My Deep-sea Fishery

"Who can say for sure? Ask when you get back." Xiang Yang said with a smile.

Xiang Yang thinks it is not accurate to say that its color is good-looking and its price is expensive.

Because tourmaline is a gemstone that does not determine its quality by color.

There are many colors of tourmaline, because tourmaline is a complex borosilicate mineral, in which iron, magnesium, lithium, manganese, aluminum and other metal ions can replace each other, and the content of each ion is different, which will directly affect the The color of tourmaline and its type are different.

For example, if there is more iron, tourmaline will appear black and green.

If there is more magnesium, it will show yellow and brown.

For example, lithium and manganese, these are more, then it will show a kind of rose red or blue and so on.

Although blue and bright red roses and red tourmalines can be called top grade, in the same tourmaline crystal, due to the uneven distribution of ingredients, it often leads to color changes, so tourmaline will also appear double-color tourmaline, There are various types such as multi-colored tourmalines or inner infrared green watermelon tourmalines.

Therefore, the price of tourmaline with pleochroism is not distinguished by color.

Xiang Yang looked at Chen Qingsheng and joked, "I see you can't put it down because of this tourmaline. Do you want to sell it to you for 10,000 yuan?"

Chen Qingsheng hurriedly returned it to Xiang Yang, "Boss, you are not being kind. Let alone how much a tourmaline of this quality is worth. Now you are not even sure if it is a tourmaline, so you can sell it for 10,000 yuan." It's too dark for me."

Xiang Yang laughed, "When I'm sure, it might not be the price."

Chen Qingsheng shook his head, "If it's five hundred yuan, I'll take a gamble. If it's more than five hundred yuan, I won't take it."

Xiang Yang rolled his eyes, "Unless the five hundred yuan is a piece of glass, you will earn it anyway. Do you think I will bet with you?"

"Actually, it is very simple to determine whether this piece is a tourmaline." Xiang Yang said.

Chen Qingsheng asked suspiciously, "Boss, do you still know how to appraise?"

Xiang Yang shook his head, in the shopping mall, I don’t know how to distinguish the real from the fake, because the current counterfeiting technology is too powerful, and I don’t know much about tourmaline, but I met someone who looks like it outside, I will identify this It should be no problem whether the thing is a tourmaline or not.

Xiang Yang told Chen Qingsheng the principle of identifying tourmaline.

It turns out that tourmaline is also called tourmaline, because tourmaline has piezoelectric effect and pyroelectric effect.

What does that mean?

When the tourmaline is heated or pressured, or rubbed with silk or wool, an electrode effect will be generated at both ends of the columnar tourmaline, one end is positively charged, and the other end is negatively charged, which will make the tourmaline put some dust or Small confetti to attract.

This magical power is the piezoelectric effect and pyroelectric effect of tourmaline, which is also the origin of the name tourmaline.

Chen Qingsheng suddenly realized after listening to the principle, he quickly said: "Boss, let's try it now?"

Xiang Yang smiled and handed the blue stone to Chen Qingsheng, "You smoke, you have a lighter, try it."

Chen Qingsheng was also polite, took the tourmaline, and then roasted it with a lighter.

After roasting for more than ten seconds, the lighter became hot. Chen Qingsheng felt that the tourmaline was a little hot, so he took out a cigarette from the cigarette case and squeezed some shredded tobacco on the palm of his hand.

"Look." Chen Qingsheng held the heated tourmaline in his other hand, and slowly approached the shredded tobacco in his hand.

The shredded tobacco in his palm remained motionless.

"Boss, after the appraisal, this is not a tourmaline." Chen Qingsheng said.

"Your identification method is wrong. After so long, the tourmaline is cold. Let me try it." Xiang Yang took the tourmaline, and then quickly rubbed it on his clothes.

"Could it be a problem with shredded tobacco?" Chen Qingsheng asked.

"Impossible." Xiang Yang said immediately.

There is a story related to tourmaline. It is said that in a warm summer in 1703, in Amsterdam, the Netherlands, several children were playing with the stones brought back by the Dutch voyagers. Suddenly, a child discovered these stones. The dust and grass nearby After analyzing the crumbs, the children were very pleasantly surprised, so they called their parents to have a look, and they found that these stones can really attract or repel very light objects, such as dust, grass clippings, etc., so since then the Dutch put He is called a limestone, and it is also used to clean the soot in the pipe.

Holding the tourmaline, Xiang Yang quickly rubbed it dozens of times on the clothes, and then approached the shredded tobacco in Chen Qingsheng's palm.

Tobacco was still motionless.

The two stared at each other.

"Boss, could it be that this tourmaline is wet? How about we dry it and try again?" Chen Qingsheng asked.

Xiang Yang frowned, "Forget it, don't try it, take it back and ask someone who understands it."

"Haha, I caught it, Brother Yang, look, I caught this lobster." At this time, Fang Youqun ran towards this side dancing with a big lobster in his hands.

"Hey, Brother Yang, what are you doing with the bottom of a beer bottle in your hand?" Fang Youqun asked puzzled.

"Huh?" Xiang Yang and Chen Qingsheng both looked at Fang Youqun.

Xiang Yang's face darkened, Fang Youqun didn't say anything, he hadn't noticed yet, the more this thing looked more like the bottom of a beer bottle, but the edges were smoothed by the rolling fine sand.

Chen Qingsheng shouted: "Shut up if you don't understand, this thing is called tourmaline."

"Bixi? I've only heard of Qingdao and Yanjing, oh, and Budweiser." Fang Youqun wondered.

Xiang Yang silently turned his head to look at Chen Qingsheng, "I'll sell this thing for 500 yuan, do you want it?"

Chen Qingsheng looked at Fang Youqun, then at Xiang Yang, and finally at the blue thing.

"Not to mention, this thing really looks more and more like the bottom of a beer bottle. Could it really be the bottom of a beer bottle?" Chen Qingsheng said speechlessly.

Xiang Yang nodded silently, it was too embarrassing, although he knew that organic gemstones had always been his shortcoming in all the marine knowledge, but he took the bottom of a beer bottle as a tourmaline, and made it with Chen Qingsheng with great relish. After conducting a lot of experiments to test the true and false, Xiang Yang can't wait to find a crack to get in now.

Chen Qingsheng's face turned green all of a sudden, he turned his head, and looked at Fang Youqun angrily, "I don't even know about Bixie, I can see that I have never drunk beer, don't tell me I know you, Bixie is beer Moutai in China.”

Fang Youqun scratched his head, "Really? It turned out to be high-end beer. No wonder the bottom of a bottle can sell for five hundred yuan. This wine costs tens of thousands of yuan a bottle, right? I don't know if I will have a chance to try it. "

"You have no chance. A bottle of this wine costs millions." Chen Qingsheng said blankly.
