands in China. It is a common and precious hardwood. Redwood is a common name in Jiangsu, Zhejiang and North China, and rosewood in Guangdong.

In the media, we often see reports that illegal manufacturers use new mahogany as old mahogany to deceive consumers. Many consumers will ask: mahogany is mahogany, what is the difference between old and new? In fact, there are not only old and new redwoods, but also great differences in the value of old and new redwoods. In use, you will also find that the quality gap is also very large. So, what is old mahogany? What's the difference between old and new mahogany?

The difference between old redwoods and other redwoods

Old mahogany, as its name implies, is a kind of mahogany that has gone through a long time. In the national standard, it is called acid branch, which is mainly produced in Southeast Asian countries such as Laos and Thailand. Before the late Qing Dynasty and the early Republic of China, China also existed in Guangxi, Yunnan and other provinces, and disappeared completely after the Republic of China. Its wood is hard and delicate, can sink in water, and generally needs to grow for more than 500 years before it can be used. The most obvious difference with other wood is that its wood grain is often sandwiched with dark brown or black stripes in crimson, giving people an antique feeling.

Old redwoods not only grow for a long time, but also have been washed away for hundreds of years after being cut down. Nowadays, old mahogany generally refers to mahogany imported from Nanyang in the middle of Qing Dynasty. Old mahogany has a wide width, slender brown eyes, and the proportion is between mahogany and yellow gorgeous.

Comparison of materials and colors of old and new mahogany.

In terms of color, the old rosewood is darker in color, mostly purplish red, and some colors are similar to rosewood, but the color is lighter, the texture is delicate, the brown eyes are obviously less than the new rosewood, and the density and feel are excellent. The color of the new mahogany is generally Huang Chi. Compared with the old mahogany, the wood grain and color have a "tender" feeling, but the texture and feel are not as good as the old mahogany.

Why is the difference so big? It turns out that the life of wood has not ended because of being cut down, and its internal fine structure has been changing, but it is difficult for people to detect it. With the passage of time, the internal structure of mahogany will become denser and denser, the hardness and specific gravity will become higher and higher, and it will sink when it enters the water, and its deformation resistance will become stronger and stronger.

The new mahogany is generally baked to meet the use requirements, but manual technical treatment can not shake the internal structure of the material, and in the long-term use process, it often produces subtle deformation, thus affecting the collection value.

What is old mahogany?

"Mahogany" has little to do with a certain tree species at first, and it is a general term for high-quality hardwood that appears red in a certain period since Ming and Qing Dynasties. The materials used are rosewood, rosewood, rosewood, etc., which are yellow-red or purple-red to varying degrees. When people have no intention of distinguishing what kind of trees they are, they are used to calling them redwoods. Zhao's antique guide emphasizes that redwood is a special tree species. Chapter 29 of the book says: "Only the so-called redwoods in the secular world are proper nouns of wood, not mahogany characters", which proves that one kind of wood in the book refers to old redwoods. Old mahogany is produced in Indochina Peninsula, and also grows in China and Yunnan. Its leaves are oblong, white and five petals, and its color is red. "In addition to rosewood, mahogany is the best wood", which is the evaluation of old mahogany in the book.

Old mahogany and red rosewood cannot be confused. Red rosewood refers to a large category of wood, including Dalbergia odorifera, Dalbergia odorifera, Dalbergia odorifera and so on. Old rosewood is just a kind of rosewood, namely Dalbergia odorifera. Although they all belong to Dalbergia, the old rosewood is purple in color, clear and changeable in texture and fine in structure, which is incomparable to similar rosewood.

The next process of making furniture from old mahogany uses the same method as rosewood-waxing, and never use the method of ordinary rosewood-painting. Because old mahogany is full of wax, it can be smooth and lubricated by rubbing wax, and its luster is lasting, giving people a pure and implicit aesthetic feeling. If modern painting techniques are adopted, > >

Question 3: How many kinds of sequoias are there? What is the difference? Redwood does not refer to all redwoods, nor to a kind of wood, but to the current domestic mahogany furniture materials. According to the national standard of mahogany, only 5 genera and 8 categories of commercial timber can be called mahogany. Furniture and handicrafts made of mahogany have always been very popular products. Mahogany furniture has always been a symbol of dignity and wealth in China. In recent years, with the remarkable improvement of people's living standards, mahogany furniture has gradually entered the homes of ordinary people. However, in the face of a large number of mahogany furniture in the market, people are always afraid of buying fakes themselves, and there is no evidence for manufacturers and distributors, and even the law enforcers of technical supervision departments can't rely on it. In order to standardize the current materials of mahogany products and promote the healthy development of the market, the State Bureau of Quality and Technical Supervision recently officially issued the national standard of Mahogany, and stipulated that this standard will be implemented from August 1 2000. To this end, the reporter visited Mr. Yang Jiaju, the first drafter of the national standard of "Redwood" and an associate researcher at the Wood Industry Research Institute of the Chinese Academy of Forestry. This standard is mainly formulated to correct the name of "Sequoia".

Mr. Yang Jiaju said that it is true that everyone knows that mahogany furniture began in the Ming Dynasty. In history, Zheng He made seven voyages to the Western Seas, and once arrived in Vietnam, Java, Sumatra, Sri Lanka, India and the east coast of Africa, bringing China's silk and porcelain to foreigners. What he brought back was mainly mahogany, which was only used as ballast because of its heavy weight. After mahogany was introduced into China, some skilled craftsmen used it to make furniture, which resulted in the famous "Ming-style furniture" at home and abroad. Today, more than 98% of sequoias in China are still imported. Due to excessive logging abroad for many years, the precious mahogany resources are decreasing year by year, so the supply of mahogany in China is relatively tight. Some furniture manufacturers either buy old mahogany furniture for restructuring, or import other wood with similar quality as a substitute to make a profit. In this way, a wide variety of mahogany furniture appeared on the market, which puzzled consumers for some time. Not only that, the name "rosewood" itself has not been scientifically and strictly defined, and it is very confusing to use. Common sayings about rosewood in the market include rosewood, fragrant rosewood, old rosewood, new rosewood, rosewood, Venus rosewood, ox hair rosewood, pear, new rosewood, huanghuali, purple pear, red rosewood, black rosewood, white rosewood, ebony and pear. Moreover, there are homographs or homonyms in mahogany. For example, some people call part of the curly texture of sandalwood rosewood ox hair rosewood, and the heartwood full of gum is called Venus rosewood. Actually, it's all the same kind of wood. These nonstandard names have brought great difficulties to consumers and market managers in identifying mahogany furniture, so everyone urgently requires the relevant state departments to give an authoritative statement. We have formulated this national standard of "redwood" in order to correct the name "redwood".

"Mahogany" is a general term for eight commercial materials in the standard.

Mr. Yang Jiaju said that mahogany is the common name of mahogany furniture materials in China at present, but we have made great efforts to scientifically define its scope. Firstly, this paper studies the furniture fragments and wood characteristics of Ming and Qing Dynasties from the perspective of wood anatomy. At the same time, it extensively refers to the correctly named wood specimens and materials at home and abroad, and also considers the acceptance habits of the masses. For the redwood tree species in the income standard, we should not lose too much, and we should call all redwoods in general, and we should not be too strict, that is, we should not be divorced from the reality of classical furniture in Ming and Qing Dynasties. Therefore, according to the principles of scientificity, historical continuity and feasibility, the national standard of Mahogany defines the scope of Mahogany as 5 genera and 8 categories. The five genera are named after the genera of dendrology, namely Pterocarya, Dalbergia, Persimmon, Asparagus and Tilia. Eight categories of wood are named after their trade names, namely rosewood, rosewood, rosewood, rosewood, rosewood, ebony, ebony, striped ebony and wingwood. At the same time, Mr. Yang particularly emphasized that mahogany refers to the heartwood of these 5 genera and 8 categories of wood, and heartwood refers to the central part of the tree without living cells.

The identification of "mahogany" needs to find a professional department.

When it comes to how consumers can identify the authenticity of mahogany furniture, Mr. Yang Jiaju said that there is no simple method at present. Because of simple visual inspection and touch, it is difficult to tell whether it is real mahogany. Even experts who identify ancient furniture will inevitably make mistakes. Although mahogany has some common characteristics, such as hard wood, heavy weight and delicate texture, some miscellaneous wood and hardwood that do not belong to mahogany also have the same characteristics. Therefore, find a professional department to carry out mahogany furniture >>

Question 4: What are the kinds of redwoods? Types of Sequoias in China According to national standards, Sequoias are divided into two families, five genera, eight categories and thirty-three species. Two families: Leguminosae and Persimmon. The five genera are named after the genera of dendrology, namely Pterocarya, Dalbergia, Persimmon, Asparagus and Aralia. Eight categories of wood are named after their trade names, namely rosewood, rosewood, rosewood, rosewood, rosewood, ebony, ebony, striped ebony and wingwood. Mahogany refers to the heartwood of these five genera and eight categories of wood, that is, the center of the tree and the part without living cells. Other wooden furniture cannot be called mahogany furniture.

The so-called "sequoia" has little to do with a certain tree species at first. It is just a general term for high-quality hardwood that has appeared in a certain period since Ming and Qing Dynasties. The materials used are rosewood, rosewood, rosewood, etc., which are yellow or purple to varying degrees. When people have no intention of distinguishing what kind of trees they are, they are used to calling them redwoods.

Rosewood: produced in subtropical areas, such as Southeast Asia such as India. China's Yunnan, Guangdong and Guangxi all have a small amount of production. Wood is shiny and fragrant, and turns purple-red and brown after being exposed to the air for a long time. It is interwoven with arts and sciences, with dense structure, corrosion resistance, strong durability and hard, heavy and delicate materials.

Huang Huali: It is a rare and unique tree species in China. Wood is shiny and spicy; Arts and sciences are interlaced, with thin and uniform structure and corrosion resistance. Strong durability, hard and heavy material and high strength.

Rosewood: distributed in tropical regions of the world, mainly produced in Southeast Asia, South America and Africa. Among them, African hedgehog rosewood accounts for more than half of the transaction volume of mahogany furniture in China, and famous brands include Meitan, Kyocera and Nianhong. ). Hainan, Yunnan, Guangdong and other places have introduced and cultivated. Wood is uniform in color, from light yellow to dark reddish brown, with dark stripes, luster, slight or obvious faint fragrance, staggered in texture, fine and uniform in structure (slightly coarse in South America and Africa), durable, hard and high in strength, and usually floats in water. Among rosewood produced in Southeast Asia, Thailand is the best, followed by Myanmar.

Mahogany: Tropical and subtropical regions, mainly produced in Southeast Asian countries. The color of wood is uneven, the heartwood is orange, light reddish brown to dark brown, and dark items are obvious. Wood has luster, sour taste or sour fragrance, arts and sciences crisscross, high density, greasy, hard and wear-resistant.

Chicken wing wood: it is distributed in the subtropical region of the world, mainly in Southeast Asia and South America, and is named after its texture is similar to "chicken wings". The texture is not clear, the color is abrupt, the wood is odorless, and the growth rings are not obvious.

Question 5: What kinds of sequoias are there? They are: rosewood, rosewood, rosewood, wingwood, beech and ebony.

There are two kinds of acids: black acid and red acid.

Black rosewood: heartwood is purple-black, purple-red, deep purple, yellow-brown, reddish-brown, with black stripes, in which Dalbergia odorifera broad-leaved stripes are wider and farther apart; The stripes of Dalbergia odorifera in Brazil are narrow and obvious.

Red rosewood: the growth rings are obvious, and the heartwood is dark reddish brown, orange reddish brown, purple reddish brown or dark purple brown, often with dark brown winter stripes or dark reddish brown stripes. The tube hole is visible or obvious to the naked eye. The new cut surface of Dalbergia odorifera has a pungent smell and sour taste. Can be processed into necklaces and bracelets. The texture is very hard, if the saw is fierce, it will hit the teeth, and the process of planing is more difficult. This is the best wood for making furniture and handicrafts.

Rosewood: The growth rings are obvious, and the heartwood is reddish brown, among which Indian rosewood is golden yellow, the heartwood of big fruit rosewood is orange red, brick red or purple red, and the new section of color-changing rosewood is pale yellow.

Red sandalwood: also known as purple elm and longmu. This kind of tree grows slowly and its growth rings are not obvious. The new section of heartwood is orange-red, but it turns to deep purple or dark purple for a long time, and there are often light colors and purple-black stripes; The tube hole is invisible to the naked eye, with obvious scratches, and the water leaching solution of sawdust is purple; The aroma is missing or weak, the texture is staggered, partially curled, and the specific gravity is very large, which can almost sink into the water; After making furniture or handicrafts, there is no need to paint and paint, and it will never change color. The hand feels delicate and comfortable, and the vision is profound and elegant. Very expensive, not by volume but by weight, 30-40 yuan per 500g, not easy to buy.

Gall wood: also known as shadow wood, is actually a nodule of some trees. When it grows to a certain size, it is sawed off and used for processing. Often because of different tree species, the pattern is different.

Ebony: the growth rings are not obvious, and the heartwood is all black. The tube holes are slightly visible to the naked eye, odorless, thin in structure, and usually straight or slightly staggered and heavy in texture. It is often matched with other wood with different colors and beautiful textures. Redwood is divided into: rosewood, rosewood, rosewood, chicken wing wood, eucalyptus and ebony.

There are two kinds of acids: black acid and red acid.

Black rosewood: heartwood is purple-black, purple-red, deep purple, yellow-brown, reddish-brown, with black stripes, in which Dalbergia odorifera broad-leaved stripes are wider and farther apart; The stripes of Dalbergia odorifera in Brazil are narrow and obvious.

Red rosewood: the growth rings are obvious, and the heartwood is dark reddish brown, orange reddish brown, purple reddish brown or dark purple brown, often with dark brown winter stripes or dark reddish brown stripes. The tube hole is visible or obvious to the naked eye. The new cut surface of Dalbergia odorifera has a pungent smell and sour taste. Can be processed into necklaces and bracelets. The texture is very hard, if the saw is fierce, it will hit the teeth, and the process of planing is more difficult. This is the best wood for making furniture and handicrafts.

Rosewood: The growth rings are obvious, and the heartwood is reddish brown, among which Indian rosewood is golden yellow, the heartwood of big fruit rosewood is orange red, brick red or purple red, and the new section of color-changing rosewood is pale yellow.

Red sandalwood: also known as purple elm and longmu. This kind of tree grows slowly and its growth rings are not obvious.

Ebony: the growth rings are not obvious, and the heartwood is all black. The tube holes are slightly visible to the naked eye, odorless, thin in structure, and usually straight or slightly staggered and heavy in texture. It is often matched with other wood with different colors and beautiful textures.

Question 6: What kinds of sequoias are there? What kinds of redwoods are there? They ranked 1- Huang Huali and rosewood.

The first kind of redwood is Huang Huali and rosewood. Let's look at Huang Huali first. Huanghuali, also known as Dalbergia odorifera and Hainan Huanghuali, is the most precious wood in China and the main material of hardwood furniture in Ming and Qing Dynasties. Huang Huali is yellow in color, delicate in texture, soft in texture and fragrant. Hainan Island's unique tropical monsoon island climate provides a suitable growth environment for it. Rosewood is a kind of long green subtree, which is produced in India and Southeast Asia. The texture of rosewood is like forged jade, delicate, dense and irregular crab claw texture. Furniture made of rosewood is not painted, deformed and perishable. After the Qing Dynasty, the court listed rosewood as the first choice of court furniture products.

The category of redwood ranks second-ebony, ebony and African rosewood.

Now that we know the best species of redwoods, which ones rank second? It's black rosewood, ebony and African rosewood. Black rosewood mainly includes Belizean Dalbergia, Amazon Dalbergia, Brazilian Dalbergia, African ebony, Lushi Dalbergia, broadleaf Dalbergia, black Dalbergia and knife Dalbergia. , and the main materials of furniture are hardwood Dalbergia, African ebony and Dalbergia Lushi. Ebony is produced in India, Indonesia, Thailand, Myanmar and other countries. Its heartwood is black, irregular black. Its structure is fine and uniform, the material is hard and heavy, and it has a sense of grease. African rosewood, also known as safflower pear or Shaw rosewood, is a tree belonging to Pterocarya of Butterfly Family. It has a shiny brightness and a slight fragrance.

Red rosewood branch-a third-class redwood tree species

Red rosewood is a tropical evergreen tree species, which is called "old redwood" in northern China. The new red rosewood has a unique sour aroma of red rosewood, so it is called red rosewood. Mainly distributed in tropical areas of Southeast Asia and Central and South America. Red rosewood mainly includes Dalbergia microphylla, Dalbergia Auschwitz, Dalbergia Central America, Dalbergia tomentosa, Dalbergia flag leaf, Dalbergia Saichuan and Dalbergia Barry. The main materials of furniture are Auschwitz Dalbergia and Dalbergia odorifera. Although rosewood is in a slightly inferior position in the ranking of mahogany varieties, it is also a very precious mahogany after all.

Rank 4 of redwood tree species-Pterocarya cristata

The fourth kind of redwood is wingleaf wood, also called "Qizi wood". Its wood texture is similar to chicken wings, so it is called wingleaf wood. This kind of wood is produced in Guangdong and Hainan Island of China. Chicken wing wood has clear interlaced texture, abrupt color, no fragrance, inconspicuous growth rings, bright yellow when cut open, and brown or dark brown when exposed to air. It is mainly divided into African cliff beans, white cliff beans and iron sword beans.

The fifth redwood tree species-rosewood in South America and Africa

South American rosewood is distributed in Mexico, Cuba and tropical South America. Its heartwood is reddish brown and often has dark stripes. The boundary with sapwood is obvious. African rosewood grows in the rainforests of West and East Africa and in the tropical areas of Central and West Africa. It has good mechanical properties, strong durability and good wear resistance, and is an ideal material for senior joinery, furniture and cabinets. Rosewood in South America and Africa ranks last in the category of mahogany, but it is also a kind of high-quality mahogany.

Question 7: What kinds of mahogany furniture include rosewood, rosewood, ebony, chicken wing wood, rosewood and so on? The difference between heartwood and sapwood is obvious, and sapwood is narrow and gray. Heartwood is yellow-red to red, which will turn purple when exposed to air for a long time. Because of its slow growth, hard material, long growth period of hundreds of years and fragrance, mahogany is very precious and has certain collection value. Different redwoods have different characteristics.

red sandalwood

Alias Qinglong wood, it generally grows in subtropical areas. It is an evergreen tree, which can grow to more than 15 meters. The wood is hard and reddish, and rosewood sinks when it enters the water. In mahogany furniture, it is also the most advanced wood, with purple and black, which is most suitable for making furniture and can also be used for carving works of art. Color determines that it can be polished, waxed and not colored. Because it has a special fragrance, all kinds of things made are cherished by people.

Rosewood is also divided into rosewood (thick as old rosewood, slightly twisted, light in color, easy to fade, thicker in texture than other rosewood, not suitable for carving, not as expensive as Venus rosewood and bloodsucking rosewood), ox hair rosewood (brown eyes are very thin and long, slightly curved, very much like ox hair, and the luxury is second only to Venus rosewood, which is mostly used for furniture) and bloodsucking rosewood (deep purple). The texture is delicate and oily, especially near sapwood, and irregular dark scarlet zebra stripes of different lengths often appear, which is quite interesting)

Acid tree

Rosewood is also one of the classifications of mahogany furniture. The wood structure is fine, the wood feels smooth, shiny under the light, and the color is dark. Most of them are bordeaux, and the sapwood is obviously different. Sapwood is yellowish white to yellowish brown, and some trees are brown. Heartwood orange, light reddish brown, reddish brown, purplish red, purplish brown to dark brown; Wood color is uneven and dark stripes are obvious.

Rosewood has a sour taste when it is just cut (a few are roses), and its structure is thin, uniform, corrosion-resistant and durable. Large output, high output, large trunk diameter and beautiful color patterns are widely used in furniture making.

There are three kinds of rosewood: black rosewood, red rosewood and white rosewood. And a few sour branches.

ebony

Ebony, also known as ebony, is formed by carbonization for thousands of years under the conditions of hypoxia and high pressure and under the action of microorganisms such as bacteria, so it is also called "carbonized wood". There are many kinds of ebony, such as Salix psammophila, Phyllostachys pubescens, Cinnamomum camphora, Phoebe bournei, Toona sinensis, Taxus chinensis, Coriaria sinica, Tamarix chinensis, Phellodendron amurense, Sophora japonica and Sandalwood.

Ebony has many cracks, generally only small handicrafts are made, and there are few large pieces of furniture circulating; Ebony is non-corrosive, immortal and moth-eaten. It is an excellent material for making high-grade small furniture, temple Buddha statues and handmade works of art. Complete sets of ebony furniture are very rare and expensive.

red sandalwood

The wood color of Huanghua pear is golden and moist, the heartwood color is reddish brown or dark brown, and it has the texture of repeated horns. The texture is very beautiful, like ghost face or raccoon spot, also known as "flower raccoon". Wood is extremely stable and does not deform, crack or bend in hot and cold weather. It has certain toughness and is suitable for all kinds of special-shaped furniture. So there are many mahogany furniture made of mahogany on the market.

Wenge

Tangential section, a heartwood, is named after its chicken wings. Wood is hard, and the colors are divided into three colors: black, white and purple. Natural and beautiful texture.

Taiwan Province rosewood (mainly produced in Myanmar and Thailand), Taiwan Province rosewood (produced in South and Southeast Asia, Yunnan, Fujian, Guangdong and Guangxi in China) and African rosewood (produced in Africa).

Question 8: How many kinds of sequoias are there? According to the principles of scientificity, historical continuity and feasibility, the national standard for mahogany defines the scope of mahogany as five genera and eight categories.

In this "five genera and eight categories":

Five genera are named after dendrology, namely Pterocarya stenoptera, Dalbergia Dalbergia, Persimmon, Asparagus and Tilia amurensis, and * * * currently includes 33 kinds of wood.

Eight categories

1. Sandalwood rosewood

2. rosewood Vietnamese rosewood Andaman rosewood hedgehog rosewood Indian rosewood big fruit rosewood bagged rosewood bird foot rosewood

3. Dalbergia odorifera

4. Black rosewood knife-shaped black Dalbergia black Dalbergia broadleaf Dalbergia Lushi black Dalbergia African black wood Brazil black Dalbergia Amazon Dalbergia Belize Dalbergia

5. Red rosewood: Brazil's scent, scent, scent, scent, Central America's scent, scent, scent, scent, scent.

6. Chicken wing wood, African cliff bean wood, white flower cliff bean wood, iron knife wood

7. Ebony ebony thick petal ebony ebony hair growth medicine ebony Pons ebony.

8. striped ebony Sulawesi ebony Philippine ebony

Question 9: How many kinds of sequoias are there? What are the prices of different kinds? Not long ago, the owner of a mahogany furniture factory made a ranking of mahogany materials on this website. After that, this website also heard a little different voice. Now, please ask Xinjian Ma, general manager of Beijing Ma Hong Redwood Furniture Company, to make a ranking and see what he says: tied for the first place: Hainan Huang Huali and Redwood. If only from the perspective of furniture, lobular rosewood will be better, whether it is soft or hard or fine. As far as medicinal value is concerned, it is Huang Huali, which has fragrance and can adjust the environment. Second place: red rosewood The red rosewood mentioned here must be authentic red rosewood, which is the kind of 6.5438+0.5 million yuan a ton on the market at present. (Authentic rosewood, the best in Laos. Vietnam can, but the semi-finished products imported from Vietnam can't, because they are semi-finished, sir, and they should be dried after delivery. The real process should be drying before production. It reverses the procedure, so the semi-finished product is not good enough. Tied for third place: striped ebony and blackcurrant. The striped ebony here refers to Indonesia. Vietnam's striped ebony is worthless, and the price of raw materials is about half cheaper than that of Indonesia. The black rosewood mentioned here is also called big leaf rosewood. In fact, it was originally called big leaf rosewood. Later, the national standard was introduced. In the national standard, the big-leaf rosewood is called black rosewood, so the current standard name is black rosewood. Fourth place: Elaeagnus angustifolia does not have this name in the national standard, but Myanmar calls this tree species Elaeagnus angustifolia. At present, the market price is about 8000-9000 yuan per cubic meter, which is produced in Myanmar. There is no rosewood red or rosewood oil. Close to Dalbergia odorifera in the national standard. (From the wood type, the white acid branches are larger and the red acid branches are smaller, so it is not convenient to measure when they are small. Therefore, white sour branches are priced by meters, and red sour branches are priced by tons. In contrast, white rosewood is about half cheaper than red rosewood. ) tied for fifth place: chicken wing wood, rosewood. The wingwood mentioned here refers to Burmese wingwood (Baihua Cliff Leguminosae), and the rosewood mentioned here is also called rosewood. The price difference between the two materials is not too much, but the workmanship is different. Because the production of wingwood requires more labor and materials than rosewood, the price of wingwood is also more expensive than rosewood. Identification of mahogany furniture mahogany furniture is internationally renowned and valuable furniture. Its solemn color, delicate and beautiful texture, hard and heavy wood, good moisture resistance and durability have always been loved by people. Pay attention to the following points when buying mahogany furniture: (1) Understand the texture of mahogany furniture. Mahogany furniture is only one kind of hardwood furniture, and rosewood, rosewood (Hainan sandalwood), chicken wing wood and rosewood all belong to hardwood furniture, but now many people are used to mixing all hardwood furniture with mahogany furniture. If you know that the material of furniture is one of the above-mentioned wood, then this kind of furniture is mahogany furniture. If the furniture is made of rosewood and mahogany, it is "authentic" fine mahogany furniture, especially rosewood. Rosewood is generally red, and wood is harder and heavier than mahogany. The wood grain is finer, more oily and more beautiful, but this opportunity is rare. At present, rosewood furniture in China is mainly rosewood and rosewood. The wood is medium, the color is red, it is lighter and brittle than mahogany, and the texture is thicker than mahogany. Because the diameter of rosewood is less than 33 cm, when a large area of wood (such as chair seats) is needed, rosewood will be used instead. So sometimes it is found that a piece of furniture is made of two kinds of wood, but this is a normal process, so don't worry when choosing. (2) Distinguish true and false mahogany furniture from wood grain and weight. Real mahogany furniture itself has a variety of natural reds, such as purple, yellow, crimson, crimson and so on. The wood grain is simple and beautiful, elegant and fresh. After making furniture, although it is colored, the wood grain is still clearly discernible; However, imitations are generally thicker in color, often white, and have no texture. Real mahogany furniture is solid and compact, heavier than general miscellaneous wood; The weight of fake mahogany furniture with the same shape and size is obviously different. (3) Pay attention to the style of mahogany furniture. Old-fashioned mahogany furniture is beautiful in shape, and the outline of the furniture has a strong oriental style. But this is only a style of mahogany furniture, and antique is not the only sign of mahogany furniture. Because in modern mahogany furniture, there are many western-style shapes, such as mahogany dining tables, which are very large in shape, and some desktops adopt western-style pull-up structures, which can be extended and retracted at will. For example, the specifications and shapes of sofas have been westernized, and the lines are smooth, which is easy for ordinary families to accept. Another example is the exquisite combination of writing desk, chair, sculpture and style, which is extraordinary in the study; Some desks and chairs are also inlaid with Yunnan marble, ... >>
