Su Jing picked a pot of particularly delicate ones from the spirit stone slag, in fact, most of the soil in the slag is quite delicate, only a few are mixed with stone and sand, and on the surface, most of them seem to be quite suitable for making ceramics.

There are several major steps in making ceramics: mud training, blank drawing, printing blank, blank, blank, blank, carving, glazing, kiln firing, painting, and now Su Jing is mainly just trying the first and second steps.

The so-called mud refining is generally taken from the mining area to take porcelain stone, first manually crushed with an iron hammer to the size of an egg, and then used water to beat into powder, washed, remove impurities, and precipitated to make brick-like mud. Then mix the mud with water, remove the slag, rub it with your hands, or step on it with your feet, squeeze out the air in the mud, and make the moisture in the mud even.

Su Jing didn't have to go to the trouble of quarrying porcelain stones, he directly used the spirit stone slag, poured water, and then began to knead, as if kneading the dough, of course, Su Jing had never kneaded the dough, so he could only draw a scoop according to what he saw on TV.

"Mr. Su, what are you doing?" Li Guanglei and the others, who were sitting on the grass smoking and resting, looked at Su Jing strangely.

"Playing with mud, haven't you played?" Su Jing said, making everyone speechless for a while, who grew up in the countryside has never played with mud, but how old are you? Speaking of which, they feel that Su Jing is really a bit unprofessional, doesn't go to work, and tinkers with this and that at home all day long, but people not only make money, but also are very talented, what else can you say?

"Do you want to make ceramics?" After looking at it for a while, a particularly burly man asked, he was there when he first built the building, and now he is helping to reinforce the first floor with titanium alloy plates, he is a person that Su Jing is more trustworthy, Su Jing remembers that his name is Guangjiahao.

"You can see it, do you think this mud is suitable for making ceramics?" asked Su Jing.

"On the face of it. It's very white and delicate, and it seems to be okay, but some mud bursts as soon as it is burned, so before firing the kiln, it is not certain that it is kaolin that is more suitable for ceramics. What kind of soil are you?" asked Guang Jiahao.

"I'm ...... Dirt casually. Su Jing said.

"If you want to make your own tea, it's better to buy kaolin, it's very cheap for you, and the ceramics fired from kaolin will be very white and delicate, flawless. Guang Jiahao said with a smile.

"I'll just do it, try it first, and then talk about it. Su Jing said he had heard of kaolin, which is a type of clay and clay rock dominated by kaolinite clay minerals. Because it is white and delicate, it is also called dolomites.

In addition, kaolin, also known as Guanyin soil, refers to the soil that was eaten by the poor in the old society and the three-year difficult period, when the green and yellow were not in turn or during the famine. Hungry people use kaolin to steam into fake steamed buns, which look soft and white, much like real buns. Satisfy your hunger. However, "Guanyin soil" cannot be digested and absorbed by the human body, and eating a small amount will not be fatal. But it will be bloated, it will be difficult to defecate, and because there is no nutrition, it cannot be digested, and the vast majority of people who are hungry will still die after eating. During the famine years, he was bloated and unable to defecate due to eating kaolin. Countless people have been suffocated to death.

Compared with kaolin, the spirit stone mineral is obviously not white enough and delicate enough, even if it can be fired, I am afraid that the quality will be much worse, but Su Jing doesn't care about the surface. Intrinsic is more important.

"You're too tired of rubbing, I'll help you. Seeing Su Jing rubbing back and forth, he was careful for fear of soiling his clothes, so he rolled up his sleeves and walked over to help Su Jing rub the mud. He rubbed it much more casually, and he didn't care about the mud splashing on his clothes, of course, he had been working for a long time, and his clothes were already dirty.

Su Jing had to get out of the way a little, in fact, he was cautious, in addition to being afraid of soiling his clothes, the main thing was that he didn't want to waste the spirit stone slag, but it was not good to refuse Guang Jiahao's kindness, and besides, he didn't splash much, so he left it to him.

Guang Jiahao didn't know whether he had made ceramics or kneaded dough, or that kneading mud was similar to cement, in short, he was extremely efficient, and soon kneaded the spirit stone slag evenly and delicately, like dough.

"Okay, but you don't have a roller car, how can you pull the blank?" Guang Jiahao asked, after practicing the mud, the second step is to pull the blank, that is, throw the mud ball in the center of the wheel car, and pull out the general appearance of the blank body with the flexion and extension of the hand.

"I'll do whatever I say. Su Jing said, and then under the stunned gaze of Guangjiahao, Li Guanglei and others, Su Jing called Ah Da and Ah Er and asked them to drive the basin to rotate, and Su Jing began to pull the blank. Of course, Ah Da Ah Er's circle is not round, the speed is uneven, and Su Jing's technique is also problematic, so the things that come out are naturally crooked, and it is not easy to make a shape similar to a bowl. However, it can be seen that this spirit stone slag is suitable for drawing blanks, and it is not a problem to make a ceramic shape, mainly depending on whether there is a problem with the kiln.

"I'm almost done, let's get to work. Li Guanglei looked at his watch, then snuffed out the cigarette butt, stood up and said, he didn't continue to watch Su Jing continue, but he didn't have so much free time.

"Let's go. Guang Jiahao also stood up.

"I'm done with this cigarette. "A few people are a little greedy for little rest time, reluctant to stand up, construction workers are sometimes so hard, squeeze out some time to sit down and smoke a cigarette, it is very enjoyable. However, I still have a family to support, so I still have to go back to work after smoking.

"Hey, why don't my fingers hurt at all?" Guang Jiahao, who was lifting a titanium alloy plate, suddenly said in surprise.

"Didn't you say you went to the doctor and was cured?" Li Guanglei said.

"The doctor said that this is rheumatoid arthritis, how can it be so easy to cure, and the medicine prescribed is only for relief, and there is a faint pain in the morning, especially when moving things, why is it not painful at all now?" For Guang Jiahao, who has to support his family and provide for his children to go to school, even if his fingers hurt or even if he has arthritis, he still has to work, as long as the pain is not too bad.

"Probably because the medicine is working, are you unhappy if it doesn't hurt?" Li Guanglei said with a smile.

"Hehe, of course it's good that it doesn't hurt. Guang Jiahao just felt a little strange that it suddenly didn't hurt, naturally he didn't really like finger rehabilitation, replied with a smile, and then didn't care too much.

Su Jing, who heard this conversation not far away, was moved in his heart, thinking that Guang Jiahao's arthritis could not be cured for no reason, there must be a reason, he looked down at the soil in the basin, his eyes lit up slightly, just now Guang Jiahao rubbed the mud, could it be that this spirit stone slag still has the effect of treating arthritis? )
