Xu Jianmin was very satisfied with Yang Jing's praise, but when he saw the four pieces of jade rough materials that Yang Jing brought over, his brows were tightly knitted together.
"Are you sure that these things you bought are raw jade? Not stone eggs mined from a quarry? Man, don't be fooled by Lao Zhao from Baoyuzhai. That guy is not a good person."
Sixteen or seventeen years ago, Xu Jianmin and his uncle teamed up to gamble on jadeite stones, but they both lost everything. Jianmin's wife almost divorced him because of this. Of course he knew how to recognize rough jadeite.
Yang Jing said with a smile: "Uncle Jianmin, I was just joking. I felt that these pieces of material were good, so I bought them. These materials are all old pit materials from Nanqi field. Although they are a bit small, who knows what is inside? Maybe I will be lucky and there will be good things inside."
Xu Jianmin sighed, turned his head and said to his uncle who was installing a grinding wheel on an angle grinder, "Xiaolong, you don't care about your nephew. Even if these pieces of material are worthless, they must be worth 20,000 or 30,000 per kilogram, right? These must be worth 100,000 yuan, right?"
As he tightened the screws, my uncle said with a smile, "Jianmin, don't worry about that kid. He's grown up now, and a few hundred thousand dollars is nothing to him. Before he came back from England, he bought three Picasso sketches, and sold them for more than two million pounds. Now he's an absolute multimillionaire. We two brothers can't compete with him."
Xu Jianmin was shocked. "Damn, did you really find three Picasso sketches?"
Yang Jing nodded with a smile, and then while changing his clothes, he told him the story of how he found the three sketches, which shocked the burly Chinese man.
Xu Jianmin had extra work clothes, and Yang Jing was wearing an Armani suit. He couldn't wear clothes worth more than 60,000 yuan to cut the stone, right? If so, after these four pieces of material were cut, he would have to throw away his clothes.
Seeing that Yang Jing really wanted to solve the stone by himself, Xu Jianmin quickly changed his clothes and handed Yang Jing an anti-smog mask and plexiglass goggles. "Can you solve this thing?"
Yang Jing shook his head and said, "Uncle Jianmin, I have never cut rough materials before. I just watched others cut them a few times. But today these pieces of material are very small, so I don't need a stone cutter. I can just use an angle grinder to grind them. It shouldn't be difficult."
Xu Jianmin gave Yang Jing a thumbs-up gesture and said with a smile, "You are really a young and inexperienced person who is not afraid of tigers! Okay, you come and polish the stone, and I'll help you."
"Haha, then I'll trouble Uncle Jianmin."
Xu Jianmin smiled and waved his hand, then turned to his uncle and said, "Xiaolong, why don't you come over and wipe it?"
The uncle smiled and shook his head, plugged in the power to the angle grinder, turned on the switch and tried it, then handed the angle grinder to Yang Jing and said, "I swore that I would never touch this thing again, so I'm just taking a look today."
Xu Jianmin said happily: "You are handing over the banner to your nephew! There will be successors!"
Yang Jing first placed the potato-sized piece of material on the workbench and clamped it, then said, "Uncle Jianmin, I'm not a successor. You two lost everything when you gambled on stones, and I don't want to be your successor. If I play this, I'm sure I'll make money."
Xu Jianmin made an unconvinced "tsk" sound and moved the clamped material with his hands. He found that it was not clamped very tightly, so he personally tightened the screws on the clamp and said, "This thing must be clamped tightly, otherwise it will be dangerous."
This kind of potato-sized material cannot be directly held by hand and put into the angle grinder. The angle grinder has strong force when it is turned on. It is not easy to hold such small materials. If you are not careful, the high-speed rotating grinding wheel of the angle grinder will hurt your hand.
When wiping this kind of small material, it must be clamped on the clip.
Xu Jianmin picked up the fan over there. It was an industrial electric fan that used a 380-volt power supply. After being connected to the power supply, the three blades rotated at high speed, generating strong wind force.
Then he pulled down the huge funnel, and the direction of the fan was facing the funnel mouth. After turning on the switch of the vacuum cleaner, the fan blew on this side and the funnel sucked on the other side, and there was basically no dust in the room.
There is no other way. To cut stones in such a closed workshop, you need these things. Otherwise, the dust alone can choke people to death after cutting stones for dozens of minutes or even hours.
After all the preparations were done, Yang Jing put on protective glasses and an anti-smog mask, then turned on the power of the angle grinder and began to rub the rough material.
As soon as the high-speed rotating grinding wheel touched the surface of the raw material, a series of sparks burst out immediately, and the harsh noise made Yang Jing a little unbearable. Instead, the dust that appeared was immediately blown to the funnel by the strong wind from the fan, and then sucked out by the vacuum cleaner connected to the funnel.
Xu Jianmin made a stop gesture, and Yang Jing stopped the angle grinder with some confusion. Xu Jianmin smiled and said, "I forgot to put another piece of equipment on you." As he said that, he ran to a corner of the workshop, found three pairs of earplugs from the metal cabinet, handed one pair to Yang Jing and his uncle, and put on one pair himself.
It’s true that these earplugs are quite effective. At least when I use the angle grinder to grind the stone, the noise doesn’t seem so loud anymore.
Although it was Yang Jing's first time to cut stones, he had seen others do it many times before. Moreover, he had not stopped exercising in the past few years, so he still had considerable strength in his arms and wrists. Therefore, he was able to hold the angle grinder steadily by holding the handle of the angle grinder with both hands.
In fact, stone polishing is not an easy job. In comparison, stone cutting is much easier. After all, there is a stone cutter. As long as you draw the lines and fix the material, turn on the switch, and the stone cutter will do all the rest of the work.
But it is different for polishing stone. Most of the polishing is done with an angle grinder or a homemade iron brush. People hold the angle grinder and rub it hard. If you use less force, the stone skin cannot be rubbed off. If you use more force, it is difficult to stabilize the angle grinder and it is easy to scratch the jade flesh inside. It is easy to be dangerous if you are not careful. Therefore, polishing stone is the most difficult part of the stone cutting process.
To put it bluntly, stone polishing requires stability. You need to use steady force and a steady wrist, so that you can polish the rough material quickly and well.
Yang Jing's adaptability was quite strong. After controlling the angle grinder for a few minutes, he gradually mastered the force required to rub the stone and quickly stabilized.
Less than five minutes after wiping, Xu Jianmin, who was in charge of dripping water, suddenly waved his hand, signaling Yang Jing to stop.
Yang Jing quickly took away the angle grinder and turned off the switch. His uncle beside him also came over. All three of them focused their attention on the piece of rough material that had been used to create a window.
"Seeing green!" My uncle uttered these three words excitedly!
PS: I would like to thank “冰冷八度” for the reward of 100.
