The mechanism box is divided into one to six phases according to the opening steps. There are six types of mechanism boxes. It takes 36 steps to open a camera box, 72 steps for two phases, and so on. Six phases are 2304 steps. It's hard to open a two-phase mechanism box without pithy formula.

However, even if there is a formula, the five phase and six phase mechanism boxes don't have a certain perseverance and brain, and it's not so easy to open. As for the legendary eight camera box closing, more than 9000 steps, I feel terrible when I think about it.

After identification, there are 144 steps in the formula written on the paper. The corresponding one is a three-phase mechanism box. With the mechanism box, there is even a key. It can be seen that the owner attaches great importance to the contents of the mechanism box.

Although he had the formula and key to open the mechanism box, it was useless without the mechanism box. Now Chu Chen could only expect that the mechanism box was in the original owner's home, otherwise these two things would be useless.

Next, chuchen carefully put away the note and key, and then began to restore the inkstone.

For ordinary people, it is impossible to restore the inkstone to its original appearance. However, for Chu Chen, a disciple of Liu, it is not too difficult except that it is cumbersome.

In order to increase the weight of the inkstone, Chu Chen first poured some prepared lead into the crack, and then after a series of treatment, until early in the morning, Chu Chen finally restored the inkstone to its original shape.

Looking at the almost perfect inkstone, Chu Chen nodded with satisfaction. Although there are still some small defects, as long as you use a special method to put the inkstone in the shade for a week, you can eliminate those defects, and even if you touch the water, it will not have any effect.

The next day, Chu Chen called Lao Yu, who sold him Tian Huang Yin embryo, and asked him if he was free today. If he was free, he would go to help him dismantle the belly center. Lao Yu originally planned to go out with his family today, but after receiving Chu Chen's call, Ma Shang happily agreed.

Speaking of this, Chu Chen was somewhat embarrassed. In fact, he had learned how to demolish tuzhongtang from Mr. Liu long ago, but later he forgot about it. If he hadn't thought of tuzhongtang from the organ box yesterday, he would have forgotten about it to Java.

It took chuchen half an hour to arrive at Laoyu's home in Beicheng.

The old man invited chuchen into the house, poured tea and took fruit snacks and so on. He was very enthusiastic.

After some greetings, Lao Yu took out the statue of Buddha carved with rhinoceros horn.

It's easier to open the nave, but it's not so easy to dismantle it. It took Chu Chen more than an hour to carefully take out the contents.

Because the self destruct device in the belly center hall is very dangerous, Chu Chen specially brought a container for dangerous goods. After he went back, he handed it to the professionals to handle it, and then he could finish it.

Seeing that chuchen has demolished the nave, Lao Yu is greatly relieved. Although he knows that this thing should be stable, and there won't be any problems at ordinary times, he always feels that this thing is like a time bomb, which always makes him worried. If it wasn't for chuchen's call, Lao Yu would be ready to call chuchen these days.

After finishing his business, Chu Chen planned to go home, but seeing Lao Yu's hesitation, he immediately guessed that he had something to ask him to help identify.

Anyway, after returning home, nothing happened. Chu Chen said with a smile, "Lao Yu, it's rare to come to your house. I wonder if I have the honor to appreciate your collection?"

Listen to Chu Chen say so, Lao Yu also know that Chu Chen should see his idea, which makes him more or less embarrassed, but even if Chu Chen said, he is also rare to come over once, so he quickly welcomed Chu Chen into his study.

Because he believed in Buddhism, he collected many Buddhist statues of different sizes, including ceramics, wood carvings, copper gilding and so on, which made Chu Chen feel like he had entered a small Buddhist hall.

After appreciating all kinds of Buddha statues, Lao Yu took out a plum vase and put it on his desk. With a smile on his face, he said, "Mr. Chu, this is something I mortgaged from others. I'm not very proficient in porcelain. I wonder if you can show it to me?"

"Yes Chu Chen did not refuse, very readily agreed to come down.

The plum vase is a kind of small mouth, short neck, abundant shoulder, thin bottom and round foot. Xu Zhiheng described in detail the shape, characteristics and origin of the name of the plum vase in his book yinliuzhai Shuo CI in modern times: "the mouth of the plum vase is thin and the neck is short, the shoulder is wide and broad, the tibia is narrow, the foot is slightly abundant, and the diameter of the mouth is only commensurate with the thin bone of the plum, so it is called plum vase."

At first, the plum bottle was a container for wine. Plum bottle is very beautiful, but wine storage is still its primary practical function. In order to hold more wine without losing the beauty of "my fair lady", the porcelain makers raised its largest diameter upward, which increased the capacity of holding wine without losing the beautiful image of bottle body.

The upper part of plum vase is heavy and the lower part is narrow. In this way, the center of gravity is high, and it is easy to dump in daily use. When the bottle body is skillfully made thick, it is not easy to touch the bottom of the bottle to ensure its practical function.Meiping first appeared in Tang Dynasty, and was popular in song and Liao dynasties, and many new varieties appeared. During the song and Yuan Dynasties, porcelain kilns were fired everywhere, and Jingdezhen blue and white plum vase of the Yuan Dynasty was the most exquisite.

Lao Yu is this plum vase, which is nearly 40 cm high. The overall shape of the vase is dignified and generous. It is painted with rouge glaze color to draw landscape figure patterns. People in the scene are attracted by each other. The color is bright, the enamel is moist, and the fetal body is white and delicate. Another book is "Qianlong year system of the Qing Dynasty".

Rouge, commonly known as magenta, is light rose color, bright and transparent. However, it is different from the copper red and alum red used in imperial porcelain making in the past. It is a kind of pink colored with gold and purple tone. Because the glaze contains gold, it is often called "golden red".

In fact, this method of melting gold into glaze to color was not invented by Jingdezhen porcelain workers. It was invented by Cassia of Holland in 1650. It began to be used in porcelain painting in 1680. It was not until the 21st year of Kangxi that it began to be used in Jingdezhen. At that time, it was called "Yangcai", which is also the origin of carmine.

Chu Chen looked at the vase carefully and said, "Lao Yu, you're lucky. This is really a genuine product from the Qianlong period. Let's look at the shape of the vase first. You can see that the shoulder of the vase is very plump, almost in a straight line, and it's straight below the waist. This is the typical style of Qianlong period. If you look at it again, the font is neat and elegant, the texture is white and fine, the enamel is also very moist, and the painting is also very good. It's a rare boutique. "

Old Yu was very happy to hear that this plum vase was genuine, but he was still a little puzzled, so he said, "Mr. Chu, there's one thing I can't understand. Why is the color of its carmine hair so deep and light?"

"Ha ha, the phenomenon you said was quite normal during the reign of Emperor Qianlong." Chuchen explained with a smile: "although Rouge was introduced into Jingdezhen imperial factory in the middle and early Kangxi period, it was not widely used and carried forward in the imperial factory until the Qianlong period because of its high technology content and high cost."

"However, in the Qianlong period, in order to make the glaze water rich and moist, the glaze layer on the surface of the utensils was thick, and the glaze water flowed in different degrees during the firing. Therefore, the color of the rouge water was often uneven, which was the reason why the color of the Rouge water was uneven."

"Oh, I see!" He nodded and then said with a smile, "Mr. Chu, it's almost time for dinner. Let's have dinner together?"

"Bang, bang, bang!"

Before Chu Chen responded, he heard someone knocking at the door: "Lao Yu, are you at home?"

Lao Yu apologizes to Chu Chen, and then goes out to open the door in a hurry. Seeing this, Chu Chen goes out with him.

"Lao Hu, what's the matter?" When Lao Yu opened the door, he turned out to be an old friend of his own.

"Lao Yu, let me tell you, I made a baby to open your eyes."

As he walked in, the man said as if he were offering a treasure. However, on the way, he saw Chu Chen coming out of his study and said with some embarrassment: "Lao Yu, you have guests here. I'm so sorry. I don't know if I disturb you?"

"It's OK, it's OK. I just want to see your baby, but I don't know if you mind?" Chuchen waved his hand with a smile.

Lao Yu quickly said, "Lao Hu, this is Mr. Chu Chen Chu, a senior apprentice of Mr. Liu."

"Liu Zhi and Liu Lao?" Lao Hu asked pleasantly.

After getting Lao Yu's affirmation, he said with great joy: "today is really a coincidence. I didn't expect that I met Liu Lao's Apprentice."

With that, he quickly put the things in his hand on the table, went forward to shake hands with Chu Chen, and introduced himself.

After a brief exchange, we turned our attention to the larger brocade box on the table.

Lao Hu opened the box and took out the contents carefully.

"Can with red dragon pattern in glaze?" Seeing the objects in the box, Lao Yu asked.

Lao Hu said with a smile: "Hey, yes, it's the red dragon shaped pot in glaze. Lao Yu, guess what age it was."

Lao Yu said: "just take a look. I can't tell which era it was. It's not the Yuan Dynasty, is it?"

"Ha ha!" Lao Hu said with a smile: "you really guessed right, it is the Yuan Dynasty."

"What?"

As mentioned above, the underglaze red is fired in reducing atmosphere with copper as coloring agent. If the temperature is higher or lower, it will fail immediately. If the temperature is lower, the color will turn black, very ugly. If the temperature is high, the color will be gone. Generally, the allowable difference between the high and low temperatures is only about 10 degrees. In ancient times, this temperature difference is very difficult to control. Only experienced kiln workers can see it.
