Eleven methods teach you to identify the authenticity of the lobular rosewood:
1. Take a piece of wood and put it in water. If it is sandalwood, it will sink into the water. If you sink into the water, continue to the next step.
2 , take a piece of wood on the white paper, if it is sandalwood rosewood, there are purple scars, with the same intensity for the second time, the third time ..., the scratches fade to disappear ; if there are scratches continue Next step.
3, the glass chips taken into Shengyou Qing water (the ratio of sawdust to water: volume ratio of about 1: 3 - 1: 10), sandalwood 12 hours if the water is visible through the uppermost layer (visual effects: water near the top of the glass wall and the most obvious) blue fluorescent oil-like phenomenon, fluorescence 24 hours more obvious, this step is mainly used to exclude Romer black rosewood rosewood and other non Pterocarpus timber; if Fluorescence continues to the next step.
4. Observe the color of the sawdust water leaching solution in the previous step. If it is sandalwood rosewood, it is purple-red ( the depth of the color is closely related to the location of the material, the amount of water and the length of the soaking time ); if it is purple or not sure, proceed to the next step.
5. Look at the distribution of the tube holes on the cross section. If it is sandalwood rosewood, the diameter of the inner tube hole is slightly equal and evenly distributed ; the cross section can be cut with a sharp knife, it is best not to return the knife, you can apply some water when viewing, preferably with ten times magnifying glass Or a higher magnification of the magnifying glass ; if the distribution is more uniform or not sure, proceed to the next step.
  6 , kanban surface color. If it is sandalwood rosewood, the new section is orange-red, and for a long time it is dark purple or black-violet, often with light and purple stripes.
7. Look at the growth wheel. Observe the growth wheel on the cross section. If it is sandalwood rosewood, the growth wheel is not obvious ; if the growth wheel is not obvious or it is not sure to continue the following four steps.
8 , smell aroma. If the sandalwood rosewood rubs against the object, it has a very weak scent ( like the sandalwood fragrance , but it is not the same as the burning scent that we usually smell in life ) . It smells great when it is cut with a trowel and a table saw.
 9 , look at the texture. If it is sandalwood rosewood, the texture is staggered, and some are partially curled.
  10 , look at the oil texture. If it is sandalwood rosewood, it has an oily texture ; if you can continue the next step through these four steps.
11 , the cross section is 30 times larger. This is the last step in personal identification. On the three cut surfaces of the wood, the cross section provides the most abundant information. The characteristics of the cross section should be carefully observed. Compared with the description and pictures in the national standard "Redwood", if it is sandalwood. The red sandalwood matches ( if there is no condition, this step can be omitted ) .
If the above eleven steps can be used to confirm that the wood is sandalwood rosewood, if any of the steps are obviously not met, then it can be judged not sandalwood rosewood, if there are still doubts, can be sampled ( mahjong size ) to the relevant departments ( such as the Chinese Academy of Forestry ) to identify wood species.
