The second is to smell it. This method is not easy for beginners to master. Use a knife or sandpaper to polish the wood surface. The lobular rosewood has a faint fragrance. If the fragrance is too strong or basically absent, it is not reliable. The common big-leaf rosewood in the market is sour, and its smell is stronger than that of small-leaf rosewood. However, the average merchant will not let you polish his good things at will.
The third is to weigh the weight. As we all know, rosewood has a high density and is submerged in water, and other wood or mahogany is lighter than it. Moreover, the rosewood has a stable shape, a warm and smooth surface and a special feel. If your rosewood weighs more than 1000, you can find this feeling.
The fourth method is alcohol soaking, which I read on the Internet. I haven't tried it yet, and I think it's not very reliable. It is said that the leaching solution of rosewood sawdust soaked in alcohol is purple with fluorescence on it.
Finally, the paperweight method is used to beat the measured object with authentic lobular rosewood paperweight. If the knock is crisp and pleasant, and there is no noise, it is generally true. Huanghua pear also has this effect. Just like hitting metal.
