God-level Golden Hand

Chapter 378
Of course, Tang Xianhai did not take out such a pile of old Zhu mud from Zhaozhuang to give to Xu Jingxing, it was just for demonstration.

Anyway, it is just a demonstration, as long as it is not fired in the kiln, the vermilion mud can be crushed and reused at any time.But even so, it was really hard work for Tang Xianhai to take out this fine clay.

Tang Xianhai pointed to the mud and said, "This is mud that has passed the obsolete period. Generally speaking, old mud needs to be practiced again before it can be used. Let me show you the skills of practicing mud first."

Xu Jingxing nodded quickly. He went back to the hotel last night to check some information. He knew that the mud usually goes through two natural aging processes. Claypot and mud training, this kind of purple sand mud is often called new mud and can be used directly.

However, the craftsmen who pay more attention to it will seal the new mud for secondary aging, and after a period of aging, it will become old mud.

The old mud can't be used directly after it is taken out, and it needs to be practiced a second time, so the mud is the best to use.

The so-called kneading is actually similar to kneading noodles. There are also two ways of kneading kneading by hand and kneading by machine.

Of course, hand-made mud is an ancient and primitive choice with the best effect, but the efficiency is relatively low.

You know, the principle of hand-made mud is similar to that of kneading noodles, but it is another matter to actually do it. It is necessary to repeatedly beat, knead, and compress on the mud bench with a heavy mallet until the mud is completely mixed. Only when all the air in the tank is squeezed out can it be considered qualified.

This process is not only tiring, but also very strict. After all, it is hand-beating. If you are not careful, some tiny air bubbles will be left in the mud. Even a small air bubble may ruin a good pot.

As for machine mud refining, it is much easier. The high-tech vacuum mud refining machine can completely expel the air in the mud in a short time, and the efficiency is very high.

Moreover, the mud produced by the vacuum mud refiner also has certain advantages, such as more uniform mud structure, better plasticity and fine density.

However, the stress inside this kind of mud is very strong, because the stronger the external force you apply, the stronger the stress will be. Such a strong stress is released during high-temperature firing, which can easily cause shrinkage and deformation of the structure, so that Lower yield.

In addition, purple sand pots are not porcelain. The characteristics of purple sand pots are that the structure has pores, which can absorb water and insulate temperature. The unique moisturizing fetal quality of the organ becomes dry.

So Tang Xianhai has been practicing mud by hand, and this time is of course no exception.

Tang Xianhai cut off a large piece of mud and put it on the mud bench, and then began to beat it with a huge mallet, turning over and over while beating. The whole process seemed boring and tiring, but Tang Xianhai devoted himself to doing it.And while he was doing it, he was explaining. After doing it once, he handed the big gavel to Xu Jingxing, "You have a try."

Xu Jingxing's hands were indeed a little itchy, and he didn't think it was difficult. It seemed very simple, but it might be a little tiring to keep swinging the gavel, but the most important thing he lacked was strength.

So with great interest, he took the mallet and turned it to the front of the mud stool, and beat it down with one hand.

"puff--"

There was a muffled sound, and the mud splashed like thin mud, but the force was too strong.

Tang Xianhai was startled, almost jumped up, and hurriedly shouted: "Take it easy, are you forging?"

"Ahem, I'm sorry," Xu Jingxing scratched his head in embarrassment. He didn't expect that the mud looked solid, but it was so rough.He didn't even think about it, he was so powerful, let alone a ball of purple sand mud, even an iron ingot couldn't withstand his beating like this.

Tang Xianhai hurriedly pointed out: "Use less force, as long as you can flatten the mud, don't punch it through. If you punch it too thoroughly, the mud will lose a certain degree of plasticity."

Xu Jingxing grinned, collected the scattered mud, and then continued to beat. This time the strength he used was not great, but after a few hammers, it felt a bit awkward.Then he carefully recalled Tang Xianhai's actions and tried to imitate them, but he still couldn't get the point.

"Don't worry, take your time. The important thing is not the movement, but the mud. You should adjust your movement and strength according to the reaction of the mud. Make sure the mud is evenly stressed, from left to right, or from left to right. From right to left, all the mud must be subjected to force, yes, the slower the rhythm, the lighter the force, this is the second practice, so you don’t need to use so much force.”

Under Tang Xianhai's guidance, Xu Jingxing gradually found his sense. After all, he is also a craftsman, and his hands-on ability is much better than ordinary people.And his physical strength is really good, holding the mallet with one hand like a pile driver without stopping, and the sound of "puff puff puff" can be heard endlessly.

At the beginning, the rhythm of his beating the mud was a bit chaotic, so it sounded like noise, but after he found the rhythm, the sound became a little more pleasing to the ear, a bit similar to Tang Xianhai.

Tang Xianhai was quite worried at the beginning, fearing that Xu Jingxing would not find the feeling, because among the many students he had taught, even the most talented ones would take three to five days to get started in the mud practice.

He was worried that Xu Jingxing would not be able to learn anything because of the short time.

However, less than 10 minutes later, his mouth grew bigger and bigger. Watching the ball of mud with a somewhat stale smell glowing with new luster little by little under Xu Jingxing's hands, it was like seeing a monster.

Is this what Lao Yu said about the extraordinary talent?

Tang Xianhai thought of what Yu Zecheng said. He was a little skeptical before, but now he is a little moved, and even a little regretful. If he simply and neatly accepted Xu Jingxing as his apprentice yesterday, that would be great!
It was too late to speak now, because they had met as equals yesterday, and now when they mentioned recruiting disciples, let alone whether Xu Jingxing would agree, even if Xu Jingxing would agree, he, Tang Xianhai, would not be able to open his mouth.

Thinking of this, Tang Xianhai felt regretful.

But after regretting it, he still tried his best to teach Xu Jingxing the skills of practicing mud. Originally, he just wanted Xu Jingxing to experience the process, but it can be seen that Xu Jingxing is getting better and better, so he simply stood aside and only talked and didn't move.

When the mud became oily, moist, delicate and firm, Tang Xianhai shouted to stop, took a carving knife aside and scratched on your face, looked at the edge of the knife, and nodded with satisfaction, "Very good, very good, the first Being able to do this for the first time with mud practice is enough to prove that your hands-on ability is really strong."

Xu Jingxing quickly asked: "Old Tang, is this all right? How do you judge?"
