It is a kind of furniture material. Wood comes from tropical areas, Leguminosae and Pterocarya. Mainly produced in Southeast Asia, Guangdong, Yunnan and other places have been introduced and cultivated. 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. Beautiful wood grain, hard and durable material, used for expensive furniture and handicrafts. Hainan sandalwood and gemu also belong to this category. 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.
What kind of mahogany has the best quality?
The first category is Huang Huali and Rosewood.
This refers to China's Hainan Huang Huali and Indian rosewood. These two kinds of wood are basically out of print, and almost all finished furniture has entered the auction collection market. The price of a piece of furniture is hundreds of thousands and millions of RMB. At present, the diameter of young Huanghuali trees in Hainan, China is only 4-5cm, and it will take hundreds of years to become a mature tree. The whole set of furniture (bedroom, study and living room) may be a substitute for African rosewood or other high-grade rosewood (black rosewood). In all fairness, African rosewood is also rosewood, and some people in the market don't agree with its market value and think it can't be compared with Southeast Asian rosewood. Pure African rosewood furniture is extremely rare in the market, and its price is also the most expensive one among the new mahogany furniture at present.
The second kind is black rosewood, ebony and African rosewood.
This is the best mahogany furniture that can be seen on the market at present. Due to the extinction of rosewood in Southeast Asia, black rosewood is generally called rosewood in the market. Bedroom (five pieces) complete sets of furniture are made of ebony and ebony, and the market price is about 10- 15000 yuan, but the quantity is small and scarce. This is mahogany furniture that can be passed down from generation to generation, increasing value and preserving value. Experts of African rosewood and mahogany furniture appearing in the market now do not agree with their value, mainly because African rosewood furniture has been made in a short time, and there are no handed down works, let alone entering the auction collection market. It is believed that with the passage of time, African rosewood furniture will glow with its brilliant brilliance, and its value will be gradually reflected as the first valve collection of new mahogany. A complete set of bedroom furniture (five pieces) made of African rosewood is rare in the Shanghai market every year, and the transaction price is more than 200,000 RMB.
The third kind is red rosewood.
Traditionally, China's old mahogany is made of rosewood from India, Thailand, Vietnam, Cambodia, Laos, southern Myanmar, Indonesia and other Southeast Asian countries. Strictly speaking, bedroom furniture made of rosewood (from Southeast Asia) generally costs 50,000-80,000 RMB, and its price depends on its technology and workmanship under the same material. This kind of high-grade mahogany furniture is not much on the market.
The fourth category is other acid branches.
For example, yellow rosewood and white rosewood in Southeast Asia, including red rosewood produced in areas with poor market recognition (South Africa and southern South China), are the mainstream products of mahogany furniture and are called mid-range mahogany furniture. The market price of a set of bedroom furniture is generally around 350,000-50,000 yuan. As long as it is mahogany furniture, there is no doubt that it is passed down from generation to generation and continues to increase in value. In the history of mahogany furniture in China, the mahogany status of rosewood has never wavered.
Fifth class goods
The fifth category is rosewood, pterygophyllum, Leguminosae rosewood, and white acid branches in South America and Africa. The quality and price of rosewood in Southeast Asia are better than those in South America and Africa. At present, some furniture of Leguminosae rosewood (some of which are iron rosewood) has sold the price of rosewood. In fact, this is misled by the word rosewood, because with rosewood and ebony, rosewood must be a third-class product. Actually, it is not. Dalbergia odorifera is a raw material of mahogany, with unclear concept and various varieties. Among redwoods, except rosewood, rosewood, rosewood and chicken wing wood, the dark red and purplish hardwood of legumes produced in tropical rain forests is collectively called rosewood. Dalbergia odorifera is a modern name, and its concept is inclusive, so it is generally not included in the collection list. ......& gt& gt
Question 2: What does mahogany mean? Mahogany is the main family of refined precious tree species;
First, many names are easily confused.
1962 it has been explained that the materials of Qing classical furniture are red sandalwood, yellow pear, new pear, chicken wing wood, ironwood, ebony and mahogany. Some people say that it refers to red sandalwood, rosewood, rosewood and iron rosewood. 1984 some people say that it mainly refers to red sandalwood, Indian red sandalwood, bagged red sandalwood, Burmese red sandalwood and African red sandalwood, Angolan red sandalwood and Vietnamese red sandalwood; Dalbergia has sappan wood; The genus Ormosia includes Ormosia microphylla, Ormosia microphylla, Ormosia xylocarpa, Ormosia litchi, Ormosia olivacea, Ormosia pyrifolia, Ormosia Taiwan Province and other ormosia trees. There are also many people who call rosewood with light heartwood or red color as huali; The heartwood is crimson or purplish red, which is called rosewood or purple pear. 1986 Some people say that it refers to Dalbergia odorifera, Dalbergia odorifera, Dalbergia Brazil, Pterocarya stenoptera, Pterocarya burma, Andaman, Pterocarya India, Pterocarya India and Pterocarya Africa. Most people use more than 20 names such as rosewood, fragrant rosewood, old rosewood, new rosewood, rosewood, Venus rosewood, Niumao rosewood, rosewood, rosewood, rosewood, ebony, chicken wing wood, Tieli, copper rough, iron rough and so on.
Commercially, in Dalbergia (including a few species of Pterocarya stenoptera), wood with red, maroon or black heartwood is generally called mahogany, and manufacturers are generally called mahogany. But for scented ones (such as Dalbergia odorifera, Dalbergia odorifera, etc. ), it is called fragrant rosewood. One kind of rosewood comes from Hainan Island, and the local people used to call Dalbergia odorifera "rosewood" or "rosewood mother", which is widely used in Guangdong and other places. Some redwoods are called huali, and some are sour when sawed, also called sour branches. Guangdong often calls rosewood rosewood rosewood, which is a historical fact. However, at the seminar on the draft standard of rosewood, more than 20 participants agreed that although rosewood was rarely used in Guangdong in history, it was still appropriate to have a handful of rosewood.
It is not feasible to use common names in business activities. Before there is a more suitable name to replace it, it is more appropriate to use the name mahogany. Some owners and manufacturers of mahogany products are worried that putting rosewood, rosewood, rosewood, rosewood and ebony under the general name of rosewood may reduce its value, especially the value of rosewood. The answer is yes, it will definitely not reduce the value of wood such as rosewood. On the surface, red sandalwood and so on. It's not called rosewood, but it's still called rosewood. In this regard, Article 7 of the Redwood Standard has clearly stipulated: "In business activities, the category of wood, Latin name of tree species, common trade name and place of origin must be indicated."
Second, there are homophones or homophones.
In the past, middle names were only used to identify wood by experience. Although there is some correctness, the understanding of wood is not enough, and it is inevitable to produce synonyms or synonyms of the same kind.
As early as 1942, G. Ecke said in the joinery furniture section of Textual Research on China Huali Furniture: "It seems that there are many different kinds of wood under the same firm." He also said: "It was identified by Dr. H. Hallori as Cassia Siam Elam (author's publishing house: the Latin name of Tielimu is Mesua Ferrea L.), and the scientific name of Tielimu should be Cassia Siam Elam." However, the wood used in the form later was slightly different from that still available in the market, and it was identified as a red bean tree by Chinese experts. " At the same time, he thinks that "Qi is chicken wing wood". Some people call the texture of sandalwood rosewood curly as ox hair rosewood, and the heartwood full of gum as Venus rosewood. Actually, it's all the same kind of wood.
Third, there is no correct Latin name.
No matter what the wood name of tree species is, it must have the correct Latin name (or scientific name, scientific name), and the anatomical structure of wood is the premise. Latin names of animals and plants are restricted by international nomenclature. Latin names use unchanged Latin characters, so they are popular all over the world and are recognized as scientific names by the world; The description and record of wood structural characteristics is the only basis for identifying this tree species. On the contrary, all wood names that are not based on Latin names and wood structure characteristics are passive water or castles in the air.
Limited by the development level of plant taxonomy, especially wood anatomy, it is understandable that Latin names of trees were lacking in the past. According to Tian Jiaqing, foreign scholars had planned to do this research, but in the end it was difficult to obtain materials from classical furniture in Ming and Qing dynasties, and the cost was too high, especially at work ...
Question 3: What is mahogany trading? Mahogany is a general term for high-grade and expensive furniture in China. Mahogany is a tropical plant of Leguminosae and Pterocarya. Originally refers to red hardwood, with a wide variety; After 1980s, people's demand for mahogany is increasing day by day, and the industry needs to be standardized urgently. The state standardizes redwoods according to density and other indicators, and standardizes them into 33 species belonging to eight categories, five genera and two families. Because of its slow growth and hard material, the growth period is more than hundreds of years. Many redwoods originated in southern China were cut down as early as the Ming and Qing Dynasties. Today, most redwoods are produced in Southeast Asia and Africa, and are cultivated and introduced in Guangdong and Yunnan. Of course, the colors of rosewood and wingwood from Huang Huali and Myanmar will not be red. Beautiful wood grain, hard and durable material, used for expensive furniture and handicrafts. 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.
Question 4: What is mahogany? There are many kinds of redwoods, so we can only outline the properties and characteristics of redwoods. Huang Huali, rosewood, rosewood, rosewood, rosewood, rosewood and wingwood are the most common among 33 species of mahogany belonging to 5 genera and 8 categories. Let's talk about the characteristics of these redwoods: 1. Huang Huali. In people's impression, Huang Huali refers to Huang Huali, Hainan, but there is actually Huang Huali, Vietnam, but Huang Huali, Vietnam is not in the national standard of mahogany, but Huang Huali, Vietnam is also of high value. The heartwood of Huang Huali is light yellow to purplish red, with bright colors, clear and beautiful wood grain, and the new cut surface has a strong "Dalbergia odorifera" fragrance. In addition, there are many "grimaces" and "ghost eyes" in Huang Huali. 2. rosewood town. There is only one kind of rosewood in the national standard of mahogany, namely lobular rosewood or sandalwood rosewood. The biggest feature of lobular rosewood is that its color is deep as paint, its brown eyes are thin and dense, and most of its rings are distorted. 3. rosewood, rosewood is characterized by clear texture and bright color, and its wood is divided into old and new. 4. Red sandalwood is divided into red rosewood, black rosewood and white rosewood. Its biggest feature is that it smells sour. 5. Chicken wing wood, named after its texture like chicken wings, is also the biggest feature of chicken wing wood. 6. Ebony heartwood is all black; The wood structure is thin; Very heavy, submerged in water; No wave marks can be seen; No fragrance; Persimmon tree species; Produced in the tropics. 7. The striped ebony porous material is black or chestnut brown with light stripes; Axial parenchyma is mainly concentric layered thin lines with few loose rings; The wood structure is thin; Very heavy, mostly submerged in water; No wave marks can be seen; No fragrance; Persimmon tree species; Produced in the tropics. thank you
Question 5: 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 6: What is mahogany furniture and what kind of wood is mahogany? After long and arduous efforts, experts from the classical school represented by the Palace Museum and the academic school represented by the China Academy of Forestry finally reached a consensus and scientifically defined the tree species belonging to the category of redwood and their technical parameters such as structure and density. Three conditions that mahogany must meet at the same time are clearly defined.
(1) Tree species: five genera, seven categories, five genera: red sandalwood, Dalbergia odorifera, persimmon, cliff bean, ironwood; Seven categories: rosewood, rosewood, rosewood, rosewood, ebony, striped ebony and wingwood.
(2) Structure: The wooden structure is very thin, and the average chord diameter of the conduit is below the specified value. The specific standards are: mahogany: the average chord diameter of the catheter is not more than160μ m; Rosewood, black rosewood, red rosewood and chicken wing wood: the average tangential diameter of the catheter is not more than 200 microns; Ebony and striped ebony: the average tangential diameter of the catheter is not more than150μ m.
(3) Density: When the moisture content of wood is 12%, the air-dried density of all types is above a certain value, specifically: rosewood: the air-dried density is greater than1.00g/cm3; Redwood: air-dried density is equal to or greater than 0.76 g/cm3; Black rosewood, red rosewood, ebony and striped ebony: air-dried density is equal to or greater than 0.85g/cm3；; Chicken wing wood: air-dried density is equal to or greater than 0.85g//cm3.
Because the characterization of mahogany raw materials is a science, it is impossible without standards, and the standard restrictions are too dead, which is not conducive to its development. Therefore, some supplementary explanations are needed:
(1) Ebony: This term is the most popular in Japan and is considered as the best ebony wood product by contemporary Japanese. It is understood that in fact, it is mainly striped ebony, and a small amount is ebony or blackcurrant.
(2) Gall wood: It was called Gall wood in ancient China, because it was a tree tumor caused by disease. It is not surprising that there are local tumors on wood, but a few rare trees will grow bigger tumors, and some will even grow into hollow trees, and all nutrition will be concentrated on tumors. The fibrous mass inside this tumor has changed, forming various beautiful patterns, which we call "eucalyptus". There are many kinds of beeches. Such as birch gall, maple gall, cypress gall, pear gall, etc. Among them, pear gall is the most precious. Some panels of classical mahogany furniture handed down from generation to generation are made of this kind of beech. Galla chinensis has gorgeous wood, is not suitable for deformation, is very rare, and is a very valuable decorative material.
(3) White sour branch: The new national standard has classified it as red sour branch, and it will not be subdivided.
Question 7: What color is mahogany? When it is mahogany products or raw materials, there are brown, purplish red, purplish black and black. The color of white skin is very light, and some of them are close to white, so mahogany is not just red.
Question 8: 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 class 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 9: What is the word mahogany patina Baidu patina? I don't want to get your score for nothing. In fact, in a word, it is the vicissitudes of life left by years on objects.
Question 10: What is it said that mahogany refers to? According to national standards, the range of "redwood" is determined to be 5 genera and 8 categories. The five genera are named after the genera of dendrology, namely Pterocarya, Dalbergia, Elaeagnus and Tilia. Eight categories of wood are named after their trade names, namely rosewood, rosewood, rosewood, rosewood, rosewood, ebony, ebony, striped ebony and wingwood.
