Chapter 3 Convincing!
Su Lao's voice questioning was also a question from everyone present.
They were either joking or curious, waiting for Jiang Feng to give an answer, or rather, waiting to see Jiang Feng being slapped in the face.
In front of everyone's eyes, Jiang Feng sneered: "You are like this, you don't know how to pretend to understand?"
"That's right, the porcelain, moire, and seals you said are all right, and they are used to fool the layman, which is really bluffing. ”
"But in front of people who really understand, your lies can be broken at a moment's notice. ”
"Because, this is not blue and white porcelain at all!"
As soon as the words came out, the whole house was shocked.
Everyone was stunned, including Su Lao.
Everyone thought that Jiang Feng was full of confidence and would definitely tell a series of details to prove that this was a well-imitated fake.
The so-called fakes are nothing more than modernly made blue and white porcelain that is passed off as antiques by being worn.
Unexpectedly, Jiang Feng didn't even have the material of the vase, he was laughing, didn't Su Lao know blue and white porcelain!
Shocked, someone took the lead in reacting, scolding: "What are you kidding, this vase is not blue and white porcelain, then are you blue and white porcelain?
"Shut up, you deserve to talk to me?" The sharp gaze fell on the man's face, and Jiang Feng was extremely arrogant.
The man trembled, thinking of Jiang Feng's beating just now, his arrogance suddenly disappeared and he shut up.
Su Lao also came back to his senses, and said in a cold voice: "Young man, you have to talk about evidence, why do you say that this is not blue and white porcelain?"
"Very simply, blue and white porcelain is made of cobalt oxide, a mineral raw material, as a pigment, to draw patterns in the embryo of white porcelain, and then cover the transparent glaze and fire it into shape at one time. ”
"This cyan color is not a cobalt oxide component at all! In other words, no matter how perfect this vase is, it is not a blue and white porcelain in the true sense!"
"It's just a piece of high-imitation porcelain with a color pattern similar to blue and white porcelain!"
"Whether it is blue and white porcelain, you can do a redox test, and the results are clear at a glance. Jiang Feng said.
This is a very simple chemical experiment, and it is also the first theoretical knowledge that beginners learn in blue and white porcelain identification.
When cobalt oxide encounters a hydrogen peroxide solution at a suitable concentration, it will produce a reduction reaction and small bubbles will emerge.
The indigo blue and white will then be reduced to the jet-black color before the cobalt oxide was fired.
This reaction is irreversible.
That is to say, all the blue and white porcelain identified by this method, although it can be simply and rudely detected authenticity, but it will also leave indelible damage to the priceless blue and white porcelain!
Only beginner appraisers who follow the script will use this technique to confirm the identity of blue and white porcelain, and any experienced veteran will use his knowledge of blue and white porcelain to determine the attributes and age of blue and white porcelain through a vicious eye and experience.
Letting an appraisal like Su Lao do this test is tantamount to an insult to Su Lao!
He said in a deep voice: "I really think highly of you! I thought you could teach Su, but unexpectedly, you are a person who sells his reputation and reputation." ”
"I have not only carefully inspected this bottle, but also done proton analysis and microbiota differentiation evaluation. ”
"Whether it is the pattern, the bottom of the tire, or the material composition, the types of bacteria attached to the bottle, all prove that this is a blue and white porcelain produced by Qianlong, and you want me to do an oxidation test now!"
As soon as these words came out, everyone couldn't help but nod their heads, showing reverence!
The identification details are meticulous, even the bacteria attached to the bottle have been taken out for testing, a newly unearthed cultural relic, long-term in an anaerobic environment, the bacteria attached to it must be anaerobic bacteria!
Bacteria, on the other hand, can be used to guess the division algebra, and by reverse extrapolation, the age of the vase can be confirmed through the division of bacteria!
High!
Not only the bottle body is identified, but also the age of the bacteria attached to the bottle is identified, so that the two years coincide, and it is difficult for the vase to be fake!
In the admiring gaze of everyone, Su Lao took a deep breath angrily, and said abruptly: "Since you believe that I have made a mistake in identification, I will do this oxidation test as you wish!"
"But there is a sentence I have to tell you in front, if your eyesight is not good, this blue and white porcelain is indeed an antique in the Qianlong period, you must solemnly apologize to the Treasure Pavilion, apologize to me, and compensate Mr. Wang for his losses!"
"Okay, what if you lose?" Jiang Feng asked rhetorically.
A huge amount of self-confidence flowed from the bottom of his eyes.
"That is, Su is not good at learning and art, and I am willing to kneel down on the spot to worship the master! and give you all the shares I occupy in the Treasure Pavilion, and I will pay the tuition!" Su Lao was also confident.
In his opinion, he has the chance to win and will never lose, so no matter how big the bet is, it doesn't mean anything to him!
The organic guy heard the bet between the two and quickly moved out the oxidation test equipment.
Everyone's eyes were burning, and they all looked at Su Lao.
Su Lao is skilled, and the data that need to be carefully debugged in the hands of ordinary people are easy to come by in Su Lao's hands, and soon, the hydrogen peroxide solvent will be debugged and smeared on the blue and white porcelain pattern!
Minutes and seconds passed.
Small bubbles are dissolved on the blue and white flowers, and the surface glaze layer is undergoing a reduction reaction, and the result is almost unsuspenseful.
Everyone looked joking, waiting for Jiang Feng to apologize and lose money.
In the blink of an eye, the glaze is completely restored, revealing the blue and white inside.
The bubbles dissipated in the air the moment they touched the blue and white flowers.
Redox testing, at this moment, stopped!
The blue and white are still indigo, not as expected, restored to black, and the identification fails!
Everyone was stunned when they saw this scene.
"What's the situation? How can this be? This is really not blue and white porcelain?"
"But the glaze is clean. ”
"Could it be that the solution is less smeared?"
Under the doubts of the masses, Su Lao suddenly came back to his senses and re-dipped the solution and smeared it on the blue and white!
The result is still the same, the delicate blue and white indigo is a piece, and there is no intention to change color!
Su Lao stiffened, his eyes were full of disbelief, and he even threw the porcelain piece directly into the solution!
The glaze of the porcelain tiles is corroded and bubbling, but the color is solid, and there is no compromise at all.
He carefully identified the blue and white porcelain, but he didn't even pass the most basic redox test!
In a few breaths, Su Lao was already sweating, and his clothes were soaked with sweat.
He finally came back to his senses and looked at Jiang Feng tremblingly: "How could it be...... What the hell is this?"
At this moment, Su Lao's eyes no longer had half of his domineering appearance, only his eyes were full of defeat.
"I've been an archaeologist all my life, and I've worked with these things all my life. ”
"It's coming, but it's not guaranteed, I'm blind!"
Su Lao's eyes were red, his knees were bent, and he really knelt heavily in front of Jiang Feng in front of everyone!
"I lost, I was convinced of losing, and from now on you will be my master. ”
"All my shares in the Jianbao Pavilion belong to Master. ”
Su Lao did what he said, even if he suffered such a big blow and his blood pressure surged, he still gritted his teeth and held on, willing to gamble and lose.
The onlookers gasped one after another, and the faces that were originally ridiculed and ridiculed were all shocked and replaced in disbelief at this moment!
Who would have thought that this down-and-out household in front of him, who seemed to be a beggar, would easily slap Su Lao in the face and make Su Lao kneel down and surrender!
And also won the shares of the Treasure Pavilion, and turned over in an instant!
Such a big gamble is inevitably terrifying!
Who the hell is he!
Dao Dao's inquiring gaze fell on Jiang Feng's face as deep as a knife and an axe.
But seeing Jiang Feng's cold face, he didn't show any joy at all because he won the bet.
He even looked disgusted and said coldly: "Get up! You are not worthy of being my apprentice!"
The arrogant words completely petrified everyone present!
Su Lao almost spurted out a mouthful of old blood: "Why?"
"You have reckless qualifications, your heart is like a colander, and you have nothing but experience and good character, how can you be my apprentice?" Jiang Feng was unceremonious.
Su Lao's face was pale, and his lips were bloodless.
"Can you give me some advice, how can you tell that this is not real blue and white porcelain?"
