How to distinguish the quality of lobular rosewood bracelets?

Pterocarya microphylla contains pterostigmine, which will be oxidized when exposed to air ultraviolet rays. When it is first made, it is orange or orange-red. After oxidation, the color will gradually become darker, and finally it will be close to black, and it will still be dark purple when it is full of light. The color of sour branches will not change basically, but will turn yellow and dry after being made, and will only become darker after waxing. Moreover, there will be blue veins in the sour branches, that is, there will be blue spots, but the lobular rosewood will not.

2. Texture.

The lobular rosewood is fine in texture and fine in texture. The peaks of acid branches are obviously textured, and the texture is wider and thicker. The texture of the new material in lobular rosewood will be thicker, but there will still be a certain gap with the arrangement of the texture of acid branches, which will not be as generous as acid branches.

3. feel.

Pterocarya microphylla is the king of wood, and its air-dried density is greater than 1. Rosewood and rosewood bracelets of the same size will become heavier and heavier in hand. Red rosewood will be relatively light, and the feeling of pressing hands will be relatively poor.

4. Here are some common misunderstandings.

It is absolutely wrong to say that there is no Venus, not lobular rosewood, but red rosewood. Venus is a substance in which resins and minerals in trees are oxidized and accumulated in conduits, and many Woods will have Venus. Venus lobular rosewood has a low probability of existence, so it is rare and the price will be higher. It doesn't mean that the lobular rosewood without Venus is red rosewood.

Based on the above points, we can simply distinguish lobular rosewood from rosewood by color, weight and texture.

Requirements for the best lobular rosewood:

The first condition

It should be interlaced. That's great. We usually talk about the texture and grain of rosewood. The texture mentioned here is the pattern of rosewood, that is, the pattern of black and red interweaving. Texture refers to the brown eyes, brown lines and other textures on the surface of rosewood.

The second condition

Cow hair pattern is one of the important features of rosewood. For the "best" lobular rosewood, Venus with cow hair patterns can be seen everywhere and occasionally coexist. However, rosewood is not the only one with this brown eye pattern. Undeniably, other wood has not appeared as rich and dense as rosewood for the time being, which is certain. Therefore, it is indisputable that the covered cow hair pattern is called one of the identification methods of rosewood.

The third condition

It must be wild and long-term. The best rosewood must be the old rosewood, that is to say, it can be said that the best refers to the old material. In other words, the best rosewood is wild forest, which grows completely under natural conditions and does not need artificial maintenance and fertilization. Another condition is a long time. It is generally believed that the wild old material with a growth year of more than 800 years is the best rosewood.

The fourth condition

It should be that the whole heartwood is not cracked or repaired. There are ten sandalwood and nine empty ones, and there are other sayings, such as a hundred years of sandalwood, an inch of sandalwood and an inch of gold. These statements all reveal that rosewood is hollow and there are few octagons. Of course, it is common that the big materials in the new materials are not empty, but there are few old rosewood. Therefore, I personally think that the best rosewood should be void-free, crack-free, white-skinned and unrepaired.

The fifth condition

It must be oily, with good density and texture. First of all, oiliness refers to the kind of oil contained in rosewood after long-term growth and oxidation. This oil is more obvious when grinding wood. You can see that the places where the grinding wheel has been ground are slightly oily black, accompanied by cigarettes.
