"Uh...... Old man, I'm scared when you say that......" Xiao Zhang suddenly smiled awkwardly.

"Hahahaha...... The old man was just joking...... However, you kid also knows too much about the counterfeiter's technique, and this knowledge reserve can almost be said to exceed that of most Tang Sancai research masters in the world. Hong Lao nodded and said.

Xiao Zhang also smiled, but continued to speak: "The old gentleman said that he was joking, in fact, in addition to the above points, there is one last way of this glaze that is also one of the skills to identify, that is, the phenomenon of returning lead!"

"The so-called return to lead phenomenon is a hundred years of condensed into the elf, part of the Tang Sancai genuine glazed lead phenomenon, that is, people often say silver spots, is a typical substance generated by Tang Sancai, the appearance of the lead phenomenon in addition to a certain environment, but also needs hundreds of years, is the time left on the special mark on the Tang Sancai utensils. Xiao Zhang began to speak in detail again.

Hong Lao didn't have much understanding of the phenomenon of returning lead mentioned by Xiao Zhang, so he asked, "What does this phenomenon of returning lead mean?"

According to the summary and analysis of the situation of these Tang Sancai objects, the first manifestation of this lead return phenomenon is that the glaze of the entire Tang Sancai ware has a thin layer of silver light, such as the color of the autumn moon floating on the surface of the object, such as a thin frost is faintly visible. Xiao Zhang said with a smile.

"But is there a second point?" asked Elder Hong hurriedly.

It is worth mentioning that the phenomenon of returning lead appears in the glaze of any color, the phenomenon of returning lead on the blue glaze is often more prominent, and the color is more natural, you must know that the glaze of Tang Sancai is composed of various chemical elements, of which the composition of lead is about 25%, since the glaze has such a high lead content, as long as the conditions are suitable, what color of the glaze lead molecule is not still running out, blue glaze is also glaze, there is no exception. Xiao Zhang continued to laugh.

Hong Lao nodded thoughtfully.

Then he gestured for Xiao Zhang to continue.

Xiao Zhang also nodded and said, " This last point is to appear on the glaze with small silvery-white spots, silver spots are an important manifestation of the phenomenon of real Tang Sancai back to lead, its manifestation is still a dynamic process that appears successively at different times, first of all, the gestation stage, the manifestation is the glaze appears faintly visible light black spots, some are slightly bursting, and then the development is in the middle of the light black spots with large white spots, and then the development is that the white spots gradually grow into white spots, with the continuous development of this process, the silver-white spots on the glaze are more and more, the size is different and the color is natural, the silver spots from the brewing to the development of silver sheets, is constantly changing and developingBut after the Tang Sancai ware was unearthed, leaving the environment where silver spots appeared, the dynamic growth process was solidified on the Tang Sancai artifact, providing us with a dynamic process to observe it, and hundreds of years of time were frozen in front of our eyes. ”

After Xiao Zhang finished speaking, Hong Lao fell into deep thought, as if he was thinking about something.

"Sir, this genuine silver spot is made up of molecules, as thin as 1% of paper. High imitation Tang Sancai silver spots, some are fired in the kiln innate, as if deliberately adding lead to melt together with the glaze, the silver spots go deep into the glaze, and the genuine silver spots float on the glaze surface just the opposite, some silver spots are imitated out of the kiln after planting, thick and clumsy, no sense of nature, and the luster of the natural lead metal is far away, although the silver spots on the imitation also use a certain temperature to melt it on the glaze surface, but the artificial traces are very strong, with the first method to make silver spots, and can not be buried in the ground with medicinal water treatment, because so the silver spots are blackened, with the second method to make silver spots not only can not make a very thin real silver spots, but also leave traces。 Even if you try your best to imitate a slightly decent silver spot, but the real silver spot appears one after another, and the growth process of different sizes, the imitator has no rut, so the silver spot is a dead knot that the high imitator can't untie. ”

Xiao Zhang said that he had completely finished what he wanted to say.

Hong Lao thought for a while, then stood up and said to Xiao Zhang: "Xiao Zhang, what you said today is of great help to the old man! The old man also happens to need to use the methods you said today to verify some things, you are like this, you should participate in the game here first, and when the game is over, the old man will come to you again, and you must do the old man a favor at that time!"

"Old man, don't worry, if there is any use to get Xiao Zhang, just ask!" Xiao Zhang said with a smile.

"Alas, as you said before, our country's research on Tang Sancai is still too little, so far all Tang Sancai's works are almost all excavated from the ground, none of them have been passed down from the ancestors, our country knows that this kind of ceramics is only a hundred years old, at that time there were a large number of Tang Sancai was directly damaged as a hoodoo, so it is a pity, our research is still not enough!"

Sighing, Hong Lao continued: "It's not a secret, Xiao Zhang, I like you very much! And I am also amazed by your rich knowledge reserve of Tang Sancai! I really underestimated you before, and now the old man is also facing some problems, that is, a batch of Tang Sancai artifacts that are about to be recovered from overseas are about to be delivered, but we can't analyze the real and fake according to the photos sent in advance, and even the news from overseas experts is not clear!" Xiao Zhang, you must know that this cultural relic like Tang Sancai represents the face of our country, and the loss of money is small, and other things are big!"

Xiao Zhang could understand the seriousness of Hong Lao's words, but he also sighed at the identity of this old man!

To be able to get in touch with something of this magnitude! It must be not easy to think about.

"The old man's surname is Hong! The old man promised you that he would tell you the old man's real name, and you can just call me Qigong!" said with a smile.

Xiao Zhang nodded, and muttered: "Hong Qigong......"

"Don't have pressure in the competition on your side, the old man just comes to see you, cheer hard, strive for a good ranking, the old man is waiting for the news of your victory at the front! And Ru Ci don't have to worry, the old man has greeted you well, and he will not punish you for participating in two competitions alone!"

Xiao Zhang was stunned for a moment, what is the situation, why can't he hide anything from this old man Hong?

This matter of participating in the Ru porcelain competition is known to others?

This is no small matter......

Xiao Zhang took a breath, then smiled embarrassedly.

"Okay, Xiao Zhang, then the old man is going to leave first, and I will tell the experts on the front line about the methods you told me tonight as a reference condition!
