"That's it. I said, this is an autumn auction preview, not an autumn concert. The starting price of this piece is not high, in addition to being damaged, there is another reason. ”

"Uh-huh, what's the matter, is that okay?"

"I can only barely say that it is a generation. Yu Yao pointed to the white porcelain bowl, "This is a fixed kiln in the late Northern Song Dynasty, and the craftsmanship is relatively rough." ”

Xie Zhihao suddenly came to his senses, "In the late period, how can you see it? It's not that I can see it in the early Northern Song Dynasty, in the early period, it was burning, and it was impossible for the bowl to have 'mang' at the mouth." But in the middle and late stages, can you break it down again?"

Xie Zhihao's so-called mango refers to the rough part of the exposed fetus.

In the early Northern Song Dynasty, the kiln was used for positive firing, such as a bowl, the bottom of the bowl was rushed down, and the mouth of the bowl was rushed up, which was positive firing.

In this way, the bottom of the bowl will "hit the ground", and there will be a circle or even a whole bottom that will be exposed.

After firing, the bottom of the bowl is much rougher than before burning, and there is an uncomfortable grinding feeling to the touch, which is called mang.

In addition to grinding hands, such porcelain also has a problem, it is easy to damage the furniture. The furniture is generally wooden, and the light at the bottom touches the tabletop or something, which is also easy to cause wear marks.

Therefore, after the middle of the Northern Song Dynasty, the kiln created the method of overburning. Of course, small mouthfuls can't be burned, such as plum bottles, which are unstable, mainly wide-mouthed things, bowls and jars.

Xie Zhihao could see that it was not early, that is, because the mouth of this Dingyao flower bowl had a circle of mangs, which was burned.

In fact, there is a mango in the mouth of the bowl, and there is also a problem, if you take the meal and drink the porridge, if it is against the mouth, it is easy to pull the mouth. Mang, there is also a call called "astringent mouth".

However, this problem can be solved with inlays, which were a popular style in the Song Dynasty, such as the gold-topped incense burner that Yu Yao encountered earlier. The royal inlaid gold top, the common people can be inlaid with silver and copper.

It can be used without a mouth, just stay away from the mouth. The key is that the overfiring technology is beneficial to the kiln mouth and can increase the output.

One thing has to be mentioned is that the mangs of the Dingyao kiln are also one of the reasons for the Ru kiln.

Because "Mang" was a shortcoming after all, Song Huizong couldn't stand it in the end.

"Dingzhou white porcelain is unusable, so Ruzhou was ordered to make celadon."

Ru kiln, is a special official kiln, from the selection of materials to the process, extremely exquisite, coupled with the short survival time, which leads to its preciousness.

Ru kiln solves the problem of "mang" with "nail burning", the whole vessel is full of glaze, and there are only a few sesame marks caused by a few nails at the bottom. Sesame marks have also become one of the important features of Ru kiln.

Yu Yao shook his head, "You look at the astringency of the bowl, it is obviously irregular, and there is neither polishing nor traces of inlay, which means that it has not been seriously dealt with at all." In the late Northern Song Dynasty, because Huizong of the Song Dynasty disliked the Dingyao to create the Ru kiln, the overfiring of the Dingyao began to turn to the positive firing again, and the overfiring at this time was more sloppy and the astringent mouth was more irregular. ”

Xie Zhihao nodded in a deep voice, "Makes sense······"

Then he asked, "The late Northern Song Dynasty can be said to be reasonable, but I think this process is okay!"

"A generation of famous kilns, of course, the craftsmanship is not much worse, I say rough, it is relative. Look at the scratches on this bowl, simple and plain, there is no special beauty. In the late Northern Song Dynasty, the printing technology was already very mature, and this bowl was still scratched, and it was not exquisite enough, isn't that rough?"

The dark pattern decoration on the glazed surface of Dingyao porcelain is also its more significant feature. Generally, there are three technical means: scratching, engraving, and printing.

Scratching is the earliest process, the use of grate tools, the decoration is relatively simple, to put it bluntly, the artistry is poor, and the general craftsman can do it. It mainly appears on early kilns and ordinary products.

Engraving is developed on the basis of scratching, with more tools, meticulous craftsmanship, and a strong sense of three-dimensionality.

Printing, the most expressive technique of Dingyao porcelain, only existed in the middle of the Northern Song Dynasty, and was already very mature in the late Northern Song Dynasty. The pattern is clearly layered, and there is often a back-grain interval between adjacent ornaments, and the printed ornament is also the most complicated, but it is complex but not chaotic.

What Yu Yao said is the truth, this Dingyao white glaze scratching bowl is indeed not a high-quality product.

Xie Zhihao nodded again and again when he heard this, "Alas, in this world, there is really nothing cheap to pick up! The starting price is low, and there is a reason why it is low." ”

"Of course, can such a bowl be compared with a Dingyao bowl that costs tens of millions?" Yu Yao said, "If it is such a good bowl, I'm afraid the owner may not be willing to take it out." ”

Xie Zhihao suddenly rubbed his temples, "Brother, why do I feel that my thoughts have changed a little bit during the period of dating with you?" Is there some good things that I should keep and collect and appreciate by myself." I've been in the antique business for so long, and I haven't kept a good thing for myself, so I just went to make money!"

"Didn't you say that you like to make money, you appreciate money, what else do you keep?"

"You don't know, I just suddenly remembered that I once shot a 'Hongding' string pattern lid jar, I liked it at the time, and I really had the urge to leave it myself, but in the end, I still made a move. ”

"I'll go, you still have anything to do with 'Hongding'? I haven't seen it!"

Red Ding, red glaze Ding kiln, the color is dark red, and some people call it Ziding. Su Dongpo once wrote: Dingzhou flower porcelain red jade.

There are not only white porcelain, but also red porcelain and black porcelain. White porcelain and black porcelain are relatively common, and red must be rare and precious. Not only is it precious now, but it was very precious in the Northern Song Dynasty, and like Ru kiln and Chenghua Doucai, this dynasty is a rare thing.

There is such a historical record about Hongding. It is said that when Song Renzong arrived at Zhang Guifei, he suddenly found a piece of red porcelain from the Dingyao kiln, and asked her where did you get such a good thing? Zhang Guifei said, Wang Gongchen sent it. Wang Gongchen was a minister and a famous poet at that time.

Although Song Renzong was very fond of Zhang Guifei, when he heard this, he was annoyed, picked up the pillar axe, and smashed this piece of Dingyao red porcelain on the spot!

Of course, the main reason why he was angry was that the concubine had a relationship with the minister and received gifts privately. But it also shows the preciousness of Hongding! If you give two catties of local products, maybe Song Renzong will not only not be angry, but will also taste them together. However, if you want to shoot the concubine's fart, how can you handle ordinary things?

This Song Renzong, the prince in "Tanuki for the Prince", is famous for his frugality. Of course, there is a difference of 108,000 miles between "Tanuki for the Prince" and the official history, so I won't go into details.

"It's not covered, it's shaved head, and there are injuries, but it's not obvious, it's really pleasing to the eye!" Xie Zhihao sighed.

"Okay, you've sold it all, sigh what's the matter! Let's go, since you're here, let's take a look!"

Xie Zhihao shook his head, "There is nothing too brilliant in the porcelain, and there is also a Jiaqing 'furoshiki' that is good, but the starting price is too high." ”
