The starry sky is thinning, the Milky Way is slowly fading, and the eastern horizon is dyed with a faint glow. The glow of the sun extends from pale to orange-red to golden yellow.......

Until the horizon is embraced, the white clouds are slightly purple and crimson, and then fade away, and the sky and the earth are vast......

Finally, half of the sun wheel appeared on the horizon.......

"Whew~!"

Facing the morning glow, Chen Song stopped exhaling and slowly exhaled a mouthful of turbid qi in his body.

After a night of cultivation, the vitality in the sea of qi has been replenished a little, and there is no longer the feeling of weakness that I had yesterday!

The condition in the body is quite satisfactory, and I get up energetically and go to wash up.

After breakfast, follow the brigade and continue into the huge pit.

Although it was the second time he saw it, Chen Song was still shocked.

Yang Hao looked at Chen Song suspiciously all the way, feeling that this kid's body's recovery ability was too strong!

I can't figure out how this kid feels like a different person overnight!

The mental state and strength are simply many times better than yesterday! It is completely different from the boy who was hung up like a dead fish the day before yesterday!

If it weren't for the shabby denim clothes on his body that affected his image too much, he would have wondered if the son of a family had come to inspect the mine.

In the morning, he followed Yang Hao and continued to dig in the place he dug up yesterday.

Chen Song took advantage of Yang Hao's free time and asked Yang Hao the questions he observed yesterday while digging.

Yang Hao was shocked by Chen Song's question about jade identification, he couldn't imagine that this kid's observation ability was so strong!

Speaking of jadeite, Yang Hao's whole person was full of energy, and he couldn't help but introduce some information about jadeite to Chen Song:

First of all, the points that Chen Song observed were correct, and those things that looked different from ordinary stones were all because the stones contained jadeite characteristics.

Because the jadeite rough is weathered in the process of geological transportation, it forms a layer of weathered shell wrapped around the stone on the surface, which is also called "skin shell". The rough jadeite with a coarse weathered shell and a sandy feeling is also known as sand stone.

Therefore, as long as there is an obvious sense of sand grain, pick up the weathered shell stone that feels pricked, and it can basically be judged to be a jadeite rough stone.

For the identification of jadeite rough that is not much different from the shell of ordinary stones, it is mainly through the observation of various phenomena on the surface of the weathered shell to infer the internal quality of the jadeite rough.

That is, what Chen Song observed yesterday, the surface of the stone containing jadeite is different from that of ordinary stones!

The convex thing that Chen Song saw on the surface of the stone in the form of zigzag veins was called "python", which refers to the expression of the green bands in the jadeite in the weathered shell.

Generally, it is distributed on the surface of the weathered shell in the form of convex zigzag veins, like a python coiling, which is a basis for judging whether there is color and the state of color distribution.

The diagenesis and mineralization of jadeite have different generations, forming differences in structure and composition, which leads to different hardness, so differential weathering occurs in the weathering process.

Generally, the fine-grained dense structure has stronger weathering resistance than the coarse-grained loose structure, and the green part is also stronger than the colorless part, so compared with the base of the colorless and light-colored coarse-grained loose structure, the green part of the fine-grained structure protrudes to form a python belt.

The green bands of jadeite are mostly the result of the transformation after the diagenetic period, which is first to deform and rupture the jadeite rock under the action of stress, and then be invaded by the hydrothermal fluid containing chromogenic ions for ion metasomatism to form green bands.

Therefore, the colored bands are mostly deformed fracture zones, and this fracture zone continues to be crumpled and recrystallized under the action of stress and hydrothermal fluid, forming a curved jadeite ribbon with a dense structure, which is directly reflected on the weathered crust on the surface of the jadeite rough.

The shape, color, direction, and tendency of the python belt have also become an important symbol for judging the change of emerald green.

On the surface of the stone that Chen Song saw, there are marks of different sizes and shapes, which are black, dark green or gray, which are called "ringworm", which appear on the surface of the raw material shell of jadeite, which is a kind of performance characteristic associated with the emerald green color, which is the provider of chromium ions, commonly known as "ringworm eats green" or "green goes with black".

The main mineral component of ringworm is alkaline amphibole, which is usually a columnar, fibrous aggregate, indigo-blue, blue-black, and often surrounds pyroxene, especially jadeite, which is marginally metasomatized or completely metasomatized, and has obvious color changes with the material around the shell.

If there are a large number of patchy ringworm on one surface, and there are a large number of punctate ringworm on the other side, then there may be too much actinolite and other minerals inside; if there are some ringworms that are only manifested on one surface, and they are all patchy ringworm, it is possible that there is only a little "dirty" on the surface, which will not have a great impact on the internal jadeite; if there is ringworm on two or even three sides, it is possible that the jadeite contained inside is not pure in color or has many impurities, so the jadeite in it is not of high value.

There is also a kind of green expression on the jadeite shell called "pine flower", which is a manifestation of the inner or light green of the jadeite on the surface of the shell.

Since the type, concentration and spatial distribution of chromogenic ions are relatively stable in a certain metallogenic time and space, the change and distribution of the internal color of jadeite can be inferred according to the color intensity, quantity and morphological changes of pine flowers.

If the color of the pine flower is strong and bright, the value will be high, if there are no pine flowers on the jadeite shell, there may be few colors on the inside, and if there are pine flowers in many places on the skin, there may be color inside or only on the surface.

In addition, whether the pine flower penetrates into the jadeite, the depth of penetration, etc., is also one of the bases for inferring the quality of the color.

There are also some jadeite rough stones with large cracks or direct fractures, which can directly distinguish the quality of jadeite!

After Yang Hao's answers, Chen Song finally understood how to distinguish whether there was jadeite in the stone!

"As for going further, for the specific value judgment of jadeite, either cut it and look at it directly, or rely on the judgment of the jade master. I don't know much about this now, so I can't tell you. If you are really interested, you will understand when you have the opportunity to become a Xiangyu Master one day!" Yang Hao said helplessly.

"Brother Yang, you know jade so well, haven't you become a jade master yet?"

"Xiangyu Master? hehe...... Yes, I will definitely become! And I will still be the best jade master!"

I don't want to be a Xiangyu master, thinking of all kinds of things.

Yang Hao smiled bitterly and clenched his fists inadvertently.

"Don't talk about it, keep digging!"

Yang Hao felt very uncomfortable in his heart, as if he was blocked by something, and didn't want to continue to talk about this topic.

Chen Song saw that Yang Hao was a little sad, and he didn't want to talk anymore, so he couldn't continue to ask.

But in his heart, he was secretly curious about Yang Hao, because every time he mentioned Xiangyu Master, Yang Hao's mood fluctuated greatly, and there must be a story in it!

Chen Song followed behind Yang Hao, while digging, combined with the common manifestations of jadeite rough that Yang Hao just said, to judge whether the stone contains jadeite.

When carrying the stone that Yang Hao has confirmed to contain jadeite, he constantly observes and ponders the surface of the rough stone.
