The old man surnamed Wu put on reading glasses, sat in front of the stone dissolving machine, and looked at the rough stone in his hand repeatedly, but he couldn't make up his mind. Finally, he looked up at Ren Jiangchi who was standing aside, "Master Jiang Chi, where should you open the window from this stone?"

Ren Jiangchi groaned for a while, and then pointed to a position on the stone with his hand.

The old man surnamed Wu was a little surprised, because he chose three window positions on this rough stone, and the position that Ren Jiangchi pointed out was not among his three alternative positions.

"Master Jiang Chi, why did you choose this position?" The old man surnamed Wu had a very low posture and looked like he was asking for advice.

"Other places have thicker shells, and this place has the thinnest shells, and the effect of opening windows is the best!" Ren Jiangchi said.

"This place has the thinnest shell?" The old man surnamed Wu took out a flashlight, illuminated it at the position where Ren Jiangchi pointed, and then said: "No, this place has the lowest transparency, and it stands to reason that it should be the thickest shell." ”

Most of Ren Jiangchi's gambling experience comes from his father's classmate Rao Dongcheng, but in just a few hours, how many things can Rao Dongcheng say?

But there is one point, the place he pointed to is the thinnest skin, which is seen through with the flashlight APP, and it will never make a mistake, as for why that place has the lowest transparency, maybe as long as you cut this part of the shell, you can find the right answer, right?

"Mr. Wu, I can't tell you why, but by the feeling of my fingers, this place is indeed the thinnest shell. Ren Jiangchi said.

The old man surnamed Wu hesitated for a moment, and finally nodded and said, "Okay, let's open a line from here first and see how the effect is!"

Unlike Erqing, the old man surnamed Wu did not use a clamp, after starting the stone solving machine, he held the rough stone with his hand and carefully touched the saw blade.

Through the reading glasses, the old man surnamed Wu saw that the flesh in the line was jet black, and it was extremely beautiful.

"How is it, Uncle Wu, how is it?" Fan Yanjiao asked anxiously beside her.

"How about it, girl, you have made a fortune!" the old man surnamed Wu looked at the black line on the rough stone excitedly and said excitedly.

"Yes, yes, show it to me!" Fan Yanjiao reached out to grab the rough stone.

"What are you in a hurry?" the old man surnamed Wu opened Fan Yanjiao's hand, "With your half-hung eyesight, what can you see in this line?" Wait a minute, let me open this line a little bigger!"

While speaking, the old man surnamed Wu started the stone dissolving machine again and carefully touched the rough stone in his hand.

The female shopkeeper and the shop's stone master Erqing watched in horror. As professionals, they know how difficult it is for the old man surnamed Wu to operate like this.

Ordinary people want to open the window of the original stone, and they choose a hanging mill or a hand-held electric grinder, but the old man surnamed Wu is a master of art and bold, and directly holds the original stone on the chainsaw blade of the stone dissolver to open the window. Not to mention anything else, just this hand of window opening kung fu, ordinary people can't practice it without twenty or thirty years!

As the calciner sizzles, the line on the rough stone gradually expands, and the larger it expands, the more black the flesh appears!

Soon, that line became a small window the size of a fingernail of a little thumb.

The old man surnamed Wu stopped, wiped the water and powder at the window with a soft cloth, and rushed to the outside of the store with the original stone, with the help of the natural light outside, to observe the jade flesh under the window.

Ren Jiangchi has heard Rao Dongcheng talk about this truth, and the so-called don't look at jade under the lamp. This means that the best way to view jade is in natural light. Because when you look at jade under the light, there will be different deviations in the color of the jade because of the different light sources.

Take jadeite as an example, if you use a white light source to illuminate colorless jadeite, it will appear more transparent. If you use yellow light to shine on green jadeite or yellow jadeite, the color of the jadeite will appear more intense. This is also the principle of why gambling stone players should use a white light flashlight to see through the cracks, and a yellow light flashlight to see the color.

Therefore, it is best to observe jadeite under natural light, so that the effect presented is the most realistic effect.

The vast majority of jadeite shops also use this principle to install the lights in the store into tungsten lamps that glow yellow, so that the jadeite looks more vivid and more exciting.

Fan Yanjiao also chased out and stood behind the old man surnamed Wu to observe. I saw that the jade at the small window on the rough stone was black and translucent under the illumination of natural light, and the leather shell next to it was as thin as a book cover.

The old man surnamed Wu took out a flashlight again, and shone it into the small window, only to see that the flesh inside was clear and bright, and the most important thing was that there was no trace of cotton in it.

"Big rise, big rise!" The old man surnamed Wu laughed out loud and said to Fan Yanjiao: "Aunt Jiaojiao, your Uncle Wu's eyesight is okay, right? The rough stone selected for you will be sold for at least 800,000 yuan." ”

"Hmph, Uncle Wu, the cowhide is about to be blown into the sky by you! If your eyesight is really good, why do you need a big man to identify it, just tell me that this rough stone is super valuable?" Fan Yanjiao smiled mercilessly.

"I did think it would rise, but I didn't expect it to rise so much!" The old man surnamed Wu didn't care about Fan Yanjiao's sneer, and lowered his head to carefully observe the leather shell next to the small window, and then said to Ren Jiangchi: "Jiang Chi, do you know why I couldn't light up here before?"

"Please also ask Mr. Wu for advice!" Ren Jiangchi really wanted to know the answer.

"If you look at the shell here, half of it is black, which means that this part of the shell is very iron, and it was reduced to a ferric mineral in the deep layer of the rough sedimentary layer. The hardness of iron ore is generally between 2 and 5.5, far lower than the hardness of jadeite 6.5-7, so when this layer of skin is weathered, it will weathered a little faster than the rest of the rough stone, so it is thinner. And because half of the cortex is black, it blocks the light of the flashlight, and the transparency is significantly lower than the rest of the rough. ”

"I see! Thank you, Mr. Wu!" Ren Jiangchi suddenly realized and expressed his gratitude to the old man surnamed Wu for his professional analysis.

"Yes, thank you!" The old man surnamed Wu turned around and handed the original stone in his hand to Fan Yanjiao, and said: "Jiaojiao girl, there is nowhere to find it when you step on the iron shoes, and it takes no effort to get it." A few months ago, your mother asked me to find a high ice field stone carving a Maitreya Buddha to worship, and I have never met a suitable one. Now you can give this high ice rough stone to her as a Mother's Day gift, and you will definitely be happier to choose a rough stone full of greenery!"

"I don't want her old man to be happy, as long as she scolds me less!" Although Fan Yanjiao said this, she had already begun to imagine her sister's surprised expression when she took out this high ice rough stone and presented it to her mother during the family banquet in the evening.

"Eldest sister, I'm on the right for this first stone, right?" Ren Jiangchi interrupted Fan Yanjiao's imagination by interjecting inophinously, "Then should I go to the second stone now?"

"The second stone? Okay!" Fan Yanjiao was like Zhu Bajie who had just eaten ginseng fruit, and turned her head to ask the old man surnamed Wu: "Uncle Wu, according to the rules of your stone gamblers, have you found a good stone and want to wrap a big red envelope for the gambling stone consultant?"

"Yes, girl, how big of a red envelope are you going to give Uncle Wu?" asked the old man surnamed Wu with a smile.

"Phew, Uncle Wu, you are an elder, and you are embarrassed to accept my red envelopes?" Fan Yanjiao took a sip and said: "I am planning to give a red envelope to the big man, after all, I will hire him as a gambling consultant in the future, if I behave stingily now, what should I do if he doesn't work hard in the future, big man, don't you say?"

"Eldest sister, I still want to keep my fingers, and I definitely don't dare to work or contribute!" Ren Jiangchi said with a smile.

"Okay, don't pretend, I obviously want it in my heart~!" Fan Yanjiao groaned for a while, and snapped her fingers suddenly, "That's it, big man, I won't wrap another red envelope." Isn't there a second rough stone? As long as you can be like the first rough stone, and know exactly what is in it, then this second rough stone will be given to you as a red envelope!"
