Su Jing picked out a pot of particularly fine soil from the Lingshi slag. In fact, most of the soil in the slag was quite fine, with only a few mixed with stones and sand. On the surface, it seemed that most of it was suitable for making ceramics.
There are several main steps in making ceramics: clay making, drawing, printing, sharpening, drying, engraving, glazing, kiln firing, and painting. Now Su Jing is mainly trying the first and second steps.
The so-called mud training generally involves taking porcelain stones from mining areas, manually crushing them into egg-sized pieces with a hammer, and then pounding them into powder with a water hammer. They are then washed to remove impurities and precipitated to make brick-shaped mud. piece. Then mix the mud with water to remove the residue, rub it with your hands, or step on it with your feet to squeeze out the air in the mud and make the water in the mud even.
Su Jing didn't have to go through the trouble of mining porcelain stone. She directly used Lingshi slag, poured water into it, and then started kneading it like dough. Of course, Su Jing had never kneaded the dough, so she could only make it based on what she saw on TV. A gourd and a gourd.
"Mr. Su, what are you doing?" Li Guanglei and others, who were sitting on the grass smoking and taking a break, looked at Su Jing strangely.
"Have you never played with mud before?" Su Jing said, leaving everyone speechless for a while. Whoever 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 not doing her job properly. She doesn't go to work and spends all day doing things at home. But she is not only good at making money, but also very talented. What else can you say about her
"Do you want to make ceramics?" After watching for a while, a particularly burly man asked. He was there when the building was first built. Now he is helping to reinforce the first floor with titanium alloy plates. He is someone Su Jing trusts. Su Jing remembered that his name was Guang Jiahao.
"You saw it, do you think this mud is suitable for making ceramics?" Su Jing asked.
"On the surface, it seems to be quite white and delicate, which seems to be okay. However, some clay will explode as soon as it is fired. So before firing the kiln, we cannot say for sure. Kaolin clay is more suitable for ceramics. What kind of clay is this?" Guang Jiahao asked.
"I'm... just a fool to do whatever I want." Su Jing said.
"If you want to tinker with it yourself, you'd better buy kaolin clay. It's very cheap for you. Only the ceramics made from kaolin clay will be very white, delicate and flawless." Guangjia Hao said with a smile.
"I'll just do it casually and try it first to see if it works." Su Jing said. He had heard of kaolin, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. It is white and Delicate, also known as dolomitic soil.
In addition, kaolin clay is also called Guanyin soil, which refers specifically to the soil that the poor ate in order to survive during the lean years or famine years in the old society and the Three Years of Difficulty Period. Hungry people steamed kaolin clay into fake steamed buns, which looked soft and white, much like real steamed buns, to satisfy their hunger. However, "Guanyin soil" cannot be digested and absorbed by the human body. Eating a small amount will not be fatal, but it will cause abdominal distension and make it difficult to defecate. Since it has no nutrition and cannot be digested, most people who are famine will still die after eating it. During the famine years, countless people suffocated to death due to their abdominal distension and inability to defecate due to eating kaolin clay.
Compared with kaolin, the mineral quality of spirit stone is obviously not white enough or delicate enough. Even if it can be fired, the quality will probably look much worse. However, Su Jing doesn't care about the appearance, the inside is more important.
"You're rubbing too hard, let me help you." Guangjia Hao saw Su Jing rubbing back and forth, being careful not to get her clothes dirty. He was very displeased, so he rolled up his sleeves and came over to help. Su Jing rubbed up the mud. He rubbed it more casually, and didn't care if mud splashed on his clothes. Of course, he had been working for a long time, and his clothes were already extremely dirty.
Su Jing had no choice but to get out of the way. In fact, he was very cautious. Apart from being afraid of soiling his clothes, the most important thing was not to waste the spirit stone slag. However, it was difficult to refuse Guang Jiahao's kindness. Besides, he couldn't spill much, so he Let him.
Guang Jiahao didn't know whether he had made ceramics or kneaded dough, or whether kneading mud was similar to making cement. In short, he was extremely efficient. He quickly kneaded the Lingshi slag evenly and finely, just like dough.
"Okay, but you don't have a pulley, how do you pull out the clay?" Guangjia Hao asked. After practicing the clay, the second step is to throw the clay ball into the center of the turntable of the pulley. The rough shape of the blank is obtained by bending, stretching, and drawing the technique.
"I told you to do whatever you want." Su Jing said, and then under the stunned gazes of Guang Jiahao, Li Guanglei and others, Su Jing called Ada and Aer and asked them to drive the basin to rotate, while Su Jing began to pull the billet. . Of course, the circles Ah Da Ah Er turned were not round and the speed was uneven, and there were also problems with Su Jing's technique, so the things that came out were naturally crooked, and it took a lot of effort to create a bowl-like shape. However, it can be seen that this Lingshi slag is suitable for drawing, and it will not be a problem to make it into a ceramic shape. It mainly depends on whether there are any problems in the kiln.
"It's almost time to rest, let's start working." Li Guanglei looked at his watch, then put out the cigarette butt, stood up and said, he did not continue to watch Su Jing go on, but he did not have so much free time.
"Let's go." Guangjia Hao also stood up.
"I'm going to finish smoking this cigarette." A few people were a little greedy for the short rest time and were reluctant to stand up. Construction workers are so hard sometimes, so it would be a good enjoyment to squeeze out some time to sit down and smoke a cigarette. 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 were you cured?" Li Guanglei said.
"The doctor said it was rheumatoid arthritis. It can't be cured so easily. The medicine prescribed only relieves the pain. It still hurts a little in the morning, especially when moving things. How come it doesn't hurt at all now?" Guang Jiahao put it down. Titanium alloy plate, kneading my fingers, I found that some parts still hurt a little when I kneaded them, but they were obviously much better. For Guang Jiahao, who has to support his family and send his children to school, he still has to work even if his fingers hurt or even have arthritis, as long as the pain is not too severe.
"Maybe it's because the medicine has taken effect, but you're not happy that it doesn't hurt anymore?" Li Guanglei said with a smile.
"Haha, of course it's a good thing that it doesn't hurt." Guang Jiahao just felt a little strange that the pain suddenly stopped. Naturally, he didn't really dislike the recovery of his finger. He replied with a smile, and then didn't pay much attention to it.
Su Jing, who heard this conversation not far away, was moved in his heart. He thought that Guang Jiahao's arthritis could not be cured for no reason. There must be a reason. He lowered his head and looked at the soil in the basin, his eyes slightly As soon as it turned on, Guangjia Hao had just rubbed the mud. Could it be that this spirit stone slag also has the effect of treating arthritis
