Hesitation is not whether to make a move, Yu Yao is not interested in this price. What he hesitates is whether it is genuine.

At this time, Yang Rui, who was beside Yu Yao, seemed to be interested in this blue and white glaze, and flicked Yu Yao's arm while looking at Yu Yao.

Yu Yao was still groaning.

If it is said that the blue and white glaze of the Qing Dynasty is red, Yongzheng is the most, especially the hair color of the red in the glaze, showing bright red, also known as "treasure burnt red". The blue and white glaze of the Kangxi period is red, and the color of the red is somewhat black. As for the blue and white glaze red in the Qianlong Dynasty, it is stronger than Kangxi and worse than Yongzheng. So although the level is not low, the characteristics are not so distinct.

Yang Rui couldn't pay attention to Yu Yao when he saw it, so he whispered, "The atmosphere is a little tight, and the price is too expensive, forget it!"

Yang Rui said that the atmosphere was because he had observed that two or three people were already eager to try this blue and white glaze red plum vase!

When Yu Yao heard this, his brows suddenly stretched, and he turned his head and whispered, "That's a good point!

"Huh?" Yang Rui was stunned, but it was not appropriate to say more at this time, since Yu Yao said that it was right to give up, then let's go back and talk about it.

Yu Yao suddenly thought of the atmosphere of porcelain firing from the atmosphere that Yang Rui said, and combined with the previous judgment, he completely understood it!

In the process of porcelain firing, atmosphere is a technical term, which refers to the firing environment in which the porcelain is fired.

To put it simply, in the process of porcelain firing, there are actually two atmospheres, oxidizing atmosphere and reducing atmosphere.

When the kiln is fired, if the fire door is opened, oxygen can enter, and the porcelain is in an oxidizing atmosphere, and if the fire door is closed, no oxygen enters, then the kiln is a reducing atmosphere.

The red in the glaze is fired in a reducing atmosphere. Moreover, copper, as a colorant, is not very stable, and the temperature is high, so it will be "restored" and gone, and it will not be red, and it will be completely scrapped. If the temperature is low, it will be black, and if it is a little lighter, it will be fine, and if it is very dark, it will have to be scrapped.

Most people may not imagine, what is the control range of this temperature?

Within 10 degrees Celsius!

You must know that the high temperature in the porcelain kiln is about 1300 degrees Celsius, and the difficulty of controlling the error of 10 degrees Celsius on this basis can be imagined.

This difficulty is what the ancient potters faced. Because it no longer exists, science and technology are developed, and the porcelain kiln is equipped with a temperature control meter, and the gas is burned, which can quickly and accurately adjust the temperature.

Therefore, the variety of glaze red has a very low yield in history and cannot be maintained for a long time. To summarize it in general, that is, from the Yuan Dynasty to the early Ming Dynasty and the Kang Yongqian period of the Qing Dynasty, these two major stages were fully burned.

Among them, Yongzheng's glaze red is the most bright red, and there is no fainting. However, even if Yongzheng glaze is red, a piece of red will not be so uniform, which is determined by the basis of the firewood kiln at that time, the temperature control error can be within 10 degrees Celsius, but it is impossible to maintain accurate stability.

And this piece of blue and white glaze red, although the color is not as bright as the red in the Yongzheng glaze, has the hair color characteristics of the Qianlong Dynasty, but the red is too uniform, although it is not completely uniform, but it has exceeded the scope of what it should be.

This must be the result of the modern porcelain kiln's use of temperature control tables to finely control the kiln temperature!

Although it is complicated to explain, it is actually only a short time in Yu Yao's mind.

For this kind of top-level imitation, with Yu Yao's eyesight, it is still in the twists and turns to understand, so it is not surprising that others are eager to try.

After the old man said "open the table", a tall and thin man blocked the demolition with his left arm and probed with his right hand, snatching the plastic card with the number and price tag in his hand. On his left and opposite side, one person each shot more decisively, but not as fast as him. In addition, there were two or three people who hesitated slightly, and they couldn't catch up with it.

In the end, all three pieces of porcelain were bought.

After two rounds, there was a pause in between. The old man actually talked about some things about blue and white and red in the glaze.

In fact, blue and white and red in the glaze are underglaze colors, that is, the color is painted on the porcelain embryo first, and then the glaze is fired, and the difference is only in the difference in materials. However, the names of the two are not unified, if the blue and white are unified, then the glaze red should be called "red flower", and if the glaze red is unified, the blue and white should be called "glaze green".

The old man was talking about such interesting things, and he would not talk about any identification tips.

This is a small episode on the flowing water seat. In fact, there was a gap after the first round, but the old man didn't speak.

Yu Yao and Yang Rui didn't listen to him, and the two exchanged words in a low voice for a while.

The things that came up in the third round later, there was no porcelain, they were all small jade pieces.

The jade plate of Hetian jade, the agate ring, the jade pipe. Jade is relatively easy to identify, and Yu Yao can see it faster.

The jade plate of Hetian jade is a thing of the Ming Dynasty, but the carving is relatively coarse, and a corner is missing.

The agate ring is from the Qing Dynasty, a little smaller than the cassock ring, the craftsmanship is good, but the texture is ordinary agate.

The best of this is the jade pipe, although it is from the late Qing Dynasty, but the water is good, and the color is apple green.

The pipe is a unique thing in the Qing Dynasty, because the official hat of the Qing Dynasty changed the shape of the wings of the previous high-crowned hat and made it look like a top hat. The feather tube, just under the top bead of the top hat, is used to place the feathers. Generally speaking, it is about the same thickness as a dry tobacco pipe, and it is about two inches long.

What kind of feathers are used, single-eyed, two-eyed, and three-eyed feathers all have corresponding grades.

And the pipe, what material is used, is also particular. A first-grade civil official, a first-grade Zhenguo Gong, and an auxiliary Guogong can use the jade feather pipe, while the first-grade military attaché, a first-grade Zhenguo general, and an auxiliary general can use a white jade feather pipe.

This jade feather tube is the real thing that opened the door.

But the price is also high, a little bit higher than the market price. Such a thing is not easy to find, and it can only rise and not fall in the future, which is calculated accurately, and there will definitely be people who are excited. As far as the money of this pipe is concerned, it is clearly earned.

Of these three things, Yu Yao and Yang Rui didn't plan to make a move.

After this round, the old man said "serve tea and snacks" and went out through the back door.

The so-called flowing water seat also has to master a rhythm, and it is impossible to keep going up, so that buyers may not be comfortable, and they may not have so many things.

When he sat down at the small round table to drink tea and eat snacks, Yang Rui told Yu Yao that this Luming Villa is a farmhouse restaurant in summer and autumn, and it can also be stayed. It is closed in winter and spring, and during this period, there are usually two antique water seats, but I heard that this year it is only open once.

The owner of Luming Villa, I heard that he used to shovel the land in a nearby village, and later practiced a stall in Panjiayuan, and after a few years, he came back to build such a Luming Villa.
