Du Shengqing smiles and says in front of the owner that the object is a fake, which is also a taboo in the field of antiques.

Chuchen smiles a little and doesn't care about it. He wipes the bottom of the cup with a cloth and says with a smile: "you two have forgotten a detail. This tea cup is white."

"White birth?"

Two old slightly a Leng, then Du Shengqing frowned and said: "is it the product of Hebi kiln?"

"Do you think it's possible?" Guan Guokang said: "if Hebi kiln can produce such products, it can be comparable to the five famous kilns of Song Dynasty. Do you think its fame will be as low as it is now? Wait... "

Speaking of this, Guan Guokang frowned slightly, then came up to Chu Chen and looked at the tea cup carefully. Some suddenly said: "Xiao Chu, is this heiding?"

"Black set?"

Before Chu Chen spoke, Du Shengqing said in surprise: "Lao Guan, do you mean this is the black Ding in Ding kiln?"

"That's it!" Guan Guokang said excitedly: "when Cao Zhao of Ming Dynasty mentioned" Guding kiln "in his" gegu Yaolun · Guyao utensils ", it was recorded that" there was purple setting, the color was purple; there was ink setting, the color was black as lacquer. The soil is white, and its price is as high as that of baiding, so it comes from Dingzhou. " Look at the performance of this tea cup. It's not black set. What is it

Song Ding kiln is famous for white porcelain, but it also makes high-quality black glazed porcelain, which is called "heiding" or "rabbit hair flower". Black and white porcelain are white.

"I know about heiding, but is it going to be heiding?" Du Shengqing asked with a frown.

Guan Guokang said with a smile: "Lao Du, you are really good at bronze, but this porcelain is just the same. You know, the black setting can be roughly divided into three categories. The first category is pure black, the glaze finish is black and bright, and the light can be distinguished, just as Cao Zhao said in" gegu Yaolun "that" there is ink setting, and the color is black as lacquer. "

"This kind of black Ding has white texture, high degree of porcelain, few pores in the section, and high sintering temperature. The second kind of glaze has "Yaobian" color, or (gold, silver) rabbit hair, or oil drops, or rust spots, and even some wonderful Yaobian like, but the overall theme is black. The third type is decorated with gold color, rich and solemn.... "

"I've been lucky enough to see it darken once before, but it's just a fragment. It's the first time I've seen the whole thing!"

Speaking of this, Guan Guokang's eyes on the tea cup were full of hot. He wanted to swallow the tea cup alive.

After a while, he sighed again, "what a pity, what a pity!"

"What's your pity?" Du Sheng's strange way.

Guan Guokang said with a pitiful face: "it's a pity that such things won't be transferred by Xiao Chu! If I am willing to transfer it, I will try my best to buy it! "

Chuchen smiles and shakes his head: "as you always said, I'm sure I won't sell this tea cup."

Hearing this, Guan Guokang was still disappointed and sighed: "forget it, forget it. Now it's one more look..."

After a while, Chu Chen cleaned up the dirt at the bottom of the tea cup, and the tire quality came into our eyes.

Guan Guokang couldn't wait to ask Chu Chen for a cup of tea. Then he picked up a magnifying glass and observed it carefully. After a long time, he put the cup of tea on the table and exclaimed: "the black Ding is really worthy of its name!"

Du Shengqing also took the tea cup carefully. During this period, Du Liyu asked curiously:

"Uncle Guan, is the identification of heiding different from ordinary Ding kiln?"

Guan Guokang nodded: "that's true. In addition to the characteristics of Ding kiln, we have a formula to identify ziding and heiding. It is said that ziding is different from baiding, and heiding is different from ziding. Black purple glaze has little bubble, fat hanging purple gold clay sand line. It looks like rosin sand, black purple and iron. The proportion of temperature control and iron mixing is good, and the beauty of Ding porcelain is endless. "

"This formula means that if it's genuine, if you use a 30 to 40 times magnifying glass, you can see bubbles in the place where the glaze is thin, and you can hardly see bubbles in the place where the color is deep. The bubbles are large and small, and they are different from each other, but under the glaze there is a misty glaze layer like rosin sanding."

"In addition, the soil of heiding and ziding contains iron. The chromaticity and the amount of glaze paste stained with purple gold sand are related to the iron content, which is also very important in identification..."

When Guan Guokang said this, Du Shengqing next to him said with a strange look: "Gee, it's not right!"

"What's the matter?" Everyone looked in the past.

Du Shengqing said: "Ding kiln porcelain adopts the technology of overlaying firing, so it has awn mouth, but this tea cup has no awn mouth. How can it be fired in Ding kiln?"

Guan Guokang sniffed and said, "you are really ignorant. It's not only made in Ding kiln, but also tribute porcelain."

"I'm ignorant?"

Du Shengqing was unconvinced and said: "it's not that I haven't read a book. It's recorded in some documents that at the beginning, the reason why the court of the Northern Song Dynasty didn't use porcelain was because there was awn. But later, gold and silver were inlaid in mangkou, so it seemed that it had a high grade, so the court accepted Ding kiln. You don't even have a mouth... "At this point, Du Shengqing suddenly stopped and frowned again.

Guan Guokang said with a smile: "well, I can't go on. There is no mangkou. Of course, it can be used as tribute porcelain."

"But how can Ding kiln have no mangkou?" Du Shengqing is still unconvinced.

Guan Guokang said with a smile: "that's because you didn't read carefully. Ding kiln mangkou porcelain was created in the middle of the Northern Song Dynasty. Before firing mangkou Ding kiln porcelain, the court used not only official shadow celadon, but also Ding kiln porcelain without mangkou, which was fired in saggers."

"Due to the low production, high cost and short firing time, the number of these non mangkou Ding tribute porcelains was relatively small at that time, and it has been nearly a thousand years so far. The quantity of complete wares is very rare in the world. And it's even less like this. I guess it's probably the only thing left in the completer. "

"Later, Ding porcelains were covered with fire. Because of mangkou, the imperial officials refused to accept it. According to tanzhai biheng, a document of the Southern Song Dynasty," in this dynasty, Dingzhou white porcelains were covered with mang, which was not suitable for use. So they ordered Ruzhou to make Qing kiln wares... " That's why gold and silver are inlaid on the mangkou

"Yes Chu Chen nodded and said, "I still have a Ding kiln plate with inlaid marks at mangkou. Although the plate is of excellent quality, the fetal glaze is much different from this tea cup."

"Of course."

Guan Guokang said: "the tribute porcelain of Ding kiln in the Northern Song Dynasty has a dignified shape. The carcass is light and thin, the fetal bone is white, very delicate, and the structure is compact, which is very similar to the extremely delicate starch. Therefore, there is no gap in the fetal bone, and there is no brush mark on the surface of the carcass. The glaze is uniform, the hand feel is smooth, and it is difficult to see" tears ", and the glaze color is relatively uniform. This is much better than the later Ding porcelain, not to mention the Ding porcelain of the folk kilns. "

Du Shengqing shook his head: "Lao Guan, since you say so, I don't understand. Since you say the craft is so high, how can this tea cup look irregular?"

Guan Guokang was not angry and said: "you like to carry with me. Didn't you listen to me just now? Ding tribute porcelain is fired on the top of the sagger, and the clay is one yuan formula, so the round ware is not very round, and the caliber is not consistent. This is the characteristic of non mangkou Ding tribute porcelain. It turns out to be inferior in your mouth! "

With a smile, Du Shengqing quickly changed the topic and asked Chu Chen, "little Chu, I just heard that you picked up this tea cup. I don't know how much money you spent?"

Chuchen smiles and shakes his head. When he is about to open his mouth, Du Shengqing misunderstands the meaning. He is surprised and says, "didn't you pick it up?"

Guan Guokang was also a little surprised and said, "it's impossible. If it wasn't for the leak, how did the young man react so much just now? What's more, you can't spend tens of millions on the things on the stall, can you

At this time, Chu Yulan covered her mouth and laughed. When she told Guan Guokang about it just now, she just simply mentioned it and didn't talk about the price.

Chuchen said with a smile: "I mean, this tea cup doesn't cost money. It's just a tie-in when buying a pottery horse."

"What?! "I'll take you up!" Several people at the scene were shocked and yelled.

After half a sound, Guan Guokang shook his head: "no wonder that young man just had such a big reaction!"

"Lao Guan, what's the matter?"

Du Shengqing's face was full of curiosity. When Chu Chen said the cause and effect again, he sneered: "it's really self inflicted. As the old saying goes, babies are all virtuous. It's strange that babies will follow him if they are like him!"

Everyone nodded in agreement.

At this time, Du Liyu said: "Uncle Guan, I've been paying attention to the auction market. It seems that the Ding ware is not too expensive. What did you say just now? It costs hundreds of millions. Is this black Ding tea cup really so valuable?"

Before Guan Guokang opened his mouth, Du Shengqing said, "it's too vulgar to mention money all the time. Such a rare treasure can't be measured by money. Sometimes, even if you have money, you can't buy it."

Du Liyu smiles, but she doesn't think so. She thinks that there is nothing in the world that money can't buy, just more money and less money.

Du Shengqing looked at her daughter and knew what she was thinking. He shook his head and sighed, "I know what you think, but some things can't be bought by money. For example, the Tianmu cup in the Island Museum is only hundreds of billions of dollars according to the market value. But do you think you can buy it with so much money?"
