The difference between rosewood and huanghuali

Caohuali old material does not agree with the view that Asian pear wood is called 'Caohuali' in the market. In order to see and listen to the sound, the following will try to use 'rosewood' or specific professional titles instead of 'caohuali'. Distinguishing between 'grass' and 'yellow' of rosewood Among the furniture of Ming and Qing Dynasties, there are a large number of rosewood furniture surviving. Even some palace furniture in the Forbidden City are also made of rosewood. When I visited the Forbidden City, I saw it with my own eyes. However, both in name and appearance, rosewood and huanghuali are somewhat similar, which is difficult to distinguish at first glance. The industry’s identification of some old furniture materials is often controversial because of the similar appearance of rosewood and huanghuali. Especially for some consumers who do not know much about wood, it is very difficult to make accurate judgments. Rosewood, a tree species of the legume Pterocarpus spp. There are about 70 tree species in the genus Pterocarpus. In addition to the Pterocarpus sylvestris classified as Pterocarpus, another 7 species are rosewood. According to the national standard of 'RedwoodThere are a few unscrupulous merchants on the market that use methods such as dyeing, distressing, and applying hardener on the surface to pretend to be huanghuali or rosewood in the mahogany standard for sale in the flea market and furniture market. The common characteristics of this type of wood are generally lighter specific gravity, loose material, longer brown eyes, and mainly red or light red in color, generally 80cm-160cm large diameter wood. Rosewood was not distinguished from Huanghuali during the Ming and Qing Dynasties. The imported wood of the genus Pterocarpus rosewood and the Dalbergia odorifera produced in Hainan Island are both called Huali. They are both in the same family and different genera. Different species are completely different two kinds of wood. Extended reading: The name evolution of Hainan Huanghuali. The wood of Huanghuali is extremely stable. It is not easy to be deformed, cracked or tortuous regardless of cold or heat. It has a certain degree of toughness and is suitable for making all kinds of furniture; rosewood is bright in color, delicate in texture and clear in texture; The pear wood is more coarse, the brown eyes are too large, and the color is yellowish, dry and dull. To identify whether an old piece of furniture is rosewood or huanghuali, the following points can be used: the huanghuali pattern is delicate and vivid, clearly distinguishable, and not chaotic. Black line patterns are mostly, and dark brown and red line patterns are occasionally seen, with 'ghost faces'. Good huanghuali has good oil properties and is not easy to deform when made into furniture. Compared with huanghuali, the pattern of rosewood has less changes. Another very important point is that if the shape and texture of an old piece of furniture show the characteristics of the late Qing Dynasty and the Republic of China, it is more likely that this piece of furniture is rosewood, and it must be carefully screened. Among the seven rosewoods of the genus Pterocarpus in the national standard of 'Redwoodcm3, the color of the heartwood ranges from reddish brown to purple reddish brown, often with black stripes. Another relatively good rosewood is bird's foot red sandalwood, which is produced in tropical areas of the Indo-China Peninsula, mainly Laos and Thailand. Often with dark stripes. Here, we will give a detailed description of Pterocarpus macrocarpa and Indian Pterocarpus which have a long history of use in our country. Big fruit red sandalwood, commonly known as Burmese rosewood, was the main raw material of rosewood in the Qing Dynasty. Many classic furniture handed down from the world are made of large fruit red sandalwood, many of which are exquisite. Pterocarpus is mainly produced in Myanmar, Thailand and Laos. Its wood grain is clear, the heartwood is orange, brick red or purple, often with dark stripes; scratches are visible to obvious; after the wood chips are soaked in water, the water is pale yellowish brown with little or no fluorescence. The wood fiber wall is thick, and the structure is fine and uniform. The material is hard and heavy, and the air-dry density is 0.80-0.86g/cm3. Because Daguo Pterocarpus has a long and mellow aroma, people also bestow it with a reputation-Fragrant Pear. Further reading: How to identify Pterocarpus roseus Indian Pterocarpus is also called rosewood, which is also one of the traditional furniture materials in my country. Large deciduous tree, 20-25 meters high, dark brown bark, straight and sliding trunk. Leaves alternate, odd-pinnately compound leaves, drooping. Produced in South Asia, Southeast Asia, the Solomon Islands and Papua New Guinea, it is also distributed in a small amount in my country's Guangdong, Yunnan and other places. Indian red sandalwood has obvious growth rings, the heartwood is reddish brown, dark reddish brown or golden yellow, often with dark and light stripes; after the wood chips are soaked in water, the water is dark yellowish brown with fluorescence. The air-dry density of Indian red sandalwood is 0.53-0.94g/cm3. Therefore, some scholars believe that although this wood is among the mahogany listed in the national standard of 'Redwood.76g/cm3, and classify it as Yahuali. Regarding this point, the author believes that it can be viewed dialectically. Those Indian red sandalwood whose air-drying density meets the requirements of the national standard can be regarded as redwood, while those that do not meet the standard are non-redwood. This is also applicable to the judgment of whether red sandalwood plantations are redwoods. . Regarding Indian red sandalwood, there are some very interesting points: in April, the flowers are full of trees and the fragrance is permeated, but the flowering period is short, known as the one-day flower; because the roots are shallow, the Indian red sandalwood cannot withstand the invasion of wind and rain. , But they are extremely fertile, and can regenerate by putting the broken branches back into the soil.
