The best way to confirm whether it is rosewood is to smell it. This method is the least destructive and easy to verify.
Sandalwood rosewood, commonly known as Indian lobular rosewood, has a faint sandalwood flavor, sweet taste, pleasant fragrance, no smoke, no choking, and no discomfort. And fakes are either tasteless or messy, which makes people uncomfortable.
Of course, there is a premise to smell. The smell of things that have been processed for a long time almost disappears, and only the obvious smell of cutting or latest processing can be smelled. If you want to ask the taste of the finished product, you need to seal it and heat it before opening it, so that you can smell the faint volatile smell.
If you seal the rosewood, cover it and heat it, you should be able to smell the faint sandalwood when you open the small mouth. That taste is sweet, similar to chocolate, but because everyone's subjective feelings are different, it can't be said to be chocolate, but sweetness is right.
It is extremely unscientific to draw traces on white paper with online rumors, and it is meaningless to draw traces on red sandalwood on white paper to distinguish between true and false. Whether you can draw traces on white paper has nothing to do with rosewood or other wood. Whether you can draw traces on white paper depends on removing pigments from wood. It's like saying that watermelon juice is red and tomato juice is red. You can't say it's all tomato juice or watermelon juice just by color, can you? What is the reason?
In addition, if the surface of the object has been stained and a layer of sludge or other dirt is attached to it, then when you draw on paper, it is the dirt on the paper that comes into direct contact with it, not the wood itself, and naturally you can't draw colors. What can be painted is not necessarily rosewood, and what cannot be painted is not necessarily not.
Red sandalwood, blood sandalwood, acid branches and many other dark red wood can be used, but only if a clean new contact surface is needed.
The counterfeiting of rosewood and Venus has always been the hardest hit. A string of beads without stars will be sold to 3-500 yuan, while the value of Venus will at least double, and the resulting huge profits will give rise to the motives of unscrupulous profiteers to cheat. Thick Venus is the easiest to cheat. Venus should see the details intermittently with a magnifying glass. That's true. There is no doubt that it is a fake Venus, if it is connected in a line without interruption.
Venus is a mineral absorbed during the growth of rosewood and deposited in the conduit (brown eye). When the wood is dried, the substance in the conduit shrinks with the drying, which naturally becomes intermittent. Fakes are generally brown-eyed wood and coated with gold powder, so it is not easy to reach the natural intermittent state of real Venus.
Venus of real rosewood is divided into thick stars and thin stars. It is obvious at the beginning of the thick star, but it is easier to fall off than the thin venus at the end of the game. In the end, there are only a lot of eyes left, which is ugly. Compared with the coarse star, the fine star is not obvious at the initial stage, but it is not easy to fall off at the later stage. After the beads are oxidized, tiny golden stars come out, which is more beautiful.
There is no necessary connection between rosewood and Venus! Venus is only the mineral absorbed during the growth of rosewood and deposited in the conduit (brown eye). So what is certain is that not all rosewood will have Venus, and the existence of Venus does not prove that it is rosewood. For example, sour branches, any piece of material has Venus, but it is not as shiny as rosewood. So don't be superstitious about the so-called Venus. It doesn't make any sense.
I hope it will help you.
