Zhang Feng listened to Lao Ding's self-deprecating words, laughed, and said: "For example, parasitic in Li*? That's a good place, a man can't wait to live there every day, so you can be content." ”

Lao Ding didn't expect Zhang Feng to suddenly mention Li*, paused, and seemed to be a little surprised, but immediately reacted again, it seems that Zhang Feng has already been to Li*, and returned to his normal look, and said: "Li* has been open for ten years, and I have been there since ten years ago, if you want to talk about it, it is still those women who occupy my territory." ”

Zhang Feng knew that the relationship between Lao Ding and Li* was definitely not ordinary, and sure enough, Lao Ding had always lived there.

At this time, Lao Ding asked Zhang Feng to move the white jade to a relatively empty floor, and there was a blanket between the floor and the jade.

Everything was ready, at this time, there was a sound of "zizi ......zizi" on the desk, Zhang Feng looked over, the iron began to generate heat, Lao Ding also put on rubber gloves, ready to pick up the iron, Zhang Feng also stood up, walked to the desk and looked carefully, he wanted to know how to turn a piece of new jade into an heirloom.

Lao Ding picked up the pot of boiling strong tea and came to the side of the jade, still shaking the pot of strong tea in his hand, as if he wanted to stir the tea evenly, while explaining to Zhang Feng: "In fact, it is not only the jade industry that will do such tricks and feet, I think you have also heard that those forged letters of the era are actually similar to the same principle, and tea stains can be slightly transformed into stains accumulated over many years." ”

Saying that, Lao Ding poured the strong tea evenly onto the jade, and continued: "But paper letters are different from jade, letters can absorb the tea stains of strong tea, and then integrate them into the paper. ”

Lao Ding said on the side, Zhang Feng has been watching Lao Ding's movements, of course, his words also stopped in his ears, but Zhang Feng has some things that he doesn't understand, Lao Ding said that the paper is aged, of course he has heard such a little trick, because the tea stains are basically the same as the stains that usually see on the letters due to the passage of time, so it is easy and simple to fake.

However, there is a basic difference between jade and paper, just saying that paper is absorbent and has a low density, so water molecules can be integrated into the paper, which is common sense, nothing unusual, so there is an opportunity to forge tea stains into stains.

But what about jade? The density of jade is so large, and the surface is smooth, there is no leakage at all, let alone let the strong tea pass into the jade, even if the jade is put in a vat of strong tea and brewed overnight, it is impossible for a drop of tea to be penetrated into it.

Therefore, the same method should be used in jade, which is not applicable here. In addition, the treatment method of the letter is obviously different from that of jade, and the tea stains that penetrate the paper will still be displayed on the surface, and this is only the age effect of the letter.

Even if Lao Ding really had a way to infiltrate the tea stains into the jade, could he make this piece of white jade a long-standing heirloom? How could it be? Zhang Feng had never heard of any jade with tea stains, and he had never heard of it.

Zhang Feng was now nervous and expectant, and for a moment, Zhang Feng felt that Lao Ding was not a psychopath? He just wanted to sabotage! But since he trusted him, let's take a look at the next situation. There is no suspicion in employing people, and no suspicion is needed.

Lao Ding said what he said before, and he would stop talking, the strong tea poured on the jade just now was only a small part, but because the surface of the jade was smooth, there was no first tea into the jade at all, not even sticking to the outside, and this was also what Zhang Feng and Lao Ding expected.

Lao Ding stopped pouring tea, and looked around the situation around the jade, and finally seemed to find that there was nothing abnormal, but he didn't continue to pour tea, but put the strong tea aside, and continued to look for things in the locker, and he didn't know what he was looking for.

Zhang Feng ignored Lao Ding's actions, he was still wondering what was the use of this pot of strong tea, he had seen it several times, but he couldn't see any changes in the jade at all, so he was even more puzzled, could a pot of tea really turn new jade into ancient jade?

After a while, Lao Ding came over again, holding a brush in his hand, which was not a brush to be precise, because it seemed that the bristles on the outside of the brush in Lao Ding's hand looked soft.

In Zhang Feng's puzzled eyes, Lao Ding took the brush in his hand and put something into the strong tea, which looked like medicinal powder, and then shook the strong tea to make the medicinal powder and strong tea shake evenly.

Then he poured the strong tea on the brush again, and then returned to the jade, and was sprinkled a little more on the jade by the strong tea. Then Lao Ding rubbed it on the jade with a brush and wiped the jade all over like cleaning it.

Seeing this, Zhang Feng suddenly realized, as if he suddenly understood something, how to see whether the age of jade is new jade or ancient jade, in fact, there is controversy in the industry, some people say that to rely on what professional detection instruments, take a little jade can know the year of the jade.

Some people say that it can be seen directly from the surface, because the heirloom jade is very popular with the people who store the jade, so they will definitely clean it more, and they don't want the jade to be stained with a little dust. Because, the heirloom jade, after countless touches and cleaning, the surface will be smoother than ordinary jade.

This is the most common way to identify new jade and ancient jade, no matter how complete the new jade is, it is buried together with the stone all year round, and the layer of jade on the surface will inevitably be assimilated by the stone, so even if the surface is not visible, but in fact, the layer of jade on the surface is slightly rough. And after years of cleaning by the owner and long-term oxidation and consumption, that layer of impurities has long been removed.

Of course, jade is jade after all, and it is impossible to see this subtle difference with the human eye alone, but there is a way to identify whether this layer of jade is new or not, such as relying on scientific instruments and microscopes.

This is an extremely unprofessional, but extremely scientific approach, and everything under the microscope is completely clear. Professional appraisers will use more professional methods, but no matter which method they use, the final purpose is just to find out the new jade and the ancient jade, and see if the buyer has been deceived.

Therefore, Zhang Feng's jade, as long as it is checked by someone who knows a little bit about jade, it will be recognized that this is not an ancient jade at all, just a new jade that has just been unearthed, and what Lao Ding is doing now is to make it difficult to distinguish between true and false.

Zhang Feng finally figured out Lao Ding's move, he wanted to pour strong tea on the white jade, and then rub the jade with a brush, in fact, there was only one purpose, that is, to wipe off the rough layer of jade on the surface of the umbrella!

This is the same as the water drop stone wearing, only after time grinding, let the surface of the impurities slowly wear away, can be cleaned up, water droplets can drip through the stone.

Strong tea is rich in alkaline elements, alkalinity is corrosive, but generally the alkalinity in the tea is not large, and it is far from the degree of corrosion, otherwise people don't need to drink tea.

But just when Lao Ding was poured on the jade and brush by the strong tea for the second time, he added some medicinal powder, Zhang Feng thought, but it was the medicinal powder that Lao Ding added that promoted the alkalinity in the strong tea, so as to achieve the effect of corrosion.

Zhang Feng thought of this possibility, and the jade also squatted next to the jade like Lao Ding, and it turned out that he took a closer look and realized that those strong teas had changed, and there was a layer of floating objects like rust floating on the surface of the tea, just like tea that had been separated by several nights, and tea embroidery had been raised, and the tea at that time was the strongest alkaline.

Zhang Feng had never seen this method, and had not even heard of it, so he felt unbelievable and novel, and said: "Is it possible to use alkali to corrode the homogeneous layer? Although it is a bit lacking in morality, it is indeed practical." ”

Zhang Feng understood the old method, and felt that this time the plan to double the value of white jade would definitely work, after all, the easiest way to identify whether jade is new jade or old jade is to use a microscope or rely on the experience of an appraiser, and then take a little jade to a professional institution for identification.

Now the old method can be regarded as escaping the first two identification methods, and as for the third, there is no need to worry about it at all, after all, very few people will choose the third method. Although rich people are rich, they don't burn money as firewood every day. It's hard to buy a piece of jade, who would be bored to cut a piece of jade and take it for identification!

Lao Ding saw that after Zhang Feng understood his method, his face was full of praise, and his heart blossomed, and a sense of pride arose.

Lao Ding said: "When I quit that organization, I promised that master that I would never do these immoral things from now on.

Zhang Feng listened to Lao Ding's words, he really couldn't cry or laugh, this old man is really a treasure, obviously he saw the money himself, broke the ring, and was stunned to let him take the blame, but Zhang Feng didn't care, this time he really came to the right place, he could not only sell jade at a high price, but also learned knowledge that he had never known before.

Zhang Feng smiled: "You old fox, you don't do anything lacking in virtue, but the tools are still on your body!"

Zhang Feng remembered that Lao Ding was not a long-term worker here, but only came to the club temporarily to be a treasure connoisseur, so he brought these tools by himself, and he obviously carried the tools with him, and it is estimated that he didn't think about how to do things lacking virtue for a day.

The old fox Lao Ding laughed twice and said, "Maybe, I always carry tools with me, just to wait for you, a person who lacks virtue, to do things with me." ”

Zhang Feng and Lao Ding were joking, chatting very well, they didn't look like people they had just met, maybe this was called like-mindedness.

Not long after, while chatting and working, Lao Ding cleaned up all the jade, the surface of the jade did not look like there was any change, it was still that piece of white jade, people who didn't know, they must just think that Lao Ding cleaned up the jade, and didn't do anything.

But just one glance at Lao Ding's hands, they will know that this matter is not simple, Lao Ding's hands were originally the kind of hands full of calluses, and now the calluses are almost corroded, and the whole palm looks like the kind of rotten skin that has been soaked in water for more than ten hours, terrifying and disgusting.

Zhang Feng felt that if it weren't for the thick enough cocoons of Lao Ding's hands, the alkalinity would have corroded directly into the flesh and blood, and in order to better feel whether the surface of the jade was rubbed evenly, he could not wear gloves, and could only wipe it directly with his hands, so it would inevitably come into contact with alkaline water.

Zhang Feng couldn't help but sigh in his heart, this is really a lack of morality!
