Liu Yan shook the egg in his hand at the two of them.

The egg noodles are full of fluorescent flows, and they are beautiful.

"Like this kind of water is an excellent glass jadeite, usually the fluorescence will be stronger, rich in metallic luster, but there are also a few glass jadeite fluorescence will be relatively weak, or even no fluorescence effect, this is actually related to its own water bonding, the finer the species, the better the water, the combination of the two fluorescence will have a strong feeling, so the jadeite species and water, these two are indispensable.....!

Liu stopped at a glance and asked, "Do you know why?"

Seeing that both of them shook their heads, Liu Yiyan sighed: "That's fraud, there are many people on the market who specialize in making fluorescence effects to mislead people, and this needs to be paid attention to in the finished product!"

Chen Song and Yang Hao were stunned for a moment, and couldn't help but look at each other and smile bitterly.

Liu Yiyan just said that the strong fluorescence is a good combination of water, since the two are indispensable, then the fluorescence is strong jadeite and not necessarily glass jadeite, then there is only a fake!

"The water of ice jadeite is inferior to that of glass species, but it also fluoresces, usually showing relatively weak fluorescence, or no fluorescence, which is also limited by its own seed water. ”

Liu Yiyan put down the egg noodle in his hand and picked up the ice seed sheet.

Flipped down against the sun's rays, the fluorescence on it was indeed not as much and dazzling as the fluorescence of the glass species.

After putting it down, he picked up the piece of ice glutinous seed and shook it against the sun's rays, and said: "The transparency of the ice glutinous jadeite is worse, generally speaking, when shaking the jadeite, this faint and hazy white light can also be observed, as for other types of jadeite, there will be basically no fluorescence." ”

Yang Hao said: "In other words, the jade that can shine must be consistent with the combination of water and water, and its texture must be at least above the ice ground!"

"Yes!"

It seems that jadeite is really complex and diverse!

Species and water are inseparable, but they belong to the two familiar aspects of their respective developments, and only when both are at the top can they be called the best jadeite.

Chen Song couldn't help but look forward to the head of the jade.

Yang Hao also said a little impatiently: "Master, then you can tell us about the jade head!"

"Good!"

Liu Yiyan saw the studious appearance of the two, and felt relieved.

People who are eager to learn are liked by their teachers!

It's not just a matter of worry, it's more about the sense of accomplishment that students can bring to themselves after learning quickly!

"Generally speaking, the water in the jadeite, is the same as the water, clear and translucent is better, slightly turbid for the medium, if it is the same as the quagmire, not much light, it must be the next grade, simply put, the head of the jadeite refers to the size of the light transmission range in the jadeite, that is, the transparency of the jadeite itself, the head of the water is long, the head of the water is good, on the contrary, the head of the water is poor, the head of the water is short, the transparency is not good. ”

Looking at the two who were listening carefully, Liu Yiyan smiled.

"In the jadeite weathering degree is enough, the grain is fine, the structure is compact, the bottom is pure under the condition that the water can be produced, it is more than the transparency of the optical phenomenon, there is water must be transparent, and transparent is not necessarily water, such as ice slag, so the water is good jadeite species will not be bad, but the good planting does not necessarily have water. ”

Yang Hao asked: "Master, if the species of jadeite are all the same, is it true that the better the water head, the higher the value?"

"It can also be said that the water head is good, the jadeite with high transparency, itself is crystal clear, no matter what color will appear fresh and smart on it, in terms of value, since ancient times, there is a water increase of one point, silver increases by ten taels, the color is one level higher, and the price is ten times higher. ”

Liu turned around, walked to the cabinet full of finished products, took out two egg noodles from them, and returned them to the table.

Of the two eggs, one is close to full green, but it doesn't feel like it, and the other has a hint of divergent green on it.

Liu glanced at the two egg noodles on the table, and said: "As the so-called no yang does not look at the jade, the strength of the light and the change in the thickness of the jadeite have a great impact on it, the intensity of the light source is close to the sunlight at noon, and the water head of the jade is relatively accurate, on the contrary, if the intensity of the light source is very weak or cloudy, then the water head of the jade is not accurate enough, so don't look at it at noon, because the intensity of the light will look at the water head longer." ”

He pushed the two egg noodles in front of Chen Song and Yang Hao, and asked, "Have you noticed the difference between these two egg noodles?"

Yang Hao replied with some excitement: "The water heads of these two egg noodles are different!"

"Yes, one of them is a glass species, and the other is an ordinary ice species. ”

Liu Yiyan picked up the egg noodles with a hint of divergent green, and said: "This ice jadeite, although there is green in it, but the water head is insufficient, and the performance is always worse, because the light cannot penetrate into the inside of the jadeite, the color can only stay on the surface, so there is only a slight mapping divergence, compared with the three-dimensional color change, it is always worse."

Stretched out his hand and picked up the other egg noodles that were close to full green, and said: "And this egg noodles that belong to the glass species, it can be said that it belongs to the very good jade of the water head, and the trace of emerald green floating in it looks very pleasing to the eye, and you can also see the change of the shape of the floating green, which is very three-dimensional!

"Jadeite water and species to be in harmony with each other, such as the old color is very good, the water is good, the impurities are less dirty, set off each other, you can fiercely set off the jadeite beauty, moist and value, good jadeite, its ground structure should be delicate, the color should be uniform, the impurities are less dirty, there must be a certain transparency, can play a role in the blend of ground and water, set off each other, can be called the ground good, and the water is not good jadeite is called the ground dry or bottom dry. ”

Placing the two egg noodles on the same palm, he smiled: "Now you understand the meaning of planting water for jadeite, right?"

"Got it!"

"Clear!"

Looking at the two egg noodles next to each other on Liu Yiyan's palm, compared to the level of the score, where can the two of them not understand!

Such an obvious way of teaching is that even a pig must understand!

Liu Yiyan felt that the samples collected over the years were finally in vain.

If I could have had such learning conditions, I guess I would have avoided decades of detours!

"Of course, the value of jadeite, but also need to match the color, size, shape to price, in short, jadeite this thing has no specific price, not entirely according to the water to price, or look back at the jadeite itself, which is also rich in too much knowledge, we need to continue to explore and learn. ”

Liu Yiyan sighed.

There is no end to learning, who dares to say that they can really see through jadeite?

I am already quite accomplished in the jade world, but I still don't dare to say that I know jadeite, I can only talk about a little understanding!

Outsiders think that they can see the jadeite clearly, only they understand that this is to minimize the internal risk of the jadeite, no matter what, they have a little more chance of winning than others, and no one dares to say that they can see through this thing 100%!

Xiangyu is a rigorous academic, a kind of water color and ground cracking, which link is just a little worse, and in the end it will be a loss.

The more you know, the more ignorant you will discover!

It's just that I can't tell the outside world!

"Master, is there a specific division of this head?"

Yang Hao's question pulled Liu Yanyan's thoughts back.

"Yes!"

Liu Yiyan turned around on the iron frame, took out five pieces of material, put them on the table, and lined them up in turn.

"Transparency refers to the degree of light transmission of jadeite, and the standard is to divide the transparency of jadeite into five levels: transparent, sub-transparent, translucent, slightly transparent and opaque. ”

"Master, is this what these five pieces of material look like?"

"Yes, it's literal, it's easy to remember!"

"Most of the light in this piece can be seen, and the internal features of the jadeite are clearly visible, which is transparent. ”

"Most of the light is transparent, and the internal features of the jadeite are sub-transparent. ”

"And this part of the light can be seen, and the internal features of the jadeite are still visible translucent. ”

"This small amount of light can be transmitted into the interior of the jadeite, and the internal features of the jadeite are vaguely visible and slightly transparent. ”

"In the end, this piece of light cannot penetrate the inside of the jadeite, and the internal features of the jadeite are not visible and are opaque. ”

Liu Yiyan pushed the piece forward as he introduced.

Chen Song asked curiously, "What about ...... Master Liu, how do you divide the jade that belongs to the original stone?"

After all, the original stone can't be seen as transparently as the cut jadeite!

"The original stone can not accurately see the texture of the jadeite, but it can be measured according to the halo of the strong flashlight to measure the quality of the jadeite head, referred to as a few points of water, generally divided into one to three points, three points of water is the most transparent, one point of water that is the depth of light transmission of about 3 mm, two points of water transmittance depth of about 6 mm, three points of water transmittance depth of about 9 mm. ”

Liu Yan paused and said, "You wait for me for a while." ”

Under the puzzled eyes of Chen Song and Yang Hao, Liu walked out of the room at a glance.

Soon, Liu Yiyan came back with two dark green boxes and handed them to Chen Song and Yang Hao respectively.

"Master Liu...... This is?"

Chen Song took the box suspiciously.

"Thank you, master!"

Yang Hao took the box directly and excitedly, and when he heard Chen Song's question, he hurriedly said: "This is the strong flashlight used by Zhaoyu!"

He has always wanted to buy one, but this kind of professional flashlight is not easy to buy, and he is embarrassed to tell the general.

"Thank you, Master Liu!"

After knowing that it was a flashlight, Chen Song was extremely happy.

I used this thing just now, which is equivalent to being able to see the structure inside the jade at any time!

I hurriedly opened the box and saw a beige, box-like square flashlight, as well as a charger and two batteries, and I was very happy!

"If you like it!"

Seeing the happy look of the two, Liu Yiyan was also very happy.

Give people roses and have a lingering fragrance!

Sometimes that's how it is, sharing spreads happiness!

"The strong light flashlight can help us observe the water and cracks in the jadeite, for those just mentioned, you can digest it yourself, in addition, you can also study the samples in the house by yourself, there is no shortcut to identify jade, only to see more and summarize!"

Liu Yiyan admonished, turned around with a smile, and walked out the door with his hands behind his back, leaving the two people who were excited to study the flashlight in the room.

I sighed at the change of time in my heart......

When you are young, it is so simple to be happy!

Now that I am older, after the ups and downs of life, I like to be more bland, and I have also understood and thoroughly learned the simplicity that I had at the earliest!
