Hong Lao nodded, and Xiao Zhang let go.

Xiao Zhang stood opposite Hong Lao, smiled slightly and said: "If the shape and color style of the tire glaze can be created by the master of counterfeiting, I personally can't be imitated because of the first thing, it should be the old thousand-year-old feeling." ”

Xiao Zhang's first sentence brought a strong sense of time!

Hong Lao was stunned for a moment, and suddenly became interested, and motioned for Xiao Zhang to continue.

Xiao Zhang continued: "Before the genuine product was unearthed, it was placed in a damp burial chamber, or buried in the soil, eroded by thousands of years of earth, moisture and soil, and some were placed indoors for a long time after being unearthed, affected by the changes in air and cold and warm, the fetal surface has no new ideas, old and natural, the old feeling of the genuine product is extremely natural, rich in layers and deep into the muscles, with a hard object lightly, it can be seen that the old feeling penetrates into the fetus, if possible, you can gently tap one or two places on the fetal surface in an inconspicuous place to find that the old feeling is penetrated from the fetal surface to the inside. ”

Xiao Zhang paused here when he said, these questions involve some very professional questions, Xiao Zhang doesn't know if Hong Lao can understand.

Hong Lao nodded and motioned for Xiao Zhang to continue.

Xiao Zhang continued: "The high-imitation three-color tire, although there is a sense of obsolescence after the old treatment, but there is no real tire through the erosion of the years and revealed the natural sense of vicissitudes, the old is only in the fetal surface does not enter the muscle, the new feeling is vaguely recognizable, and there will be no phenomenon of the old feeling infiltrating into the fetus." Tap the fetal table to see that the old is only a layer of the fetal surface, is the tire's clothes, unlike the real old feeling and the fetus are one and inseparable. ”

After Xiao Zhang finished speaking, he smiled and added: "This is what I think is the first way to really distinguish between true and false Tang Sancai! I don't know if the old gentleman is satisfied!"

"It's kind of interesting! Go on!" said Hong Lao with interest.

Xiao Zhang nodded and continued: "This second point is more of a test of operability, this method is a new section of the fetal soil that changes color when it encounters air. ”

Speaking of this, Xiao Zhang stopped, basically a similar name appeared, Hong Lao should be able to distinguish its general meaning, if he can distinguish it, Xiao Zhang continued to say it in detail.

Seeing that Hong Lao didn't seem to show a thoughtful look, Xiao Zhang continued: "Due to the long time of this genuine Sancai, after some of the new sections of the fetal soil meet the air, the color of the fetal soil will gradually change from white to black, this process is generally about 100 days, and some genuine Sancai will also appear on the fetal surface after washing. ”

After a pause, Xiao Zhang continued: "And the new section or tire surface of this high-imitation three-color tire is three or five years, and its white tire soil will not change significantly. ”

Xiao Zhang looked at Hong Lao and nodded, as if agreeing with Xiao Zhang's statement, Xiao Zhang continued.

"Old man, the disciple has seen a book about the method of distinguishing between the real and the fake Tang Sancai, that is, Cheng Jinkui has such a statement in the article "Tang Sancai Distinguishing the Fake and the New Knowledge": It is said that the real product is put into the water, and after it is taken out, it will appear moderately pink, and the imitation will be earthy white when it is put into the water. ”

Xiao Zhang said this, looked at Hong Lao, obviously this Hong Lao knew this method!

Hong Lao smiled and said: Regarding this method, the old man has tried it many times, and the results are the same, but this medium pink shape is slightly pink compared with the dead gray and white of the imitation tire, and it seems that it is more suitable for Henan tires alone. For example, the imitation tire color copied in Luoyang and other places is slightly pink, and it shows a more eye-catching pink when placed in water. ”

Xiao Zhang didn't expect that this old man was just unusual, it would be very good to say it himself, this old man had also tested it himself, this is a master!

"Since the old gentleman has experience, then I won't say much, then I'll talk about the third way. Xiao Zhang smiled.

Hong Lao also nodded, and looked at Xiao Zhang's eyes more and more like.

The knowledge that Xiao Zhang has mastered is not at all the knowledge that a young man of such age should master, this is clearly the knowledge that only an old pedant who has studied Tang Sancai for many years can understand!

"The third method is that some genuine three-color exposed tires will produce very fine dark red, light brown, black and other colors of rust such as the tip of the needle. After Xiao Zhang finished speaking, he looked at Hong Lao.

Hong Lao was thinking and nodding slightly.

Xiao Zhang continued: "This fine rust is more or less dense and sparse, and appears more or less on the surface of the exposed place, some on the edge of the mouth, some on the pedal, and some on the utensils. Rust is not innate, nor is it generated in one day, thousands of years of gestation so that some element molecules in the fetal body overflow from the fetal surface and become an integral part of the fetal surface. ”

"That's right, this rust has become a part of Tang Sancai after thousands of years, and it can't be done by post-processing or counterfeiting!"

Xiao Zhang continued: "This high imitation three-color tire surface will never appear soil embroidery, imitation rust is extremely unnatural, imitation out of the kiln and then to the exposed place of the rust and natural growth of the real rust color difference is very different, the growth and strong addition, a natural, a stiff unnatural. ”

"Okay, this is a good way, a really good way!"

Xiao Zhang also smiled.

"Do you have anything else to say?" Hong Lao seemed to notice that Xiao Zhang wanted to speak and stopped......

"Yes, old man, the disciple hasn't finished yet!" Xiao Zhang nodded.

"Go on!" Hong Lao also said happily.

"Rust seems simple, but it is extremely difficult to imitate, so most of the high imitation Sancai in order to minimize man-made flaws, simply do not do rust, and even some counterfeiters understand rust as the surface of the soil can be washed off with water dirt layer, in fact, the so-called rust, is the product of chemical changes in the substance, such as rust, patina, etc., it is inseparable from the original, the real Sancai rust not only can not be washed off and the more washed more clearly, so this rust I think is currently the most reliable way to distinguish between the true and the false Tang Sancai!" Xiao Zhang finally finished his words!

Hong Lao stood up suddenly and patted Xiao Zhang's shoulder, and then said with a smile: "Good boy, the old man really didn't mistake you!

"The old gentleman has it!" Xiao Zhang said very modestly.

"Actually, sir, I have some other ways......

"What do you mean?" Hong Lao was stunned......

"Old man, what I said to you before this belongs to distinguishing the authenticity of this Tang Sancai through the fetus, in fact, there is a saying through the glaze!" Xiao Zhang said with a grin.

"Oh! Tell me about it!" Hong Lao found that Xiao Zhang was like a treasure trove......

He was really knowledgeable and talented......
