Wu Duo looked at this rosewood box, and couldn't help but say, this Luo Yuze is enough for the next book, if the things in it are not good, it really makes people have the idea of buying and returning the pearls.

Luo Yuze opened the rosewood box, and there was a big bowl here.

The caliber is about 25 centimeters, the height is about 15 centimeters, the white glaze is slightly yellow, there are carved flowers in the bowl, the mandarin duck water grass pattern, the layout is reasonable, and the decoration is smooth.

The mouth of this large bowl is inlaid with a circle of copper.

This is a typical fixed kiln.

Time is tight and the task is heavy, and while Wu grabbed the bottom, he listened directly.

The bottom is glazed and there is no lettering.

Among the five famous kilns of the Song Dynasty (Ruguan Ge Junding), the Ding kiln is the most special, and it is a bit incompatible with the other four.

As far as it itself is white porcelain, the other four are mainly celadons; as far as it likes to be carved, the other four basically do not use the knife; it appeared at least in the early Northern Song Dynasty, and the other four appeared in the late period.

There are official kilns and kilns, and there are also private kilns. In fact, the Song Dynasty did not have a clear and strict official kiln system like the Ming and Qing dynasties, and the so-called official kiln was probably similar to the official customization.

At the bottom of some of the kilns, the word "official" will be engraved, and such kilns can obviously be included in the category of official kilns.

Luo Yuze's big bowl is not engraved.

However, if you don't engrave, it doesn't necessarily mean that it is not an official customization, and you mainly have to look at the quality of the tire glaze process and so on.

After Wu Duo understood clearly, he put it down lightly and motioned for Ning Shuang to come and see.

Unexpectedly, Ning Shuang actually stretched out the middle finger of her left hand!

It's just that she is different from Wu Duo, she flicked the middle finger of her left hand on the wall of the bowl.

Finger power?

Wu Duo suddenly felt like laughing, but he couldn't say why.

Ning Shuang then picked up the bowl, looked at it in detail, and put it down after reading it.

"It's not early, and there are a lot of people, so the two masters hurry up!" Luo Yuze spoke.

"The inlay is wrong. Again, the two spoke in unison.

"No, why do you two have such a tacit understanding?" Luo Yuze looked at Ning Shuang, "You are sister, you say it first." ”

The inlay they said was naturally a circle of copper inlaid on the mouth of this bowl.

The reason why the mouth is inlaid is because the original mouth edge is exposed, and there is a "mang".

Before the middle of the Northern Song Dynasty, the kiln was being fired, that is, after the bowl was done, the bowl mouth was turned up and put into the kiln to burn. In this way, the soles of the laps will be exposed.

However, in the middle of the Northern Song Dynasty, the kiln changed to a firing method, called overburning, that is, the mouth of the bowl was facing downwards and the buckle was burned. If so, the bowl will have a ring of exposed tires.

This circle of exposed tires is rough and a little prickly, and some people call it "mang".

There are mangs in the circle foot and mangs in the mouth of the bowl, each with its own advantages and disadvantages. The bowl has a mang, which is easy to wear and tear the table when used, and the bowl has a mang, which is easy to cut the mouth if it is used to eat and drink soup.

It's not perfect.

Therefore, Song Huizong thought that "the fixed vessel is unusable", and he did not like white porcelain, so he personally presided over the Ru kiln, which was a nail burning, basically not exposed, only a few small sesame fetal points appeared at the bottom.

I like the white porcelain of the kiln, and I want to solve the problem of the open tire of the bowl, so there is an inlay.

In the Song Dynasty, there were mainly two kinds of gold and copper. There are also inlaid with silver, but there are few, because the kiln is white porcelain, and the inlaid silver mouth is a little smooth, not so good-looking.

Chrysostom was a bit extravagant, either the royal family did it, or the rich were doing it for show.

Copper mouths are the most common. The copper mouth is also divided into grades, and the best one is naturally copper.

Since Luo Yuze ordered Ning Shuang, Ning Shuang responded, "Your copper inlay is not from the Song Dynasty, but from the Republic of China." ”

When Luo Yuze heard this, he looked at Wu Duo again, Wu Duo nodded, "The Republic of China is old, but this is a first-class craft, and it should be done by the masters back then." ”

The kiln ware that has been handed down from generation to generation must be more valuable than the one that is not inlaid.

During the period of the Republic of China, more attention was paid to the old kiln, and after the kiln bowl was determined, if there was no inlay, it would often be added with an inlay, and then it would be old.

Luo Yuze arched his hand towards Ning Shuang, "Sister, tell me about it." ”

Ning Shuang nodded, "This inlay process is not very difficult, many craftsmen can do it finely, the key is to make it old." As far as I know, there are two main ways to make the copper inlay of the Ding kiln of the Republic of China old, one is to polish it with charcoal and then smear it with sesame oil, and then blow it with fire, so that there will be a maroon effect. There is also the use of silver nitrate, which has the effect of black and then dark green. ”

"My big bowl is maroon-colored, do you mean the first method?"

"Yes. But after all, it is not as natural as the real old inlay, especially in the uneven blowing of individual places. Ning Shuang nodded.

"I said, sister, you are an archaeology person, why are you so familiar with old-fashioned?"

Ning Shuang smiled but said nothing.

"Brother, do you have an opinion with her?" Luo Yuze asked Wu Duo again.

Wu Duo groaned, "If only your bowl were Chrysostom." ”

"I don't know that? Of course, Chrysostom is more expensive. Luo Yuze was a little depressed.

Ning Shuang explained, "What he means is that most of the Dingyao bowls with inlaid mouths on the market are old in the Republic of China, while Chrysostom is difficult to make old, and it is often the old inlaid mouth of the Song Dynasty." ”

"Hey, you two are really good, one says, the other notes!" Luo Yuze spread his hands, "The price difference between the old inlay in the Song Dynasty and the inlay in the Republic of China is quite a lot." ”

"Be content, I think the bowl itself should be fine. Ning Shuang got up, "Okay, Brother Luo, I'll see the things for you, please don't call me sister in the future." ”

"Well, the big head is still on the bowl. Luo Yuze muttered, but looked at Wu Duo again as if he was not at ease, "Brother, are you sure that the bowl itself is fine?"

"This ······" Wu Duo frowned.

Seeing Wu Duo like this, Ning Shuang couldn't help but stand still. Luo Yuze was anxious, "When is it, you say it now, it's better than letting me be embarrassed in front of those old men!"

"Well, my eyesight may not be accurate, but it only represents my personal opinion. Wu Duo nodded, "Brother Luo, in my opinion, your bowl can't reach the Song Dynasty, it should also be from the Republic of China." ”

"What?!" Luo Yuze almost didn't jump up.

"Less than a generation?" Ning Shuangxiu frowned slightly, "The glaze and engraving are fine, and I flicked it with my middle finger, and there is the sound of bell chime, which means that the fetal bone is also no problem." ”

Wu Duo said darkly, your middle finger and my middle finger······ Well, the usage and effect are not the same.

However, if you really let Wu Duo say one, two, three, four, it will be difficult for him. Because he couldn't see what was wrong, he only knew that the bowl and the inlay were from the Republic of China, that is, this was a complete imitation of the Northern Song Dynasty kiln of the Republic of China.

Perhaps, the flaws can only be found from the mouth of the bowl of the exposed tire, and the high-imitation craftsmen at that time may have added copper inlays to cover up the flaws. Wu Duo can only say this.
