The selection of new mahogany refers to the scientific name of Dalbergia odorifera (Huang Huali, Hainan): Dalbergia odorifera color: reddish brown, often mixed with black stripe smell: the new cut surface has a strong spicy aroma, but it is slightly fragrant for a long time. Dalbergia odorifera, the scientific name of Huang Huali, Vietnam and Huang Huali, Hainan, the old rosewood, was Dalbergia odorifera, and this name didn't exist until 1963. Before that, two kinds of wood were called Huang Huali, because of their similarity. For these two kinds of wood, one is called rosewood, also called furan pear, and the other is called rosewood, also called avocado. At present, the academic circles call the former Dalbergia hainanensis and the latter Dalbergia odorifera, commonly known as Hainan Huang Huali. The traditional name Huang Huali was renamed Dalbergia odorifera, which is known as the only fragrant wood and the only renamed wood in the national standard of mahogany. Huang Huali has fine structure and strong durability, and some of them have beautiful grimace patterns. More importantly, it is linked with the traditional feelings of China people. It is a kind of natural and beautiful wood, with outstanding temperament and incomparable nobility. This material is rare in the furniture market because of excessive logging. After Huang Huali, another tree was found in Viet Nam. This kind of tree is very similar to Huang Huali, with similar fragrance and grimace patterns. After testing, it belongs to Dalbergia like Huang Huali. The person who found this tree thought it was Huang Huali, Hainan, produced in Vietnam, and called it Huang Huali, Vietnam. In fact, there is a big difference between the two. Red rosewood and Huang Huali, Hainan belong to Dalbergia odorifera. The appearance of old rosewood and Huang Huali, Hainan are similar, but the smell is obviously different. During the Ming and Qing Dynasties, no one used furry pears as furniture, and the two kinds of wood were also well distinguished: furry pears were not too oily and yellow in color; Avocados, as the name suggests, are oily and red in color. Compared with Hainan Huanghua, Huang Huali is yellow and light, and its stability is different. Huang Huali has clear texture and different shades. Most of the Vietnamese Huang Huali is muddy, some of which have traces similar to flooding, and the texture changes greatly. Yang Jiaju: The reason why Huang Huali has such a high status in China at present is based on the experience of generations of furniture makers and users, and it is the result of historical verification. In terms of wood properties, it is very stable with sandalwood rosewood. Crucially, Huang Huali is an endangered species in China, almost extinct. Although there are replanted woodlands in Hainan, the number is small, and it will take at least 300 years for this forest to mature. Vietnamese Huang Huali does not belong to the category of national standard of redwood. Sandalwood scientific name: Sandalwood Sandalwood material color: red-purple, long-term exposure to the air will turn black-purple, with a slight fluorescent smell: Sandalwood tastes like wood: black rosewood, red rosewood. There are many kinds of mahogany furniture on the market. Better ones, such as hedgehog rosewood and big fruit rosewood, belong to rosewood, and similar ones, such as African rosewood, are not in the category of mahogany at all. There is only one kind of real rosewood, that is sandalwood rosewood, which is also called "lobular rosewood" by merchants. Sandalwood rosewood will have a little purple even after oxidation, which is calm and restrained. Some are covered with gold stars, and some show curved cow hair patterns. The furniture made is very heavy and can smell the obvious sandalwood smell. Old rosewood furniture is very similar to rosewood. It is also rosewood, and its quality is very different. Yang Jiaju: When rosewood furniture is sold in the market, it will be divided into Venus rosewood and ox hair rosewood. Venus and cow hair patterns are attractive appearances of rosewood, but they are not unique features of rosewood. Heartwood vessels contain reflective deposits, which are Venus rosewood. In fact, whether you can see "Venus" is related to the time when heartwood was formed and the position of woodworking saw. As for the cow hair pattern, it is the external conditions such as wind direction that affect the growth of tree cells during the growth of trees, forming staggered and curved textures, which are also commonly known as cow hair patterns, and these are only the external characteristics of individual rosewood. Some good rosewood and sandalwood rosewood are almost identical, and experts sometimes make mistakes. For example, I have seen a weighing scale, which many experts think is made of rosewood. After being tested in the laboratory, it was found that it was a kind of Dalbergia odorifera. This kind of situation that cannot be recognized by the naked eye is not very high. In general, the difference between rosewood and rosewood is obvious. In color, rosewood is deep purple, rosewood is deep red, and the stripes of rosewood are more obvious than rosewood. Lushi black rosewood in black rosewood is also called big leaf rosewood because it is similar to sandalwood rosewood. In fact, rosewood and rosewood are two kinds of wood. It is also red sandalwood, and its value and quality are different. It is said in the market that rosewood can be divided into artificial forest and wild forest, with great differences in price and quality. In fact, the planting of rosewood can be divided into forest and mountain forest. The ground forest is artificial, and because the nutrients and sunshine of the flat soil are not as good as those of the mountain forest, the wood produced by the mountain forest generally grows slowly, but the quality is good. Wang Xiulin: The fiber structure of rosewood is like a person's curly flower head. Long and shoulder-length, not easy to crack and deform, relatively stable. Cao Huali has no such structure. Although it looks like rosewood on the surface, it is easy to crack. When the appearance is very similar, the main way to distinguish rosewood from rosewood is to smell it. You can use sandpaper to grind off a small piece of paint on the back of furniture, or you can scrape off some sawdust with a knife and rub it hard with your hands to get heat, which can enhance the smell of wood. Red sandalwood tastes like sandalwood, and the sour branches are obviously sour. Because rosewood contains a lot of pterostilbene, if you rub it with white paper, you will see red powder. Scientific name of rosewood: black rosewood, red rosewood (distinguished by wood color) Black rosewood color: chestnut brown rosewood color: reddish brown to purple smell: sour rosewood furniture is also a wood with large price difference in the market. The label also says rosewood, but the price of furniture with the same shape is quite different. In addition to the different processes of furniture workmanship and wood treatment, the quality of rosewood itself is also very different. Some merchants decide the quality according to the origin of rosewood. In fact, it is not that the so-called Lao rosewood is produced in Laos, but Myanmar rosewood is produced in Myanmar. The rosewood furniture with good quality and deep color, after oxidation and patina, is very similar to sandalwood rosewood, but the texture is clear, often with dark brown stripes, but the mane is larger than rosewood. Poor quality rosewood has a rough texture and uneven feel. There is a kind of red tiedou wood, commonly known as African rosewood, commonly known as rosewood, which looks similar to rosewood. Compared with red sandalwood, the texture and mane of this kind of red sandalwood are not obvious. Yang Jiaju: There are many kinds of acid tree species, and there are differences in tree species and materials. Since ancient times, there has been a distinction between Lao rosewood and Myanmar rosewood. In fact, there is no administrative division of plants, but the first batch of imported high-quality red rosewood came from Laos. Therefore, the later high-quality red rosewood is called Laos red rosewood. Tree species are related to the soil climate, and the whole tree is different in each section, and the wood on the sunny slope is also different. As for African rosewood in the market, I think the quality of wood named after Africa is not good-for the growth of mahogany, the climate conditions and temperature environment in Southeast Asia are better than those in Africa. Scientific name of rosewood: rosewood wood color: generally reddish brown, usually with obvious fluorescent smell: pungent and similar wood: rosewood and other kinds of rosewood, such as Caohuali and Yehuali, have heartwood ranging from light red to dark brick red, and the new section has aroma. There are seven kinds of national standard "Redwood", which are usually called purple pears. In addition to purple pear, we can often see Asian pear and grass pear, which are far from rosewood pear and somewhat similar in appearance, so furniture salesmen will add the words "Asia", "grass" or "new". For the selection of rosewood, the general view is: look at the texture, look good or not, like it or not; The second is the smell, which smells good and smells bad; Triple, too light is not good; Fourth, look at the wood, the texture with large sex is distorted, and the texture with small sex is straight. Yang Jiaju: Purple pears are cheap and mahogany is good. The so-called Wu Mei, that is, wood is very heavy, not easy to crack and deform, better than acid branches; Cheap because tree resources is rich, with large tree diameter and high timber output, so the price is low. Common African rosewood belongs to grass pear. Compared with rosewood, it is loose in texture, light in weight and, most importantly, seriously discolored. If a gray African rosewood is not painted, it will soon turn almost gray in the air. Wang Xiulin: Purple pears are very suitable for making furniture, and they are easy to identify. They turn blue when they meet water. I had an experience in the past, that is, whenever it rained, the water flowing out of the warehouse where rosewood was piled was blue. This is because rosewood contains tungsten, so it turns blue when it meets water.
