Whether it is Hainan huanghuali or Vietnamese huanghuali, they are very rare natural resources and are extremely precious. It is precisely because of the inconsistency between the characteristics of the wood itself and the inherent preferences of the people that the difference in their value judgment provides a good opportunity for the bad manufacturers to counterfeit. The methods of fraud include the following: 1. Distress: Distressing itself cannot be said to be fraudulent, but if the old furniture is used to pretend to be an antique of the Ming Dynasty and the Qing Dynasty, it is a fake. This is one of them. It is the second of the furniture made by Vietnamese huanghuali to pretend to be Hainan huanghuali furniture. will It is similar to the color and texture of Hainan huanghuali, such as yellow rosewood or rosewood, which is made of furniture and then worn out. This is the third. The old method is usually burned with sulfuric acid and passed through the lime pool. It also uses hydrogen peroxide and other Chinese herbal medicines and chemicals to make the wood discolored and old, and some use colored wax to change the color of the wood. It is not surprising that some old-fashioned furniture experts or collectors of the Ming and Qing Dynasties can often go out of their way. 2. Other methods of fraud: A. The conspicuous place uses Hainan huanghuali, and other unobvious places use Vietnamese huanghuali. For example, rounded cabinets, Hainan huanghuali on the front, Vietnamese huanghuali on the side, back plate or partition, and rear column, labeled Hainan huanghuali. B. The overall furniture is Vietnamese huanghuali, and the label is labeled “Hainan Huanghua Pear†or “Huanghua Pearâ€, and some are labeled as “Scented Woodâ€. In the "Redwood" standard, Hainan huanghuali, that is, fragrant yellow sandalwood, is classified into fragrant wood. What is "fragrant wood"? Guangdong people call the scented rosewood as "fragrant wood". There is no species of Vietnamese huanghuali in the "Redwood" standard, but the wood testing agency often tests the Vietnamese huanghua pear as "fragrant wood" and belongs to the genus Dalbergia. As for why the tree species have no results. That is to say, using Vietnamese huanghuali as the furniture label "fragrant wood" or mixed with "huanghua pear", it is difficult for collectors to win the lawsuit. C. Use yellow rosewood, rosewood and other hardwoods to impersonate huanghuali directly, but the price is very low. D. At present, there is a more horrible method of fraud in the Beijing market in the past 2-3 years, but it is difficult for collectors to detect it, that is, using the method of “skinningâ€, the surface is coated with 0.2 mm thick Hainan huanghuali in acid. Branches or other woods with a specific gravity equivalent to huanghuali, the color and texture of the front and back sides are completely consistent. The price of this furniture is almost the same as that of all Hainan huanghuali furniture. The northern part of the country is dry in winter and the air humidity is small, which makes it easy to crack such furniture in the south. If cracking occurs, the gap should be observed with a magnifying glass. If the interior of the wood is inconsistent with the color of the furniture surface, experts or professional testing agencies should be inspected.
