Dalbergia sinensis (scientific name: Dalbergia odorifera), endangered species, specialties of Hainan, and evergreen trees of the subfamily Vulgaris. Its wood is known as "Pear," commonly known as "buckywood," and "Compendium of Materia Medica," called Dangxiang, its sawdust water can lower blood pressure, blood lipids, and its wood hard, beautiful texture, is the production of classical hardwood furniture Superior materials. Although the Dalbergia is easy to survive, it is extremely difficult to produce. The true growing needs a period of hundreds of thousands of years. Therefore, as early as the late Ming and early Qing Dynasty, Hainan Huanghuali wood species were on the verge of extinction. Huanghua pear wood and rosewood, chicken wing wood, iron wood and called the four famous ancient Chinese wood.

Wood structural features

Bulk material to semi-ring material. The growth wheel is quite obvious. Heartwood new cut purple brown or dark red, often with black stripes. The tube pores are visible to the naked eye with a chord diameter of up to 208 μm, an average of 114 μm; the number is very small to slightly less, 2 to 12 per mm2. Axial parenchyma can be seen under the naked eye. The main part is a sacral band (mostly 1 to several cells wide) and polywings. Wood fiber wall thickness. Wood ray is obvious under the magnifying glass; wave marks can be seen; ray organizations are homomorphously single-column (rarely) and multi-column (2 to 3 columns, 4 columns occasionally). The new section is pungent and full of gas, but it is slightly fragrant for a long time; the structure is fine; the texture is oblique or staggered; the air-dry density is 0.82~O. 94 g/cm3.

Scented Dalbergia Classified

Dalbergia is also known as huanghuali. Huanghuali is a literary name and there is no tree called "Pear Tree" from ancient times to the present. It has a new scientific name called "Dingxiang Dalbergia." As for the varieties of this wood, there is no accurate statement. Observed with the naked eye, there are roughly two types of huanghuali wood. One kind of color is light, brownish yellow; one kind of color depth is brownish red. The differences between the two types of yellow pear wood are obvious, and their characteristics are different.

Light yellow pears generally have a strong luster, even if wax is lost for a long time, and after a little finishing, faint light will flash. The weight is slightly lighter, the texture is clear and smooth, not warm. This kind of furniture made of light-colored pears has been found mostly in the north, especially in the city. It is more common in light-colored yellow pears. Dark-colored pears are highly oily by visual inspection, and therefore have less luster than light-colored pears. In comparison, the dark-yellow pears are heavier in weight, and their texture is not as clear as light-colored ones. The origin of this kind of yellow pear furniture is often more in the south than in the north.

Difficulties in the identification of wood in Huanghua pear furniture often stem from three aspects. First, it is not related to mahogany. The dark yellow pears, if used for a long time, are not in good condition. At first glance they look very much like mahogany. In fact, judging from the essence, the wood of Huanghuali is small, so the deformation rate is also small, light and gentle. Grasp this point, other problems can be resolved; the second is not separated from the grass pear. The occurrence of Caohua pear was due to the severed timber of Huanghua pear, which was added to the market in the late Qing Dynasty to Shanghai as a supplement, and was the lowest in hardwood. Its woodiness is sparse, the brown eyes are too large, and the color is yellow and dull. Third, it is not separated from the new yellow rosewood. The weight of the new material is also heavier than that of the old wood. The wood grain contains too many black lines and is stiff, so many woods The pattern is too beautiful and eye-catching, but new yellow rosewood.
