There are many wood classifications of mahogany furniture, Hainan huanghuali, Vietnamese huanghuali, iron peas and red rosewood. Professionals have put forward some suggestions on how to distinguish these woods.
Yang Hongbin is the person in charge of a private enterprise in Yunnan. He introduced that there are many varieties of redwood, which are produced in Southeast Asian countries, India, and Africa, but the price difference of different woods in the production area is also very large. Some merchants do not indicate the origin of the wood or intentionally confused, and consumers are often difficult to distinguish.
Such as the Vietnamese huanghuali posing as Hainan huanghuali - both are very fragrant after sawing, after polishing, the patterns are colorful, the color is mostly golden yellow, the wooden pores are small, the hand feels smooth, polished after the mirror as a mirror, there are many Nodules form a grimace pattern. However, the texture of Hainan huanghuali is clear and identifiable, and the thickness is consistent and lively. The texture of Vietnamese huanghuali is slightly thicker, and most of the turbidity is unclear, wide and narrow, intermittent, and some textures will change dramatically. Vietnamese huanghuali does not have Hainan huanghuali scent, the color is lighter, and the ghost face is slightly worse, but its tree material is thicker than Hainan huanghuali.
Another example is the use of African ebony, Kaliman Tan to mix striped ebony, because they also have black stripes. Striped ebony is black with many stripes and white stripes, while African ebony and Kalimantan white stripes are obvious. The ebony wood has a fine structure and a large proportion. It sinks in water and has no aroma.
In addition, African chicken wing wood is often used in the market to impersonate Burmese chicken wing wood, because the price is only a fraction of the latter. When the identification is one, the finish is smooth, the Burmese chicken wing wood is smooth and delicate, the African chicken wing wood is rough; the second is the specific gravity, the density of Burmese chicken wing wood is large; the third is to look at the style, the Burmese chicken wing wood is small, can only be used as chairs, several types, etc. Small pieces of furniture, while African chicken wing wood raw materials are large in diameter, and can be used as large cabinets, Arhat beds and other large pieces of furniture.
