Mahogany furniture refers to furniture made of rosewood and other redwood, which is the collective name for rare and precious hardwood furniture since the Ming and Qing Dynasties. The quality of mahogany furniture is very popular among consumers, but the expensive price has also made many people discouraged. There are some unscrupulous merchants in the market who use some fake methods to fool consumers. If you are planning to buy mahogany furniture, you must understand these tactics.
Technique 1: stealing the column
It is difficult for people who are not experts to visually see the difference in wood from the naked eye. This is also a common way of fraud for some bad businesses. They mix wood with similar colors and textures to deceive consumers.
• Rosewood furniture
It is often mixed with old mahogany and deep red lacquer wood in places that are not obvious. The L. black rosewood of the black saplings of the genus Dalbergia, which is produced in the Madagascar Islands, pretends to be the sandalwood of India, namely sandalwood rosewood.
• Yellow pear
The so-called "Vietnamese huanghuali" produced in Vietnam, Laos, is the huanghua pear that is produced in Hainan Island. It is a rosewood that is produced in Laos or Laos and borders Myanmar. Pretending to be a huanghuali; mixing "Vietnamese huanghuali", rosewood and Hainan huanghuali, and even more daring, the yellowish rosewood is directly labeled as "huanghuali", the buyer asks to say "Vietnamese huanghuali" "The actual Vietnamese huanghua pear is not."
• Rosewood
Avocado or rosewood having a dry density of not more than 0.76 g/cm3 produced in Africa or South America.
Technique 2: Utilization of sapwood and heartwood
The color of the wood is naturally formed, especially the hardwood is rarely consistent. In fact, this is one of the natural properties of wood. The wood is composed of sapwood and heartwood, generally near the bark, lighter in color, and moisture. More, called sapwood. In the surrounding part, the color is darker and the water is less, called the heartwood.
According to the national standard of mahogany (GB/T18107-2000), "redwood" refers specifically to the heartwood portion of wood, and the sapwood portion does not belong to mahogany.
Why do you want to make such a rule? Because sapwood is the part of trees used to transport sap, transfer and store nutrients, it is not like "heartwood", it is "live wood", so it is easy to attract insects. Density and other indicators are not as good as heartwood. If it is also regarded as "redwood", it will greatly reduce the quality of mahogany. For example, the sapwood of Hainan huanghuali is light grayish white or light yellow, and has no fragrance. It is the most harmful pest of termites. It is the natural food of termites, and its heartwood is fragrant and fragrant, and the scented oil is enriched. Termites do not like it. And the color of the heartwood is obviously different, so it is not possible to mix the two.
In order to increase the yield and reduce the cost, some manufacturers use sapwood (also known as "white label") and heartwood to dye the sapwood with a heart color with a chemical dye. Red sandalwood, old redwood and rosewood all have this phenomenon. This cost can be reduced a lot, and the market price is also very competitive.
For mahogany furniture, whether there is sapwood, there are always two kinds of sounds, one thinks that sapwood can not be used. The "Redwood" national standard clearly states that "redwood refers to the heartwood part of wood, and the use of sapwood will reduce the quality of the product; another It is believed that sapwood can be used, and even sapwood should be used as much as possible, and the scarce resources such as mahogany should be used to the fullest extent.
In fact, both of these statements have certain limitations. Accurately, sapwood can be used on mahogany furniture, but it is used conditionally, based on the industry standard, the standard for dark and expensive hardwood furniture (QB/T2385-2008).
The standard said: "The material of the front side of the product should be free of sapwood; the sapwood area of ​​the surface of other parts should not exceed 1/10 of the surface area of ​​the part (the sapwood with a width less than 8mm is not counted)." Wood should be insecticidal and repaired, and wood that is still eroded by live insects should not be used." Because the "dark expensive hardwood" listed in the "Dark and expensive hardwood furniture" standard includes 33 kinds of wood in the "Redwood" national standard, mahogany furniture can also be called dark precious hardwood furniture, so mahogany furniture can be used. Sapwood, but must be strictly limited to the standard range.
The National Furniture and Indoor Environmental Quality Supervision and Inspection Center's opinion is: If there is a consumer to bring the test, we will ask the person to detect what. If you come to the person to test the furniture material, then the "Redwood" standard is applied; if the quality of the furniture is tested, then the "Dark and expensive hardwood furniture" standard is applied to see what the consumer demands.
Therefore, the same mahogany furniture, only the use of heartwood, and the doping of sapwood, there is a gap in the quality, especially the manufacturers of some technology, if the sapwood used is not handled well, still live When the insects are inside, it may cause the furniture to become infected.
Technique 3: Cut corners
1 reduce the original size of the furniture
The overall size of the original is reduced, lengthened and shortened, curved straight, thick and thin. For example, the large side of the seat of the circle chair is generally 3.5cm, but there are many ring chairs on the market with only 1.5cm on the big side, or only 2cm, and good is 2.5~2.8cm. This can greatly save wood, reduce costs and increase market competitiveness. General collectors are not paying much attention to such places.
2 stitching and skinning
The front legs of the circle chair and the back and forth must be "one wood", that is, a piece of wood runs from top to bottom. Is it "one wood to do", it must be seen whether the texture above and below can be linked, the color is consistent. "One wood is even" consumes a large amount of material, and when it is connected by two pieces, it can be used with small materials, and the cost is greatly reduced, but it also affects the overall taste and viewing effect.

Nowadays, due to the soaring prices of huanghuali and red sandalwood, a few enterprises have smashed huanghuali and red sandalwood into veneers and attached them to the surface of furniture. The thickness of the veneer is about 0.2mm, which is almost transparent. There are two kinds of stickers: First, the surface of the veneer and the substrate are always, but the material of the substrate is poor, and the defects are different or the length is different. Second, the surface veneer is completely inconsistent with the substrate, such as the surface of the yellow pear. Plate, the substrate may be grass pear or other cheaper wood.
3 simplified or not at all
æ¦«å¯ is the soul of mahogany furniture, the essence of traditional Chinese wood craftsmanship. Scientific considerations of the tightness of the crucible and the rationality of the mechanical balance, the use of clever ideas, the use of compact and accurate æ¦«å¯ structure to closely combine the various components of the furniture together, more natural and durable.
However, some manufacturers use machine-operated water, and the furniture link is seen from the outer surface. In fact, the machine is eye-catching and then chemically smeared. There is no traditional, tight-fitting æ¦«å¯ structure inside. This also greatly increases production efficiency.
4 copper live
Hardwood furniture for investment and collection, copper work is also very particular about, must use the best color, feel good brass or high quality white copper, good white copper is generally rare. Nowadays, the copper skin on the market is often used, and it is attached to the furniture after cutting, and the degree of biting is very poor. Copper is the finishing touch, and if the accessories are not appropriate, it has a great relationship to the overall visual effect of the furniture.
5 wax live
Hardwood furniture generally wax, wax or shake wax, especially red sandalwood, huanghuali, different materials of furniture wax is not the same. It is a pity that at present, many furniture manufacturers use the imported "British wax" in order to spend less money and use the method of color finding. They also use floor wax or paraffin to make the original natural and simple color of the furniture. Will change immediately, or slowly change color and lose the original taste. Good natural wax for furniture is 150 yuan / kg or 300 yuan / kg. The floor wax is only 100 yuan in a barrel, and there is not much money in a ton of paraffin. The mystery is here. In particular, the hot waxing and baking wax technology is complicated, time-consuming and costly, which is unwilling to be done by ordinary businessmen.
6 adhesive
The traditional carp of the traditional furniture is generally better with the yellow croaker, and the more important is the shark scorpion, which is convenient for the disassembly and repair of the furniture. Both the squatting and the squatting are very careful and labor-intensive, and the heavy-duty summer is not suitable for tanning and captaining. Nowadays, some enterprises often use the imported rubber or the domestic "502" to stick the furniture structure when they are new or repairing furniture. In the future, it is generally difficult to open and repair, and the cost is of course lower.
