Liu glanced at the piece of material that Chen Song was referring to, and said with a smile: "You're right, this piece is glutinous!"

"You see, the crystal structure on it is very obvious, and it feels like a cloudy glutinous rice soup, which is translucent. ”

Liu Yiyan picked up the flashlight on the desktop and shone it on it, and the piece of glutinous seed only glowed with a soft white light, neither strong nor fluorescent, but the crystal particles inside could clearly see the gap. ”

Yang Hao smiled at the remaining piece of material that could be seen with a thick crystal structure and a white surface like wax with a thick crystal structure and a white surface: "Master, then the rest of this piece is a bean seed?"

"Yes, the bean seed is a very vivid name, we know that jadeite is a kind of polycrystal, if the crystals that make up the jadeite are thicker, such as greater than one millimeter, it will be easy to be seen by the naked eye, the thick jadeite crystals are mostly short columnar, when the boundary of these short columnar crystals is very clear, it looks like a grain of mung bean, so it is called a bean seed. ”

Liu Yiyan also shone the flashlight on the jadeite sheet of this bean seed, and the light on the sheet was loose and not concentrated at all.

"Bean species are generally green, the so-called ten green and nine beans, you can see the breadth of bean species, bean species can also be further divided into: jelly beans, ice beans, fine beans, coarse beans, ......"

Liu Yiyi's answer made the two of them very intuitive and clear about the species of jadeite.

Yang Hao suddenly remembered that the master took three pieces of material from the iron frame, and only then did he take out two pieces, so he asked curiously, "Master, what kind of jade is that piece of jade that is left in your hand?"

Liu Yiyan flipped over the piece of material in his hand, put it in front of the two of them, and said with a smile: "See for yourself what it belongs to." ”

Chen Song and Yang Hao looked at this piece curiously.

The texture of this piece of material is very delicate, the bottom is like melting, the sun's rays shine on it, and it can transmit light slightly, but the background color is a little turbid, not particularly transparent, the overall feeling of transparency is better than that of glutinous seeds, and the texture is also between transparent and opaque, just like cooked glutinous rice.

"It's like a glutinous seed, but it seems to be better than a glutinous seed, but the transparency is not transparent enough. ”

Chen Song frowned, he really couldn't think of what it should be called.

Liu glanced at the tangled expressions of the two and said with a smile: "This is called glutinous!"

The two suddenly realized.

No wonder it looks like melted glutinous rice porridge with such a uniform texture!

Liu Yiyan shone the flashlight, and the light of the whole piece was very soft, very uniform, and the light was also very concentrated, not loose at all, and there were obviously no crystal particles.

"The word glutinous is actually to describe its texture state, the luster on its surface is a very soft sub-glass luster, the whole is more transparent, the grains inside are very uniform, it looks like glutinous rice porridge boiled into rice paste, the main feature is that the transparency is slightly lower than the ice glutinous species, but its base is more delicate and transparent than the traditional glutinous species, and the overall quality is higher than the glutinous jadeite, it is actually very similar to nephrite jade such as Hetian jade, but it lacks the oiliness of Hetian jade!"

Chen Song pondered for a moment and asked, "Could that be understood as the texture of the crystal particles has been completely integrated, but the transparency is slightly worse than that of the ice glutinous species?"

Liu Yiyan smiled and said: "It's almost, but the glutinous is also more transparent than the ice glutinous seed! You understand it as glutinous is that the texture is very good, very warm and delicate, but the water head is a little worse." ”

"Master, who is better, glutinous seed or ice glutinous seed?"

"These two really can't be compared, radish and cabbage have their own loves! Glutinous species are relatively delicate than ice glutinous species, and you can't see obvious crystal particles and other structures, and ice glutinous species obviously look more transparent than glutinous species, but there is no absolute between the two, I think they are the same!"

Liu Yiyan put down the flashlight and said: "In fact, these are all common jadeite species, which are basically named according to the state of jadeite from low to high, not fully evolved, and there are many uncommon textures, such as green snot, the surface is vitreous, the whole is translucent, but the jade quality is relatively pure, only a small amount of impurities of the snot ground, and the texture is uneven, only suitable for jade carving blue and white ground........"

Chen Song and Yang Hao didn't dare to slack off, and quickly remembered with their hearts.

I can't imagine that there are so many types of jadeite textures!

For the first time, Chen Song lamented the benefits of practicing martial arts since childhood.

The most direct benefit is to make yourself refreshed, your mind is clean, your memory is very good, and you can remember the explanation of the texture of a lot of jadeite with Liu Yiyan.

And Yang Hao looked a little sad, facing Liu Yiyan's explanation of a large pile of jade textures, he could only remember a rough idea, and he hated himself a little in his heart for how his memory was so poor.

After Liu Yiyan introduced this pile of various jade textures, he couldn't help but be happy when he saw the two people who were frowning and memorizing.

"Distinguishing jade is not by rote memorization, but by understanding! All of these textures are sampled on the iron frame, and they are all labeled with descriptions of their characteristics and names. ”

“......”

“......”

Why didn't you say it earlier!

Both of them originally thought that the sample was only pasted with the corresponding name at most, but they didn't expect that there was even a feature introduction!

Yang Hao suddenly put down a big stone in his heart.

Chen Song looked at the pieces on the table and found that the top and bottom sides were as smooth as mirrors, and the sides of the four sides were very rough.

With a move in his heart, he asked Liu Yiyan, "Master Liu, are these pieces already polished?"

"Yes! These pieces are fully polished on both sides!"

Liu Yiyi remembered the situation in the courtyard that day, and said with a smile: "That day, the old man poured water on the cut rough stone to show you, in fact, it was to imitate the effect after polishing by dipping the wool in water, and the wool after water can see the effect of about eight points after polishing." ”

Liu turned around, walked to the cabinet where the finished product was placed, took out two things from it, and walked back to the small table.

smiled at Chen Song and Yang Hao: "These two egg noodles are taken out of the same piece of material, you can understand it by comparing them!"

Chen Song and Yang Hao looked at the two egg noodles on the table, and couldn't help but sigh at the magic of polishing!

Both of these eggs are colorless, and one of them can be seen on the surface of very fine crystal particles, the whole one is gray, and under the sun's rays, you can vaguely see that there seems to be a ball of light inside.

The other one is transparent, without impurities, the surface of the smooth arc position flashes a white metallic luster, the egg surface seems to be equipped with a small bulb, there is a dazzling light in it to spread around, and even at the bottom of the egg surface also reflects a piece of white light on the table, under the sun's rays, the whole egg surface is filled with a continuous flow of white metallic light, indescribably dazzling and charming.

"In the jadeite industry, there is such a sentence: three points of carving, seven points of polishing, unpolished jadeite is called wool, the whole is dull, even if it is a delicate carver, can not see one or two, just like Tianhaiyi sister walking on the street without makeup, no one cares, so the effect of this jadeite polishing is like a magical makeup, can turn decay into magic"

"Master, do you actually know Sister Tianhai Yi?"

Hearing Liu Yiyan's words, Yang Hao couldn't help but exclaim.

"What Sister Tianhai Wing?"

Chen Song felt completely incomprehensible about what the two were saying.

Yang Hao opened his mouth, but suddenly found that his throat seemed to be stuck, and he didn't know how to answer Chen Song's question at all, so he had to say, "You will understand in the future!"

Chen Song could only look at Liu with a curious and puzzled expression.

"Ahem! It's just a metaphor, don't worry about the details. ”

Liu Yiyi's old face turned red, recovered quickly, and continued casually: "Therefore, for jadeite, whether it is a plain piece or a carved piece, from a semi-finished product to a finished product, in the end, whether it is high or not, and what kind of effect can be obtained, the key lies in the final polishing effect." ”

Liu Yiyan picked up the unpolished egg noodle and said: "You see that this unpolished, semi-finished egg noodle is completely in a state of no makeup, and the simplicity is faintly revealing moisture and shyness, exuding a fresh and natural innocent and lovely atmosphere from the inside out." ”

put it down, turned his hand and picked up the egg noodle that threw the light, and said with an intoxicated face: "This tossed egg noodle is like putting on makeup, it looks delicate, graceful and luxurious exudes a cold atmosphere, like a noble, dignified and peerless beauty!"

“......”

The master is the master, and it can still be explained like this!

Yang Hao endured it on the side, but he didn't dare to laugh.

Chen Song heard it a little misty, and smiled at Liu politely.

It feels like you just need to know the gap before and after polishing anyway!

I was very curious about the gap between the polishing of this jadeite before and after, and couldn't help asking: "How is this jadeite polished?"

Yang Hao took the opportunity to smile and said: "In fact, before polishing, it is polished and cut with rough tools, so its surface looks rougher, the better the jade, the higher its hardness, the finer the density, and the better the effect of throwing! ”

Liu Yi retracted his thoughts, nodded and added: "Not all jadeite can appear mirror effect after polishing, because the texture of jadeite and the water are different, so there is a gap before and after polishing, which causes a huge profit margin difference between the same quality jadeite wool and finished products. ”

Chen Song nodded understandingly.

It seems that the main thing to look at is the density of the jadeite structure, the better the crystal particles, the better the finished product, and the higher the value.

Yang Hao asked: "Master, why does the wool on the mine have to be polished after cutting?"

Oh, yes!

It is understandable that the finished product should be polished, why the wool that has not been cut for carving should also be polished, and this is an extra move?

Chen Song couldn't help but look at Liu curiously.

"The wool trade is not that simple!"

"Most of the jade dealers in the outside world buy jade, because sometimes they can't completely see through the jade, and in the case of not being completely accurate, they still have a little gambling nature, in the end, it is a piece of jadeite wool with a mediocre appearance, after cutting, the jade quality is excellent, or a piece of wool that everyone is unanimously optimistic about, but after cutting it, it is found that it has a rough texture, four lines and eight cracks, and the stubborn stone is no different, these situations in their opinion, the purchase of jadeite wool is undoubtedly a full of mystery, exciting transactions. ”

Liu Yiyan couldn't help but snort lightly in his heart when he said this, he didn't dare to say that he had dealt with the jade rough all his life, let alone those jade merchants!

"From what I just told you, you should know that the structure of jadeite will change at every stage, and even the structure will be reconstructed! And this change is caused by the geological environment in which the jadeite is located and the different geological processes, which leads to different jadeite with a variety of different structural characteristics, often ever-changing, plus the mining area in order to maximize the benefits and facilitate the shipment, the wool is basically two kinds, one is the whole rough stone, the other is to divide the rough stone into two, these two kinds of wool are relatively large, so often the jade merchants they are more difficult to see and distinguish the situation inside, the jadeite wool after polishing, can more intuitively show the contrast of the water, better let people see the situation and value inside, so as to reduce the jade merchants their worries about the risk in the jadeto increase their desire to buy, and even sometimes ...... And get them to give more money!"

After Liu finished speaking, he looked at Chen Song and Yang Hao with a smile on the corner of his mouth.
