Look at the skin first and then weigh it with a pair of good walnuts

Now, Wen Play Walnut is rich in variety. When purchasing, we should first pay attention to avoid walnuts with defects in the skin, which will affect their value.

Yellow-tipped flower skin is a common problem in picking walnuts. The yellow tip refers to the yellowing of the color of the walnut tip, and if the surface color of the walnut pattern is not uniform, there are many yellowing places, which is called "flower skin". The "golden tip" known as it is only a marketing means for individual businesses.

The pubic skin is a fatal flaw in the walnut. Severe pubic skin will increase with the time of play, the color will become darker and darker, so when you encounter a wen play walnut with a pubic skin, it is best not to buy it.

Insect-eye chaff skin is also a defect of the walnut itself, which has a great impact on the market value of the walnut. The worm eye is because the walnut is still in the growth stage, and the worm enters the green skin of the walnut to harm the walnut, leaving a worm eye on the core bone. It is generally possible to see it on closer inspection.

Relatively speaking, the color difference problem that people often worry about is not a particularly large flaw. Often after a period of disk play, the color difference will become smaller and smaller, and most of the existing color difference will eventually disappear. However, this is a test of a person's patience, and it is impossible to plate the effect of old walnuts in a very short period of time.

In addition, to identify the quality of walnut cortex, you can also refer to the weight of walnuts. Before purchasing, you may wish to weigh the walnuts on your hands, if there is a feeling of pressing the hand, it means that the cortex density of walnuts is large and the bone quality is good. If it is placed on the hand and fluttered lightly, it means that the cortex of the walnut is not very good.

Under the premise that there is no problem with cortex and density, pairing is an important indicator of appreciating walnuts. Pairing to first look at the pile type, two walnut pile type similar, and then look at the size, the side of the belly height size is the same or very similar and then look at the grain, the closer the grain, the better, but not exactly the same, unless the resin counterfeit walnut. After all, walnuts grow naturally, just like "there are no two identical leaves in the world", it is rare to be able to pick out two highly similar walnuts among many walnuts.

As for how to choose the size of the walnut, the author feels that it depends on the feel of their own play, too big to take it easily, too small to let go of the hand and no feeling, so the size is the best.

In addition, now the identification of walnuts also involves the problem of knife repair and maintaining the original ecology, and many playing families argue endlessly about this.
