The wooden box is square, about half a meter long and wide, with a glossy black lacquer surface, which is very well preserved, and it looks like it has been carefully cared for, forming a strong contrast with this dilapidated old house.

Seeing the wooden box in Old Man Jiang's hand, Yu Yuan said hesitantly: "That...... Grandpa Jiang, we're here today to ......"

"Don't worry, don't worry, you guys take a look at this first." Old man Jiang didn't wait for Yu Yuan to finish speaking, and interrupted him with a wave of his hand.

Yu Yuan had no choice but to keep his mouth shut for the time being, waiting to see what important things were contained in Old Man Jiang's wooden box.

Old man Jiang carefully put the wooden box on the table of the Eight Immortals, his smug eyes swept over the two teenagers opposite, the corners of his mouth rose slightly, and he slowly opened the lid of the wooden box as if he was very excited.

Lin Yun and Yu Yuan looked in, only to see that inside was a clean blue and white porcelain altar, with no flaws on the outside, at first glance, it was a Yuan blue and white antique worth a thousand gold.

The two looked at it for a long time, but they didn't understand what Old Man Jiang meant, and they couldn't help but turn their puzzled eyes to Old Man Jiang's face.

"It's just an old man, I just got a treasure two days ago, please help me identify how much this Yuan Qinghua is worth." As Old Man Jiang spoke, his eyes kept looking at Lin Yun.

Now Lin Yun understood, it turned out that Old Man Jiang was testing himself by doing this, just now Yu Yuan said that he was an antique appraisal expert, and this old man wanted to weigh his own weight.

Anyone who is looking for someone to trade antiques, if they think that they are only shallow in learning, they will usually find a "crutch", that is, a knowledgeable person to accompany them, in the opinion of Old Man Jiang, Lin Yun is undoubtedly Yu Yuan's "crutch" now, so try his vision first, it is also the rule of the industry.

Lin Yun's face was silent, but he was secretly scolding in his heart: This time he was miserable by Yu Yuan!

Since Old Man Jiang raised the question, Lin Yun naturally had to fight, but without the assistance of professional instruments, it was a great challenge to observe only with the naked eye.

Under the gaze of Old Man Jiang, Lin Yun picked up the blue and white porcelain altar and looked at it carefully inside and out, its seriousness was probably the most attentive thing he had ever seen in his life.

When Lin Yun put the blue and white porcelain altar back into the wooden box, Old Man Jiang asked impatiently, "How is it?" ”

Lin Yun cleared his throat and said eloquently: "This Tibetan vessel carcass is thick and heavy, the fetal quality is hard, the glaze color is slightly shiny blue in white, moist and translucent, the blue and white pattern is close to the glaze, slightly concave, three-dimensional flashing, the inner wall is a sand tire, there is a sense of roughness, yin and yang light spots, the bottom is concave and circle-shaped, flint red, the outer foot circle is thicker, showing water green, it should be a Jingdezhen official kiln produced Yuan blue and white, the domestic collection will not exceed 100 pieces. ”

After listening to Lin Yun's concise comments, Old Man Jiang twisted his beard and nodded frequently, but there was still a trace of contempt between his eyebrows, as if he was holding the chance to win.

But before Old Man Jiang could speak, Lin Yun continued: "But in my opinion, this porcelain should be a fake. ”

As soon as these words came out, not only Old Man Jiang, but even Yu Yuan opened his mouth wide, he didn't expect that what Lin Yun just said was the Tao, and in the end, such a sentence would come out.

"Why do you say that my baby, old man, is a fake?" Old man Jiang became angry and shouted angrily.

On the other hand, Lin Yun said unhurriedly: "This fake is very real, every detail is quite in place, the surface is made of high-tech crystal grinding cotton, and later added a long time of playing, soaked by sweat and oil, so that the thief is lost, the glaze is warm, and the luster is soft, so that the old-timers are blind." ”

"And how can you see that?" Old man Jiang's eyes were sharp, and he stared at Lin Yun fiercely.

"It's a pity, the fake is a fake after all, the master of counterfeiting is a hundred secrets, and when copying the decoration by hand, there are still flaws." Lin Yun pointed to the lotus pattern on the surface of the blue and white porcelain altar and said.

"Oh? Where are the flaws? Old man Jiang was no longer as surprised as he was just now, and just asked flatly.

"The current Yuan blue and white imitations are all based on the real catalogue first typed paper patterns, and then hand-traced."

Old man Jiang nodded in agreement with this statement, and did not interrupt Lin Yun's words, showing a rare patience.

"The ancients used the brush since childhood, modern people use a hard pen, this habit is not a few years can be learned, from the picture, the real product will be very smooth, the imitation of the trace of the pen is slow, astringent, the skill can not be compared with the ancients, the long lines are particularly clumsy, as long as the study of the ancient Chinese painting skills, and the habit of using the brush, it is easier to distinguish imitations."

Lin Yun talked eloquently, and Yu Yuan on the side was dumbfounded, he was originally just that Lin Yun knew how to appreciate antiques as a pretense, but he didn't expect Lin Yun's profound knowledge to be far beyond his imagination.

Old man Jiang was also shocked by Lin Yun's words, but after a long aftertaste, he still said stubbornly: "Little rabbit cub, what you say is unfounded, who knows what kind of habit the ancients used to draw pictures?" ”

Seeing that Old Man Jiang had a hard mouth and refused to admit defeat, Lin Yun had no choice but to come up with the last killer move.

"As we all know, the mainstream material for making Yuan Qinghua is West Asia cobalt, and West Asia cobalt ore is a symbiotic associated ore with iron ore, copper ore and other ores, its physical and chemical structure is a unique high-iron low manganese, some of which trace elements such as arsenic oxide, can not exist alone, the temperature reaches more than 600 degrees and volatilizes, but when it is mixed into cobalt material, it is still ...... when it is burned to 1,300 degrees."

Before Lin Yun finished speaking, he saw that Old Man Jiang's face darkened, like a defeated attack, and muttered: "If the formula of chemical mixing is used, there is no such situation......

"That's right, so as long as you identify whether this special high-iron low-manganese cobalt material is used, you can roughly distinguish the authenticity of Yuan Qinghua." Lin Yun finally concluded, a smile of victory also flowed between the corners of his lips.

Under Lin Yun's reasoned and well-founded analysis, Old Man Jiang was really willing to bow to the wind and lose his heart.

Old man Jiang has been addicted to antiques all his life, and in terms of experience, he will definitely not be less than Lin Yun, but in terms of age, Lin Yun is simply when his grandson has a surplus, and he is defeated in the hands of such a fledgling hairy boy, Old Man Jiang is really a little disgraced.

Seeing Old Man Jiang's pale face, he was secretly applauding Yu Yuan for Lin Yun just now, and felt that something was not right, so he quietly stabbed Lin Yun with his elbow and asked him not to say any more.

Lin Yun understood, sat down again, and stopped judging that Yuan Qinghua.

Old man Jiang was silent for a while, then suddenly laughed, got up and patted Lin Yun's shoulder hard, and said loudly: "Little brother, your vision is really good, you can see at a glance that the old man I made this is a fake, at a young age, it is really not easy to have such knowledge." ”

Lin Yun was stunned for a while, this old man is a lot older, and he still calls himself a brother, if you want to talk about seniority, I am afraid that I will make many people embarrassed......

And when he heard that this fake Yuan Qinghua was actually from the old man Jiang, Lin Yun felt even more unexpected, it turned out that he himself was the master of counterfeiting, no wonder he knew so much about this porcelain.

In fact, Old Man Jiang's imitation level is quite superb, almost to the point of being fake, if it weren't for a master with amazing eyesight like Lin Yun, even those ordinary antique experts would be difficult to distinguish the authenticity of this porcelain with the naked eye.

In addition, the last paragraph that Lin Yun said also had some opportunistic elements, if Old Man Jiang didn't admit it, he would have no conclusive evidence.

Just when Lin Yun was secretly rejoicing, he heard a crisp sound of "bang", and then looked at the old man Jiang, there was an extra wooden hammer in his hand, and the fake Yuan Qinghua had been knocked into pieces by him.

"Senior, what are you doing now?" Yu Yuan said with a look of regret.

Although it is a fake, listening to what Lin Yun said just now, it has a ninety-nine percent similarity with the real thing, and it is easy to destroy it like this, which inevitably makes people feel worthless.

"Since the fakes are seen, they have no value." Old man Jiang said indifferently, and threw the pile of broken porcelain pieces into the trash.

Lin Yun was not reluctant at all, and said indifferently: "Now that the cobalt material has become extinct, even if the old-timers are skilled, it is difficult to make Yuan Qinghua that cannot be distinguished, unless it is ......."

"Unless what?" Old man Jiang's eyes suddenly lit up, and he asked eagerly.

Lin Yun was not in a hurry, and said slowly: "Unless you can find a cobalt mine similar to that era, although such cobalt mines have been closed now, there is still such a possibility in some undeveloped mountainous areas." ”

"Isn't this deliberately fun, old man, I'm so old, do I still have to go to the mountains to mine?" Old man Jiang said with a disappointed expression.

"Of course, you don't have to go to the old-timers in person, I just happened to know that there is such a place, and the next time you pass by, I'll bring you a little cobalt back." Lin Yun said with a smile.

Hearing Lin Yun say this, Old Man Jiang was suddenly overjoyed, took Lin Yun's hand and said, "Okay, good, little brother, you really know the old man and me too well, just rush to your heart, I ...... today"

Before he finished speaking, Old Man Jiang walked up the stairs again and disappeared at the corner of the stairs to the second floor.

Taking advantage of this opportunity, Yu Yuan gave Lin Yun a thumbs up and said with a look of adoration: "Boss, you are so amazing, even Old Man Jiang was bluffed by you, it seems that this time he is going to show a little real guy!" ”

"You didn't come to me today to feast your eyes on yourself, did you?" Lin Yun vaguely felt that Yu Yuan's excited reaction was a bit overdone, plus he knew this old mansion so well, it was obviously not as simple as two weapons.
