My Deep-sea Fishery

"Who is right about this? Please ask after you go back." Xiang Yang smiled.

To say that its color is good-looking, the price is expensive, Xiang Yang feels that it is inaccurate.

Because tourmaline is a gemstone whose quality is not determined by color.

Tourmaline has many colors. Because tourmaline is a complex borosilicate mineral, some metal ions such as iron, magnesium, lithium, manganese, aluminum, etc. can be substituted for each other. The content of each ion is different, which will directly affect The color of tourmaline and its type are different.

For example, if there is more iron, the tourmaline appears black and green.

If there is more magnesium, it shows yellow and brown.

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

Although azure and bright red roses and red tourmalines can be called top grades, in the same tourmaline crystals, due to the uneven distribution of components, it often leads to color changes, so the tourmaline will also appear bi-color tourmaline, Various types such as multi-color tourmaline or inner-infrared green watermelon tourmaline.

Therefore, the color pleochroism of tourmaline does not distinguish the price by color.

Xiang Yang looked at Chen Qingsheng and joked: "I think you love this tourmaline. Would you like to sell it for 10,000 yuan?"

Chen Qingsheng hurriedly returned it to Xiang Yang, "Boss, you are not kind, let alone how much this quality tourmaline is worth, you are not even sure if it is tourmaline, you just sell it for 10,000 yuan. Give it to me, it's too dark."

Xiang Yang laughed, "When I'm sure, then maybe it won't be the price."

Chen Qingsheng shook his head, "I'll take a gamble if it's five hundred yuan, and I don't want it if it exceeds five hundred."

Xiang Yang rolled his eyes, "Unless this piece of gadget is a piece of glass, you will make it for you. Do you think I will bet with you?"

"In fact, it is very simple to determine whether this piece of thing is tourmaline." Xiang Yang said.

Chen Qingsheng wondered: "Boss, do you know how to identify?"

Xiang Yang shook his head. In the shopping mall, I don’t know how to distinguish between true and false, because the current counterfeiting technology is so awesome, and I don’t know very well about tourmaline, but when I meet someone who looks alike outside, I’ll identify it. Whether the thing is tourmaline or not should still be okay.

Xiang Yang told Chen Qingsheng the principle of identifying tourmalines.

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, the columnar tourmaline will produce electrode effects at both ends. One end is positive and the other end is negative. This will cause the tourmaline to pick up some dust or The little confetti was attracted.

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

After listening to the principle, Chen Qingsheng suddenly realized, he quickly said: "Boss, shall we try now?"

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

Chen Qingsheng was not welcome, and took the tourmaline, and then baked it with a lighter.

After roasting for more than ten seconds, the lighter was hot. Chen Qingsheng felt that this tourmaline was also a bit hot, so he took a cigarette out of 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 tobacco in the palm of his hand.

The tobacco in his palm didn't move.

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

"Your method of identification is wrong. After so long, the tourmaline is cold. I'll try it." Xiang Yang took the tourmaline and quickly rubbed it on his clothes.

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

"Impossible." Xiang Yang said immediately.

There is a story related to tourmalines. It is said that on a warm summer in 1703, several children in Amsterdam, the Netherlands, were playing with the stones brought back by the Dutch Voyager. Suddenly a child discovered these stones, nearby dust and grass. After analyzing the crumbs, the children were very surprised, so they called their parents to look at them. Sure enough, they found that these stones can really attract or repel very light objects, such as dust, grass clippings, etc., so the Dutch have taken It is called sootstone, and it is also used to clean the soot in the pipe.

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

The tobacco still doesn't move.

The two of them stared wide-eyed.

"Boss, could it be the reason for the dampness of this tourmaline? How about let's dry it and try again?" Chen Qingsheng asked.

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

"Haha, I caught it, Brother Yang, look at it, I caught this lobster." At this moment, Fang Youqun was holding a large lobster in his hands and ran over here happily.

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

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

Xiang Yang's face turned dark, Fang Youqun didn't say anything. He hadn't noticed that 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."

"Bliss? I 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 five hundred yuan, do you want it?"

Chen Qingsheng looked at Fang Youqun, UU read www. uukanshu.com then looked at Xiang Yang, and finally looked at the blue thing.

"Not to mention, this thing, the more it looks like the bottom of a beer bottle, shouldn't it really be the bottom of a beer bottle?" Chen Qingsheng said silently.

Xiang Yang nodded silently. It was too embarrassing. Although he knew that organic gems had always been his shortcoming in all ocean knowledge, he held a beer bottle bottom as tourmaline, and he and Chen Qingsheng talked about it. After a lot of experiments to detect true and false, Xiang Yang now wants to find a gap to get in.

Chen Qingsheng's face turned green. He turned his head and looked at Fang Youqun angrily, "I don't even know Bixi, I don’t even know that I have never had a beer before. Don’t say I know you in the future. Bixi is beer. Moutai in China."

Fang Youqun scratched his head, "Really? It turned out to be a high-end beer. No wonder a bottle can be sold for 500 yuan. This wine costs tens of thousands of yuan a bottle? I don't know when I have a chance to try the taste. "

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