Most of the modern imitations are simply added to the domestic blue and white materials, and the iron oxide powder is not calcined at high temperature, so the iron oxide cannot be evenly fused in the cobalt oxide.

Under the action of high temperature, these iron oxides will quickly float to the surface of the glaze to form crystals, and under the microscope, they are mostly slag-like spots.

"We appraisers identify a thing, as long as we grasp the key points, don't you think what you are doing here now is useless?" Ming Chenghai was already a little disdainful of Han Peacock, but now he is even more unhappy when he looks like a master, so he is not so polite when he speaks.

Hearing Ming Chenghai's reprimand, Han Peacock was not a little unhappy, he stood up directly and bowed to Ming Chenghai: "Professor Ming, the younger generation is only a shallow learner, and I really don't see the flaws in this blue and white jar, so it is better to ask Professor Ming for advice."

Of course, if you take Nezha to make trouble in the sea, you will be exempted, there is no problem with this picture at all, even if there is contempt for imperial power in it, but because of this, it cannot be denied that this is Yuan Qinghua.

After all, this picture, the painting is decent, especially those dragons, all have a distinct Yuan Dynasty atmosphere, if you don't use this reason to deny this porcelain, I really don't know, what is wrong with this porcelain. ”

Han Peacock looked at Ming Chenghai and waited for his answer.

Ming Chenghai sat there, not knowing what to say, he really had such a reason, which was also the point of what he just said.

Now that this reason has been blocked, Ming Chenghai has only appeared, and he has not seriously looked for other omissions in this porcelain. It can even be said that he did not seriously appraise this porcelain.

If this is really a fake. It is impossible not to leave a little flaw.

"If Professor Ming didn't make a serious appraisal, he can come to the stage now and make a serious appraisal again." Han Peacock really knew these old guys too well, and when he looked at it, he knew that Ming Chenghai had denied this porcelain just because of the pattern on the big jar, and he definitely didn't look at anything else.

Fortunately, this Ming Chenghai is still a bit of a senior, and he is not ashamed. walked directly to Han Peacock's side, put on gloves, and began to identify it seriously.

Qin Dake said: "Although this porcelain looks good, its pattern is an unavoidable problem. ”

"That is, Nezha is in the sea, in the ancient feudal society. Which official kiln potter would dare to fire such porcelain? "Shu is humane.

Several other experts also nodded in affirmation, and Han Peacock smiled: "There was a Qing Daoguang period, and I remember a Qing Daoguang style with blue and white inside and gold on the outside. ”

Qin Dake said with a smile: "We have all seen the picture of that picture bowl, although it is also a small bowl fired with the theme of Nezha and the sea, but the pattern on it does not involve a dragon at all. So, that's completely different from this one. ”

Han Peacock said with a smile: "Seniors, although Nezha is contemptuous of the majesty of the Son of Heaven, this picture itself is no problem, what you are entangled with is only." Does anyone dare to fire such a piece of porcelain?

Actually, that's a good confirmation, and now you've seen it. Therefore, as long as there are no omissions in other parts of this porcelain, it means that someone dared to fire such a piece of porcelain at that time. ”

"This is not right, as long as there is one error, it is enough to show that this porcelain is wrong, so everything else is a minutia." Shu Weimin directly pointed out Han Peacock's mistake.

Han Peacock said: "What if your argument itself is wrong? ”

"How is it wrong? Even if I'm not an expert in porcelain, I know that Yuan Qinghua doesn't need Su Ma to leave the green material at all, and this porcelain uses Su Ma to leave the green material, right? Shu Weimin looked at Han Peacock provocatively, even if he was not an expert in this area, he was more far-reaching than Han Peacock.

This blue and white jar, looking at the color, the blue of the whole jar is intense, with silver-black crystal spots, which is a typical Su Ma Li green material, so Shu Weimin is not wrong at this point.

However, Han Peacock immediately smiled when he saw the green material used in this big can.

Of course, when he saw such a bright blue and white material for the first time, Han Peacock also felt that his eggs hurt, but then he was a little happy.

Seeing that Han Peacock didn't speak, Shu Weimin was even more proud: "Why, didn't you just say that the arguments of several old experts are wrong?" Now what else do you want to say? ”

Han Peacock looked at the nervous Sun Xi and said: "Don't be nervous, I don't need you to answer this time, since it is a test for me, then I will say some of my own opinions, we all know that the identification or identification of blue and white porcelain in various periods of Jingde Town's history, the understanding of green materials is very important."

Su Ma Liqing is also called Suni Boqing, is the late Yuan Dynasty and early Ming Dynasty Jingdezhen blue and white porcelain special material, with Su Ma from the blue and white porcelain painted by the blue and white porcelain, blue and bright, there are silver-black crystal spots, and there will be a halo phenomenon, this reason is that Su material has high iron content, low manganese content, and domestic green material has obvious differences, which I believe no one will be wrong.

It is easy to answer the remaining questions of Su Ma Liqing at this time, the blue and white porcelain of the Yuan Dynasty and the early Ming Dynasty, most of the imported Su Ma Liqing as the green material, and form its unique style, and understand the color and main characteristics of Su Ma Liqing, which is undoubtedly of great benefit to the identification of blue and white porcelain in the above historical period.

There are four main periods in the history of Jingde Town, one is the late Yuan Dynasty, the second is the Ming Hongwu period, the third is the Ming Yongle and Xuande periods, and the fourth is the Ming orthodoxy, Jingtai and Tianshun periods, and the history of ceramics calls it the "blank period".

Due to the different firing processes and different fire conditions, there are obvious differences in the "seqin" condition of Su Ma Liqing in various historical periods, among them, especially the blue and white porcelain in the Yongle and Xuande periods of the Ming Dynasty has the largest surviving volume and is also the most representative.

That is to say, whether it is the Ming Dynasty or the Yuan Dynasty, as long as it is determined that it is the Su Ma Liqing material used, it can be determined that the one who fired such a big pot at that time must be an official kiln, but if it is the three periods of the Ming Dynasty later, with the ruthlessness of the emperors of the Zhu family, no one dares to do this without thinking about it, and there is no need for people in that period to do this.

No one in the Ming Dynasty dared to do this, so did anyone dare to do it in the Yuan Dynasty? Obviously, in the heyday of the Yuan Dynasty, no one would have dared to do this.

This can also be seen from the green material, because before the end of the Yuan Dynasty, the manufacture of Yuan blue and white did not use the "Su Ma Liqing" pigment, so that only in the late Yuan Dynasty, there was a possibility of such a Nezha naonautical chart jar.

At the end of the Yuan Dynasty, there was Su Ma Liqing material, and it is precisely because of this that it is enough to show that this is a product of the end of the Yuan Dynasty, not other periods, since it is the end of the Yuan Dynasty, why did the potters at that time dare not fire such a piece of porcelain?

At that time, the potters must have had a reason to fire such a piece of porcelain, because the Mongolian emperor at that time had already caused the people's grievances to boil and the world was in chaos, it can be said that at that time it was a change of people's minds, and many people were eager to overthrow the rule of Yuan and Mongolia. ”

It was because Han Peacock found enough reasons for Nezha to save the sea that Han Peacock looked at the other tables of this porcelain, but that was only Han Peacock out of prudence, even if he didn't look at it, he knew that his judgment was definitely right.

This big jar is certainly no problem in other aspects, otherwise it would not have come here, and there would be controversy.

Han Peacock's words, Ming Chenghai naturally heard it, he listened to it while looking at this porcelain, the green material, the painting workmanship, and the glaze color, there was no problem, which made him feel a little cold in his heart, maybe this old face will be brilliant today.

At this time, Qin Dake said: "These reasons of yours are not very tenable, although the end of the Yuan Dynasty did give Nezha a chance to survive on the subject of the sea, but even if there was a market for this porcelain at that time, what about later?" In any later dynasty, it is possible for the owner of this porcelain to be punished by the nine clans, and in the face of such a great danger, how many people dare to pass it on? ”

Han Peacock said: "I have a reason for this, say it and let the seniors evaluate one or two, you look at these dragons, especially this dragon, the dragon back, open mouth and tongue, with long horns, mane slightly floating back, thin neck and three claws, armor, elbow hair using double outline method, three different items, one up, back fins, body decorated with oblique checkered scales, neck and back out of streamers, between the ground with cloud patterns.

This is the characteristic of the typical dragon shape of the Yuan Dynasty, the dragon pattern of the Qin and Han dynasties, mostly in the shape of a beast, with complete limbs and claws, but no scale armor, often painted in a walking shape, giving people a feeling of ethereal.

The dragon pattern of the Yuan Dynasty is more fluid and flexible, the head is smaller, but the weather is broad and grand, full of spirit, the dragon pattern of the Ming Dynasty is thick and powerful, the dragon's mouth is open or closed, and the elbow hair is rich in decoration, but sometimes the shape is large and out of balance.

The dragon pattern after Qianlong and Jiaqing in the Qing Dynasty has become old-fashioned, and the image is more bloated and grotesque.

After all, as long as you are knowledgeable, you can see that this is a Yuan dragon, combined with the social situation at the time, if the descendants of the Zhu family saw such a porcelain, which means that it represents the slaughter of the emperor of the Yuan Dynasty, will the emperor of later generations keep it? ”

"If you were the emperor, would you keep such a piece of porcelain? Moreover, how many emperors do you think know the difference between the Yuan Dragon and the dragons of his own dynasty? How can such a piece of porcelain be handed down? "Shu is humane.

Han Peacock said: "This is very easy to recognize, because the dragon on this porcelain, especially the one I just said, is exactly the same as the dragon on the dragon robe of the emperor of the Yuan Dynasty, if you are not even familiar with the dragon robe you wear every day, then this emperor is mediocre enough." ”

"In any case, the possibility of such a piece of porcelain being passed down is very small, and there is a great risk, as long as it is a feudal monarchy, no emperor wants to see someone collect it, if this is a blue and white that has just been unearthed, it is possible for him to be preserved for thousands of years, but it is a heirloom, then it is impossible." Shu is a civilian.

Han Peacock looked at everyone's expressions, although Qin Dake didn't speak, they obviously agreed with Shu Weimin's reasons.
