Chapter 297 Atmosphere
The hesitation is not whether to make a move, Yu Yao is not interested in this price.It is doubtful whether it is genuine or not.

At this time, Yang Rui who was beside Yu Yao also seemed to be interested in this blue and white underglaze red, he pushed Yu Yao's arm and looked at Yu Yao at the same time.

Yu Yao was still pondering.

If we talk about the blue and white underglaze red in the Qing Dynasty, Yongzheng is the most, especially the underglaze red hair color, which is bright red, and is also called "treasure burning red".In the Kangxi period, the blue and white glaze was red, and the red color was somewhat black.As for the blue and white underglaze red of the Qianlong Dynasty, it was better than Kangxi and worse than Yongzheng.So although the standard is not low, but the characteristics are not so clear.

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

Yang Rui said the atmosphere because he observed that two or three people were eager to try this red plum vase in blue and white glaze!
When Yu Yao heard this, his brows relaxed suddenly, and he turned his head and whispered, "Well said! Just give up!"

"Ah?" Yang Rui was taken aback, but it's inappropriate to say more at this time, since Yu Yao said to give up, it's right, let's talk about it later.

From what Yang Rui said about the atmosphere of the scene, Yu Yao suddenly thought of the atmosphere of porcelain firing, combined with the previous judgment, he completely understood it!
In the process of firing porcelain, atmosphere is a professional term that refers to the firing environment in which porcelain is fired.

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

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

Underglaze red is fired in a reducing atmosphere.Moreover, copper, as a coloring agent, is not very stable. If the temperature is high, the "reduction" will disappear, and the red color will not be visible, so it will be completely scrapped.If the temperature is low, it will turn black. If it is slightly dark, it is acceptable. If it is too 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. On this basis, it is difficult to control the error of 10 degrees Celsius.

This difficulty refers to what ancient kiln workers faced.Because it does not exist now, technology is advanced, there is a temperature control meter in the porcelain kiln, and the burning is gas, which can quickly and accurately adjust the temperature.

Therefore, the variety of underglaze red has a very low yield in history and cannot be maintained for a long time.To sum it up generally, that is, from the Yuan Dynasty to the early Ming Dynasty, and the Kang, Yong and Qian Dynasties of the Qing Dynasty, these two major stages were fully fired.

Among them, Yongzheng's underglaze red is the brightest red, and it does not smudge.However, even if it is Yongzheng underglaze red, it will not be so uniform in a piece of red. This is based on the wood-fired kiln at that time. The temperature control error can be within 10 degrees Celsius, but it is impossible to maintain precise stability. of.

And this blue and white underglaze red, although the color is not as bright as the Yongzheng underglaze red, and has the characteristics of the hair color of the Qianlong Dynasty, but the red is too uniform, although it is not completely uniform, but it has exceeded the proper range.

This must be the result of the fine control of the kiln temperature by the use of temperature control meters in modern porcelain kilns!

Although the explanation is more complicated, it only takes a short time in Yu Yao's mind.

As for this top-level imitation, with Yu Yao's eyesight, it was only through twists and turns that he understood it, so it's not surprising that other people are eager to try it.

After the old man said "Let's open", a tall and thin man picked and rolled with his left arm and poked with his right hand, snatching the plastic card with the serial number and price tag in his hand.On his left and on the opposite side, there was one person who shot more decisively, but neither was as fast as him.In addition, there are two or three people who are slightly hesitant, and they will not be able to catch up.

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

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

In fact, blue and white and underglaze red are both underglaze colors, which means that the porcelain embryos are painted first, then glazed, and fired once in the kiln. The only difference lies in the different materials used.But the names of the two are not unified. If they are unified according to blue and white, then underglaze red should be called "safflower"; if they are unified according to underglaze red, blue and white should be called "glaze green".

What the old man talked about was interesting things like this, and he would never talk about the key to identification.

This can be regarded as a small episode on the running water mat.In fact, there was a period of time after the first round, but the old man didn't speak.

Yu Yao and Yang Rui didn't listen to him, they exchanged in whispers for a while.

The things that came up in the third round later were all small jade pieces instead of porcelain.

Jade plaques of Hetian jade, agate rings, and jade quills.Jade articles are relatively easy to identify, and Yu Yao can see them faster.

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

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

The best thing here is the jadeite quill. Although it is from the late Qing Dynasty, it has good water quality and the color is apple green.

Lingguan is a unique thing of the Qing Dynasty, because the official hats of the Qing Dynasty changed the shape of the high crown and wings of the previous dynasty, and made them look like top hats.The feather tube, just under the top bead of the top hat, is used to place 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 is particular, and there are corresponding grades for single-eyed, double-eyed, and triple-eyed feathers.

As for the feather tube, the material used is also particular.First-rank civil servants, first-rank Dukes of Zhen Guo and Duke Fu of the State can use jade feather pipes; while military officers of the first rank, generals of Zhen Guo and General Fu Guo can use white jade feather pipes.

This emerald quill is the real thing that opens the door.

But the price is also high, a little bit higher than the market price.Such things are not easy to find, and they can only rise and never fall in the future.As far as the money of the Ling Guan is concerned, it is clearly earned.

Yu Yao and Yang Rui didn't plan to take any of these three things.

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

The so-called running water mat also needs to master a rhythm, it is impossible to keep on it, so the buyers may not be comfortable, and they may not have so many things.

When sitting at the small round table drinking tea and eating snacks, Yang Rui told Yu Yao that this Luming Villa is a farmhouse hotel in summer and autumn, and you can also stay there.It will not be opened in winter and spring. During this period, the Antique Floating Water Seat is usually opened twice, but I heard that it will only be opened this year.

The owner of Luming Mountain Villa, I heard that he used to shovel land in a nearby village, and later practiced stalls in Panjiayuan. After working for a few years, he came back to build such a Luming Mountain Villa. Maybe it’s because the business is not good when the weather is cold. It's easy to do, he actually combined his old business, came up with such an idea, and opened the antique flowing water table.
