Chapter 203 The Special Effect of Spirit Stone Slag
Su Jing picked out a pot of very delicate slag from the spirit stone slag. In fact, most of the soil in the slag was quite delicate. Only a few were mixed with stone and sand. On the surface, it seemed that most of them were suitable for making ceramics.
There are several major steps in making ceramics: mud training, drawing blanks, printing blanks, sharpening blanks, drying blanks, carving flowers, glazing, firing kilns, and painting. Now Su Jing is mainly just trying the first and second steps.
The so-called mud training is generally made of porcelain stone from the mining area, first crushed by hand with a hammer to the size of an egg, and then pounded into powder with a water scoop, washed to remove impurities, and precipitated into brick-like mud. piece. Then mix the mud with water, remove the slag, rub it with both 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 to the trouble of plucking porcelain stones, he just used spirit stone slag, poured in water, and started kneading, as if he was kneading dough. Gourd painting scoop.
"Mr. Su, what are you doing?" Li Guanglei and the others, who were sitting on the grass smoking a break, looked at Su Jing strangely.
"Playing with mud, have you never played?" Su Jing said, leaving everyone speechless. Who grew up in the countryside has never played with mud, but how old are you? Speaking of which, they felt that Su Jing was really not doing his job properly, he didn't go to work, and he fiddled around at home all day long, but they were not only good at making money, but also very talented, what else can you say about them?
"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, and now he is helping to reinforce the first floor with titanium alloy plates. He is someone Su Jing can trust. Su Jing remembered that his name was Guangjia Hao.
"You see it, do you think this mud is suitable for ceramics?" Su Jing asked.
"On the surface, it looks very white and delicate, and it seems to be okay, but some mud bursts as soon as it is fired, so before the kiln is fired, it is not certain that kaolin is more suitable for ceramics. What kind of soil is this?" Guangjia Hao asked.
"I'm... just messing around with it." Su Jing said.
"If you want to play around with it yourself, you should buy kaolin clay. It is very cheap for you. The ceramics made from kaolin will be very white, delicate and flawless." Guangjia Hao laughed.
"I'll just do it, try it first and see if it will work." Su Jing said, he had heard of kaolin, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Delicate, also known as dolomite.
In addition, kaolin, also known as Guanyin soil, specifically refers to the soil that the poor used to eat to survive in the old society and the three-year difficult period, when the poor were not able to meet the green and yellow or during the famine years. Hungry people steamed kaolin clay into fake buns, which looked soft and white, very similar to real buns, to satisfy their hunger. However, "Guanyin soil" cannot be digested and absorbed by the human body. A small amount of it will not be fatal, but it will cause abdominal distension and make it difficult to defecate. Because it has no nutrition and cannot be digested, most people who are hungry will still die after eating it. During the famine years, because of eating kaolin, the abdominal distension was like a drum, and it was impossible to defecate. Countless people died of suffocation.
Compared with kaolin, the mineral of spirit stone is obviously not white enough and not 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, the inside is more important.
"You are too boring, let me help you." Seeing Su Jing rubbing wrongly, Guangjia Hao was very careful not to get his clothes dirty, so he rolled up his sleeves and came over to help Su Jing rubbed the mud. He rubbed more casually, and he didn't care if the mud splashed 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. In fact, he was very careful. In addition to being afraid of getting his clothes dirty, the main thing was that he didn't want to waste spirit stone slag, but he couldn't refuse Guang Jiahao's kindness. By him.
Guangjia Hao didn't know whether he had made ceramics or kneaded dough, or that kneading mud was similar to making cement. In short, he was very efficient, and quickly kneaded the Lingshi slag evenly and delicately, like dough.
"Okay, but you don't have a reel car, how do you pull it?" Guangjia Hao asked. After practicing the mud, the second step is to pull the plinth, which is to throw the mud ball on the center of the turntable of the reel car, and follow the steps. The general appearance of the green body is drawn by the flexion and extension of the technique.
"I'll just do whatever I say." Su Jing said, and then, under the stunned gazes of Guangjiahao, Li Guanglei and others, Su Jing called Ah Da and Ah Er and asked them to turn the basin, while Su Jing began to pull the blank. . Of course, the circle of Ah Da Ah Er was not round, the speed was not uniform, and there were problems with Su Jing's technique, so the thing that came out was naturally crooked, and it was difficult to come up with a bowl-like shape. However, it can be seen that this Lingshi slag is suitable for drawing billets, and it is not a problem to make it into a ceramic shape. It mainly depends on whether there is any problem with the kiln.
"It's almost time to rest, let's start working." Li Guanglei looked at his watch, then extinguished the cigarette butt, stood up and said, he didn't continue watching Su Jing, but he didn't have so much free time.
"Let's go." Guangjia Hao also stood up.
"I've finished smoking this cigarette." Several people were greedy for a little rest time, and were reluctant to stand up. The construction workers are sometimes so hard-working. It is 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 have to go back to work after smoking.
"Hey, why doesn't my finger hurt at all?" Guang Jiahao, who was carrying a titanium alloy plate, suddenly asked in surprise.
"Didn't you say you went to see a doctor, did you get cured?" Li Guanglei said.
"The doctor said it was rheumatoid arthritis. How could it be so easy to cure? The medicine prescribed was only for relief. In the morning, there was still a dull pain, especially when moving things. Why is there no pain at all now?" Guangjia Hao put down Titanium alloy plate, kneading my fingers, I found that some parts were still a little painful when kneaded, but it was obviously better. For Guangjia Hao, who has to support his family and his children to go to school, even if his fingers hurt, even if he has arthritis, he still has to work, as long as the pain is not too severe.
"Probably the effect of the medicine is working, but you are not happy if you don't feel pain?" Li Guanglei laughed.
"Haha, of course it's a good thing not to be in pain." Guang Jiahao just felt that it was a bit strange that the pain suddenly disappeared, of course it wasn't that he really didn't like the recovery of his fingers, he replied with a smile, and then he 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 slightly Yiliang, Guangjia Hao rubbed the mud just now, could this spirit stone slag still have the effect of curing arthritis?
