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 tables and chairs are inlaid with Yunnan marble, marble, Luodian shell and other decorative accessories, which can better reflect the traditional style of mahogany furniture. Some people buy mahogany furniture, perhaps not only considering Chinese and western styles, but also pursuing the regional style of mahogany furniture. For example, Beijing School pays attention to craftsmanship and Cantonese style pays attention to sturdiness, while Su School and Shanghai School are regarded as authentic representatives of pure Chinese furniture, and they need to be carefully identified when purchasing. (4) Quality requirements. When choosing furniture, we should pay attention to the rationality of furniture structure, the scientific nature of tenon and mortise, the advanced technology and the applicability of function. For example, mahogany furniture generally adopts tenon-mortise structure, so pay attention to it when purchasing. The identification of mahogany furniture mainly depends on its wooden structure and weight. The identification method is as follows: 1 See if the wood structure has the characteristics of the above mahogany, that is, whether the wood itself has natural colors such as red, yellow and wine red; Whether the wood grain is simple and beautiful, elegant and fresh, and whether it is still clearly visible after painting. After the fake mahogany furniture is painted, generally speaking, the color is thick, often white, and no lines can be seen. Second, look at the weight. Real mahogany furniture is strong and firm, and its texture is particularly compact, which is heavier than ordinary oak. Fake mahogany furniture of the same shape and size is obviously lighter than the real one. Third, distinguish between mahogany furniture and mahogany towel furniture. Although some products are made of mahogany, a closer inspection reveals that their products are made by chopping mahogany into thin slices and sticking them on other wood surfaces in disguised form, and are not really pure mahogany furniture. ? 4. When buying mahogany furniture, it is best to go to a regular furniture store with good consumer reputation and high credit rating, carefully check whether the material and paint marked on the product label are consistent with the finished product, and ask carefully to avoid unnecessary losses caused by mistaken purchase. With the initiation of people's concept of being close to nature, the fashion of returning to nature and the approach of well-off families, mahogany furniture in the furniture market is increasingly favored by consumers for its high-grade quality. How to identify mahogany, choose mahogany furniture, reduce blindness and avoid being deceived by real objects is particularly important. The so-called mahogany furniture mainly refers to furniture made of rosewood, rosewood, ebony, beech, rosewood and chicken wing wood. Because mahogany furniture is very expensive, some manufacturers are greedy and often pretend to be mahogany furniture with fake mahogany furniture to make huge profits. Therefore, fake mahogany furniture occupies a considerable proportion in the market. The colors of these fake mahogany furniture are basically red or reddish brown; The density is also relatively large, close to mahogany; The wood grain is similar to mahogany. For example, furniture made of Quelamu in Papua New Guinea (also known as pineapple in Papua New Guinea) and Gamba in Indonesia is really difficult to distinguish from mahogany furniture after painting. Although the appearance of true and false mahogany furniture is similar, the quality is still very different. Even the precious wood pineapple lattice (fake mahogany) is no exception. This is because the growth of mahogany is extremely slow, the material is extremely delicate and uniform, and the material is stable, while the growth of fake mahogany is fast and the material is thick; Mahogany wood itself has the function of preventing insects and berries, which fake mahogany does not have; Although the density of fake mahogany is also high, its hardness is far less than that of mahogany, so its life span is only ten or twenty years, far less than that of mahogany for hundreds of years, and it is impossible to survive. Therefore, when choosing mahogany furniture, we must polish our eyes and distinguish between authenticity and falsehood, so as not to buy fakes. Pay attention to the following points when distinguishing between true and false: 1. Identification from the name: (1) Red sandalwood grows for a long time, and its tree species are precious, so logging is prohibited in many countries. Therefore, mahogany furniture is very rare in the domestic market, so we should pay special attention to mahogany furniture marked with mahogany. In addition, (2) the characteristics of heartwood such as ebony and sour branches are obvious, so there are few fakes. (3) There are many fakes in the mahogany market. One of the more common fake redwoods is pineapple lattice, which is a kind of dark precious hardwood, although it does not belong to the redwood family. In addition, there are some fake mahogany imported from Southeast Asia, Oceania, South America and Africa, such as Kundian, Gamba (Burmese rosewood), Burmese red, Quelamu, red willow eucalyptus, Mongris, Vietnamese rosewood and Brazilian rosewood. 2. Judging from the price appraisal, the price of fake mahogany is relatively cheap, generally ranging from 0/500-4,500 yuan per cubic meter. Mahogany furniture is expensive, among which rosewood is the highest and rosewood is the lowest. If you buy a five-piece sofa (one couch, two single person sofa's, one big and one small coffee table), there may be hundreds of thousands of red sandalwood, but there are ten or twenty thousand red sandalwood. The price per cubic meter of wood is roughly as follows: rosewood 9-140,000, ebony 36-40,000, wolfberry 35-40,000, acid branch 24-24,000, rosewood 0.8-120,000. 3. Identification from wood grain: At present, mahogany accounts for about 50%, rosewood accounts for 40%, ebony accounts for 65,438+00%, and rosewood is extremely rare. So it is enough to master the textures of these kinds of wood. Rosewood: It is the best in mahogany. Its wood is hard, the color is purple-black, it feels heavy, the annual rings are textile-like, the texture is delicate, and there are irregular crab claw patterns. Rosewood is divided into old rosewood and new rosewood. Old rosewood is purple-black, and it does not fade when immersed in water. The new rosewood is reddish brown, deep red or deep purple, and will fade when soaked in water. Ebony is the easiest to identify. The deepest color is jet, which has a black metallic luster and a sense of bone China; The texture is very fine and even, but irregular, or wavy with light black stripes. Ebony has a higher specific gravity than water and can sink into water. Gall wood: it is the wood after the tree gall. The texture curve of gallnut is patchy and beautiful. It is the best decorative material, mostly used for surface inlay in furniture. For example, there is a folk saying called "Red Table and Bold Wood Face". This kind of wood is extremely precious and rare. Acid rosewood: commonly known as old mahogany. Wood is hard and heavy, durable, can sink into water, and has fine structure, lemon red, deep purple and purple-black stripes, dark red or reddish brown in color and luster. Wood is uneven in color, with dark brown or black stripes, and the texture is inclined and staggered. When processed, it gives off a pungent smell with sour taste. Rosewood, light in color, yellowish red or brownish red, some with stripes, luster, uniform color, interwoven textures, beautiful patterns, some with bright spots and special rose fragrance. Rosewood is similar to rosewood in structure. Its wood is hard, yellow or purple in color, rainy in texture, soft in color and light in weight, and it can float in water. At present, mahogany furniture on the market is mostly rosewood. Chicken wing wood: the wood is hard, with three colors: black, white and purple, forming chicken wings with feathers and bright colors. However, because wood contains impurities such as fine gravel, it is difficult to process and is suitable for decorative corner materials. Therefore, it is difficult to see complete sets of chicken wing furniture in the market. Real mahogany furniture itself has different natural reds such as purple, yellow, red and crimson, and the wood grain is simple and beautiful, elegant and fresh. After making furniture, although there are colors, the wood grain is clearly discernible, while imitations are generally painted with thicker colors, often white, and have no texture. Real mahogany furniture is strong, delicate and heavier than ordinary wood. Compared with fake mahogany furniture with the same shape and size, the weight is obviously different. Materials The materials of antique furniture can be divided into "cork" and "hardwood". Hardwood is more valuable because it has higher density, better texture and heavier quality. Rosewood and rosewood are very expensive. Corks include nanmu, beech, elm, cypress, beech, Chinese fir, white wood and camphor wood. The price of antique furniture is mainly judged by "age, material, rarity, completeness and appearance". Old rosewood and mahogany furniture can be sold at high prices. People who are keen on antique furniture may wish to refer to the knowledge of mahogany furniture and start with the selection of cork furniture. The method of processing and finishing from a small angle is a necessary process to revitalize antique furniture, and the accuracy of processing should also be paid attention to. The arrangement of the drawer bottom plate, whether the grinding is meticulous, whether the paint is uniform, whether the wood grain is complete, whether the linen on the cabinet back plate is in good condition, etc. , are places where the accuracy of antique furniture can be judged. Various kinds of redwoods, due to different tree species, different physical and chemical properties, more or less output, and different prices, cause differences in furniture production. Mahogany furniture can be roughly divided into three categories: Mahogany furniture: kitchen, cabinets, tables and other furniture. Except for the top and bottom plates, all other parts are mahogany. Beds, sofas and other furniture are made of mahogany except that the skeleton is replaced with high-quality hardwood. Chairs, stools and coffee tables are all made of mahogany. Mahogany veneered furniture: Except the door panel, table top, stool surface, sofa surface, side surface and bedside surface are made of solid wood, other exposed frames, stalls, footstones, decorative lines, top cover and footboard are made of mahogany. Non-exposed wood parts can be replaced by high-quality wood. Mahogany veneered furniture: With the progress of science and technology, in order to save mahogany materials, mahogany veneered furniture appeared. This kind of mahogany furniture is a frame made of mahogany, and the surface and exposed parts are covered with mahogany. However, this kind of mahogany veneer furniture is not much at present, because there are fewer and fewer mahogany materials, which is the future development direction, but the production technology should keep up. What points should be paid attention to in mahogany furniture maintenance? 1. Redwood is solid wood furniture, which is prone to quality problems within one year after leaving the factory and needs maintenance. It is best to use a humidifier in winter; Use air conditioning in summer to keep the indoor humidity between 25~35%. 2. Avoid long-term exposure of furniture in the sun, and don't put furniture directly in high-temperature places such as heaters and fireplaces. 3. Dust is an abrasive particle. When wiping the dust, gently wipe it back and forth along the wood grain with a soft cotton cloth. If you wipe the paint surface with a hard dry cloth, it will cause scratches and lose luster. 4. You can wax the furniture once every six months or once a year, which helps to protect the furniture. 5. If you move furniture, you should lift it, not drag it, so as not to loosen the overall structure of the furniture.
