Chapter 149 Selling Gold Bars

After Xie Chuncheng entered the mountain.

Jingshan was bored alone.

I wanted to go out and see if there were any gold shops open.

Ask someone to help identify whether the gold bars in his hand are extremely pure pure gold.

The dish will definitely be open on the first day of the Lunar New Year.

However, Caibai only identifies and recycles gold jewelry from formal sources. You must have a purchase invoice or receipt before they can authenticate it for you.

If there is no receipt, they will not be collected and appraised.

Only private pawn shops and gold shops accept this kind of unexplainable gold.

Of course, the recycling price will be relatively low, after all, people have to bear the risk.

It would be nice if Zhou Ling was here, and Jingshan wouldn't have to trouble outsiders to identify it.

He could go to Zhou Ling directly.

But Zhou Ling took the opportunity to go to England to get tested and took his wife to travel to the British Peninsula to celebrate the New Year.

I will be in Europe during the entire New Year holiday and will not return to my country.

Jingshan didn't know anyone else who opened a shop like this.

So I could only search the addresses of several gold shops and pawn shops on the Internet.

I drove the big G and tried my luck at these gold shops.

The first few stores he visited were all closed.

There are notices posted on people's doors.

Normal business will not resume until after the Spring Festival holiday.

Jingshan finally found a private pawn shop near Liulichang.

It's still open for business on New Year's Day.

In view of the other party's professionalism, Jingshan has to give him some business.

parking.

Enter the door.

Jingle bell, the traditional doorbell rings.

A grey-haired old shopkeeper looked over at Jingshan.

Jingshan walked over and chatted with the old master, and learned that this old master, who was nearly [-] years old, was the owner of this pawn shop, and his surname was Bai.

Jing Shan took out a golden rod and expressed his intention to sell the golden rod.

Boss Bai took the golden stick and looked at it repeatedly.

Despite his decades of vision, he couldn't figure out what the golden stick was used for.

He had never seen such a round rod-shaped gold bar before.

Then he asked Jingshan: "How did you get this gold bar?"

Editor Jingshan said: "It was a gift from a friend."

Boss Bai asked again: "Do you have any bills or anything like that?"

Jingshan: "No."

Boss Bai nodded and asked no more questions.

Seeing that Boss Bai didn't express his position, Jingshan asked, "Does our store accept gold bars like this?"

Boss Bai said: "I'll accept it, but since you don't have a receipt for this gold bar, the price we charge will be a little lower than the market price."

Jingshan: "Understood."

Boss Bai: "Then if you are sure to sell it, we will go to the machine to test it."

Jingshan had been tricked by someone using similar tricks before, so he asked in advance: "Is there any charge for the test?"

Boss Bai said: "No charge."

Jingshan: "Okay, you can put it on the machine and check it."

"Take this and follow me."

Boss Bai returned the golden stick to Jingshan, so as not to cause any disputes later.

He politely took Jingshan to the office behind the pawn shop.

There are various testing instruments inside.

Boss Bai pointed to a square machine on his desk that looked like a large microwave oven connected to a computer, and introduced to Jingshan: "This is an X-ray fluorescence precious metal purity analyzer that has just been purchased in our store. This gold bar you have had before. Such an instrument?”

Jingshan said matter-of-factly: "I've never done it before, it's my first time. Will it damage the gold bar if I use this instrument?"

Boss Bai shook his hand and said, "No, don't worry, this is an X-ray, just like a CT scan, it won't cause any harm to the precious metal itself." Jingshan nodded in understanding.

Boss Bai turned on the computer and clicked on the purity analysis software.

After everything is ready.

He opened the lid of the purity meter again and asked Jingshan: "To prevent disputes, please put the gold bars in yourself."

"Can you let it go?"

Jingshan placed the gold bars in the air and asked Boss Bai.

"Yes, just place it wherever you want, slightly in the middle."

Boss Bai put on his reading glasses and prepared to do software analysis.

Jingshan put the gold bars into the purity meter as Boss Bai said, and then helped cover the lid.

Hearing that this instrument used X-rays, Jingshan deliberately stayed away from the purity meter.

Go around to the other side and watch Boss Bai operating on the computer from behind.

Although Boss Bai is old and his eyesight is not very good, he is very good at playing computer games.

He usually uses this purity meter frequently and should check the purity of precious metals frequently.

After adjusting the parameters by three times, five times and two times.

Then I started the purity meter on the computer.

There was only a low buzzing sound coming from the machine.

Boss Bai introduced to Jingshan: "The X-ray scan is being carried out. In less than half a minute, the content of all the metal elements in your gold bar will be analyzed."

Jingshan asked curiously: "What is the principle of this? Can the content of all metal elements be analyzed by using a ray?"

Boss Bai understands this very well and said: "This energy-dispersive X-ray fluorescence spectrometer will generate high-energy X-rays to excite the atomic electron layer, causing the electrons outside the nucleus to transition, resulting in the release of secondary X-ray energy. Different The energy released by elements has different properties, and the detection system measures these energies and quantities to calculate the element content."

Jingshan pretended that he understood Boss Bai's explanation and nodded.

As he spoke, the computer screen displayed the various metal element contents of the gold bars:

【Au:99.99%】

【Ag:0.01%】

【Na:0%】

【Zn:0%】

……

Also shown below is a list of metallic elements, all with zero content.

This gold rod only contains two precious metal elements: Au (gold) and Ag (silver).

The gold content is 99.99% and the purity is extremely high.

When Boss Bai saw the result, he nodded with satisfaction and said, "This is standard Thousand Pure Gold, of high quality."

It was only then that Jingshan finally breathed a sigh of relief.

The products produced by the system are indeed high-quality products!
Boss Bai turned around and asked Jingshan: "Do you only sell this gold bar? Do you sell anything else?"

"I have two more of the same kind. You can test them again."

Jingshan said, taking out the other two straightened golden sticks from his arms and holding them in front of Boss Bai.

Boss Bai took a quick look and saw that these round gold bars were of standard workmanship and felt like relatively sophisticated industrial gold.

He really couldn't guess what it was used for specifically.

I simply won’t guess any more.

Anyway, if he collects these gold sticks, he will break them into gold jewelry and sell them to gold shops at a higher price.

He just earns risk money and handmade money.

It would do him no good to know too much.

Boss Bai asked Jingshan to put the other two gold sticks into the purity meter.

I didn’t take out the one before.

He was going to test these three gold bars together.

Let’s retest the first high-purity gold bar.

The results measured in this way will make people feel more at ease.

After restarting the instrument.

It didn't take half a minute.

The system gives the detection results of metal content——
