Xiao Zhang continued to smile and said: "Actually, you may also know the problem of this glaze light, the old gentleman himself, the disciple may have an axe, but in the traditional sense, if this glaze is not a person who has a little eyesight, it will not be able to see it!"

After a pause, Xiao Zhang continued: "Most of the Tang Sancai glaze will appear clam light due to the long time, it is the shadow of the millennium wind and moon left in the Tang Sancai table, no imitator can let his imitation through the millennium time, no matter what color the clam light is on the glaze are colorful, no matter what kind of light its color is also the same, the treasure light of the real three-color artifact is in a trance, such as a dream floating on the gorgeous and colorful glaze, all the high imitators will feel helpless about this dream light. ”

Hong Lao nodded, the clam light that Xiao Zhang said belongs to a relatively high-level identification method, and even some professional identification experts will look away, it is extremely easy to distinguish, and there are many counterfeiters who want to deliberately create it when they imitate Tang Sancai, but they find it too difficult...... Most can only choose to give up......

Of course, after all, most people can't see it......

Xiao Zhang continued: "Although the luster of the high-imitation three-color glaze is also soft and warm, it reveals brilliance in the softness, and there is a thief light hidden in the warmth. Although the glaze of Tang Sancai is a low-temperature glaze, it is still fired at a temperature of about 800 degrees, the glaze is still quite hard, there is no more than a hundred years of time, the glaze will not change significantly, and the clam light is the glaze molecule after the aging of the glaze, the specific light produced after the light refraction, the high imitation three-color glaze table under the irradiation of light, although occasionally you can also see light red, Light green and other colors, but if you look closely, you will find that the color in the imitation is fixed in the glaze, while the real clam light is floating on the glaze surface and is five colors and six colors, while the color of the imitation is usually one or two. ”

Hong Lao has naturally seen such works.

However, Hong Lao is very curious, if it were not for decades of Tang Sancai research, it would be impossible to say it in such detail, and this Xiao Zhang seems to have a very advanced study of Tang Sancai's identification, after all, the light fixed in the glaze displayed by this high imitation of Tang Sancai can almost confuse most people, and even he is not sure that he can distinguish it 100%!

Xiao Zhang continued: "Old man, in fact, the clam light of the genuine product can be photographed with a general camera, but the light of the imitation product cannot be photographed, so whether there is a clam light is a strong standard for distinguishing the real and fake Tang Sancai, of course, not all Tang Sancai have clam light, so it is not excluded that the Sancai ware without clam light is also genuine." ”

"So what you mean is that as long as Tang Sancai with clam light on the surface can be photographed with a camera, then it must be genuine, on the other hand, with clam light but the camera can't shoot it, it is a high imitation, but this without clam light can't be authenticated with this method!"

Xiao Zhang smiled and said, "Yes, that's what it means, this camera is a very reliable way to identify Tang Sancai with a clam light! High-tech is still very technical!"

After a pause, Xiao Zhang said again: " From the beginning of the last century to the twenties and thirties, there were a large number of three-color imitations, they have been nearly a hundred years, the glaze fire has faded, soft and warm, it is not excluded that individual utensils will have a faint clam light, but there will never be a genuine three-color kind of treasure light that gushes out of the glaze, so as long as you carefully observe the low-temperature glaze of the early Republic of China, you will find that most of the low-temperature glaze in this period is not clam light, and the low-temperature glaze of the Qianlong period will be vaguely found when you look at the side of the light, so whether there is obvious clam light can still be used as one of the hardware to distinguish the three colors of the Republic of China。 ”

"I can't imagine that you still have research on this batch of Tang Sancai?" Hong Lao was stunned......

This batch of high-quality imitation Sancai of the Republic of China has pitted batch after batch of people......

After a hundred years of precipitation, people who think they have mastered the technology of identifying Tang Sancai have suffered a big loss......

But what you get is still a fake!

"Actually, old man, I think it's because our identification technology is too advanced...... If everyone doesn't have the technology to identify it, then this batch is genuine, and the real thing can be circulated...... It's all bought and sold in front of the real thing...... Xiao Zhang said jokingly.

"Nonsense, the real is true, the fake is the fake, the first is to let the real collectors collect the real valuable things, to inherit the worthy of inheritance, and the second is not to give counterfeiters the opportunity for high profit returns! If you don't find out, don't develop and don't stop it, won't there be more and more people who make counterfeits, and when the time comes, all the goods circulating on the market are fakes, and everyone can't tell the difference, isn't the real thing worthless?" Hong Lao said angrily.

Xiao Zhang waved his hand again and again and said: "Don't be angry, old man, I'm joking, how can I really mean this, what I mean is mainly that our identification method is not perfect enough!"

"This is not perfect?" Hong Lao was stunned, he felt it, Xiao Zhang was about to say something.

"That's nature, the years are ruthless, Tang Sancai glaze has undergone the baptism of thousands of years of time, and it will also leave some traces that are not easy to find but very special! Old man, I don't know if you have any research on the authenticity of Tang Sancai glaze?" Xiao Zhang said with a smile.

After communicating with Mr. Hong about the identification methods of fetal quality and glaze, Xiao Zhang gradually felt where the old man's knowledge reserve was......

Xiao Zhang is tempting......

Crazy temptation......

The identification of this glaze is not known to ordinary people!

"The identification of glaze, this old man really wants to hear it!" Hong Lao didn't say whether he knew it or not, and directly threw the question to Xiao Zhang.

Xiao Zhang didn't continue to ask, but said: "This first point is the corrosion marks of the soil. ”

Xiao Zhang gave Hong Lao a meaningful look!

Hong Lao himself muttered, "Traces of soil corrosion?"

What does that mean?

Even if it was Hong Lao, he didn't go to the Tang Sancai excavation site to dig Tang Sancai in person!

Xiao Zhang continued: "Over the years, we should not have seen the report of Tang Sancai's heirlooms, almost all of them are unearthed, and their glazes generally show traces of soil corrosion, the difference is only the degree and method of corrosion. ”

Xiao Zhang's words made Hong Lao understand, it is true, all the genuine Tang Sancai for so many years seems to have been dug up, today a tomb was dug up, tomorrow an archaeological site, there is no saying whose ancestors handed down a treasure, it is Tang Sancai......

"Under normal circumstances, it is to see the fine pores of the soil bite appear naturally on the glaze surface at will, or the whole body or locally, the size and depth of the pores are different, some are dense, some are as few as the morning star, the degree of corrosion is different, some must be carefully observed to find, observe part of the soil bite pores under the magnifying glass, the glaze of its edge has a slight corrosion transition, after the soil is buried by the potion treatment, there will be small holes on the glaze surface of acid bites, but it is very regular, stiff and unnatural, the degree of corrosion is more consistent, and there is no transition phenomenon of corrosion. Xiao Zhang said very slowly this time, he felt that what he said this time was more profound, it seemed that this Hong Lao needed to understand slowly.

"In fact, the high imitator is very contradictory in the treatment of the glaze surface, if treated with potion, the luster of the glaze surface is unnatural, it is easy to be recognized, the glaze is too smooth and novel without using potion, adding other elements to reduce the brightness of the glaze, once the horse's feet are detected and exposed, when observing the corrosion pores, it is necessary to pay attention to distinguishing it from the brown eyes of different sizes formed by the glaze in the kiln, the brown eyes only appear on the glaze surface, the depth is about one-third of the glaze thickness, and the corrosion pores are deep into the glaze, and some are corroded to the fetal surface. Xiao Zhang said eloquently.

Hong Lao nodded, as if he understood what Xiao Zhang was saying, and then slowly digested it.

Xiao Zhang continued: "This second point is the transition of natural corrosive plaque. ”

"Excessively natural corrosive plaque?" Hong Lao was stunned again......

What is this?

Xiao Zhang smiled and continued: "Part of the Tang Sancai genuine glaze also has a special form of corrosion that is also a high imitation of Tang Sancai can not be imitated, that is, the smooth glaze surface of the extremely thin layer of glaze water is corroded, leaving a rough glaze, forming corrosion plaques of different sizes, they appear on the glaze There is a clear development process, this process is from scratch, from shallow to deep, and then from deep to shallow, after Tang Sancai was unearthed, the corrosion no longer develops, the process stops on the glaze, giving us the basis for identification. ”

"I understand what you say, I've seen this thing, but I haven't studied it carefully, Xiao Zhang, you gave me a new idea!"

"Don't dare to be, don't dare to be, this is my personal opinion!" Xiao Zhang waved his hand.

Then Xiao Zhang continued: "Then let me first say that from shallow to deep, when corrosion appears, it begins with faintly visible micropores on the glaze, and when micropores first appear, they can be several or dozens. Hundreds of thousands, when it first appeared, it was too small enough to change the gloss and color of its glaze, at first glance the glaze is normal, and it can be seen clearly without a magnifying glass; with the increase of micropores, the color of its glaze slowly becomes light brown, with the increasingly serious corrosion, the corrosion area gradually increases, there are rough patches, there is a prickly feeling when you touch it by hand, and you can scratch out the traces with a light stroke of your fingernails. ”

Hong Lao nodded slightly and motioned for Xiao Zhang to continue.

"Then I will say that this from deep to shallow, the process of developing the glaze with more serious corrosion to the glaze surface is a gradual erosion process from deep to shallow, first of all, the most serious glaze surface glaze is completely empty, only to see the rough glaze beyond recognition, with fingers can be wiped out of the traces, and then there is a slightly more serious place where the glaze surface is very thin and a very thin layer remains, but there are very fine pores and the glaze is dim, some of the glaze is almost non-existent, you can pinch it with your nails, and then transition down, the slightly corroded glaze surface looks good at first glance, and the glaze is still natural, but if you look closely at the glaze, you can faintly see the corrosion pores, and you can scratch out the traces with a knife。 ”

After a pause, Xiao Zhang continued: "This alternating corrosion process from shallow to deep and from deep to shallow, the performance of the glaze surface is measured in millimeters, but in terms of time, this process is to be formed in a hundred years, the whole artifact is easy to imitate, and the subtleties are difficult to imitate, so after eating through the glaze of the genuine Tang Sancai, and then looking back at the glaze of the imitation, its shallowness is also clear. ”

Xiao Zhang finally finished speaking, but Hong Lao was silent!

After a while, Hong Lao raised his head and looked at Xiao Zhang and asked, "I said Xiao Zhang, are you personally archaeology or tomb robbers? Or are you fake? Why do you know so much about these things?"
