The second update, why are the recommendation tickets so unsatisfactory?

Doghead gold is a naturally generated gold nugget. Because it looks like a doghead, it is given this vivid name. There is also a name for **hoof gold, which is also named after the shape.

Whether it is dog-headed gold or horse-hoof gold, they are all general terms for natural gold nuggets by ancient people. In fact, the shape of natural gold nuggets is very strange, and there are very few dog-headed gold or horse-hoof. However, these titles are more popular and have been used all the time.

After listening to Qi Fei's introduction, Wang Zhuo thought: "In other words, is this thing formed naturally?"

The surface of the gold nugget on the table was uneven, as if it had experienced countless years of baptism, and the mud and sand in the gap had not been completely washed away, and it looked vicissitudes and ancient.

"This is a treasure." Qiu Lu smiled and said, "There are very few dog-headed gold in the world. It is said that during the Qing Dynasty, there was an official who sent many people to find this thing, and wanted to get it back and give it to Empress Dowager Cixi as a birthday gift, but in the end they were not found."

Qi Fei nodded and said, "Yes, so some people say that gold is hard to come by. It is precisely because of its preciousness that it is regarded as a symbol of blessing."

Wang Zhuo said oh, nodded, picked up the piece of gold on the head and flipped over and asked, "The naturally formed golden lump? Then what is inside it? Is it all golden?"

"That's not." Cai Yuantu said: "There are three types of gold in dog heads, including gold-covered stone, stone-covered gold, and gold-covered water. This piece is gold-covered stone. There should be a stone in the core, otherwise its proportion will be wrong. The whole gold cannot be so light."

Qi Fei explained: "Golden heads are not pure gold, generally purity is about 70%. The impurities are other metals, some are copper, some are silver or iron, etc.."

Hearing this, Wang Zhuo had a rough understanding of the dog-headed gold. He looked at the piece of dog-headed gold with a magnifying glass, quietly used his perspective eyes, passed through the magnifying glass and the surface of the dog-headed gold, and looked inside.

When he saw this, he was surprised to find that as soon as his vision penetrated a few millimeters of thickness, the golden layer on the surface passed, and there was a white pebbles inside. Strangely, the surface of this pebbles had traces of corrosion, as if it had been bitten by a bug.

Another suspicious point is that the transition between gold and pebbles is too direct. Although the two are tightly attached, the river water does not interfere with the separation state of river water, which is completely different from the shell form of jade wool.

Turning the dog-headed gold in a direction and looking through again, Wang Zhuo finally came to a conclusion that this thing was a fake, because when he looked in from this angle, he saw that the golden clothes on the surface were divided into three layers, the bottom layer had a cut sharp corner, and there were obvious carving marks on the surface of the pebbles on this side. It was obvious that it was handmade and was by no means natural.

When he put it in the magnifying glass, Wang Zhuo had a certain plan in his mind. Even the process of making this piece of dog-headed gold was guessed.

"This thing is about four liang, right?" Wang Zhuo weighed it and asked with a smile: "Boss Cai, how much did he buy it?"

"You're very accurate in estimating this thing. I've weighed it, 206 grams." Cai Yuantu smiled faintly and said, "I wanted to buy it yesterday, but I didn't sell it."

"It's just such a thing, someone paid 200,000?" Wang Zhuo was stunned for a moment and asked with a smile: "The pure gold is only about 300 per gram, and its purity is only about 70% of it. If there is another stone inside, it is worth 1,000 per gram?"

"Wang Zhuo, the account is not calculated like this." Qiu Lu interrupted with a wry smile: "Rice paper and ink are not worth much. If Tang Bohu paints paintings, they are worth hundreds of millions. Dog-headed gold is a treasure of nature. Its value lies in cherishing. You cannot measure its gold value."

"Don't underestimate this small piece of thing." Qi Fei said: "Dog-headed gold is aggregation of microorganisms. Just a lump of things may take millions of years, or even tens of millions of years to form."

Cai Yuantu nodded and said, "It's a bit like the process of forming corals, but it's much slower than that."

"Millions of years? It's enough for me to watch it for a few days." Wang Zhuo smiled and looked at Cai Yuantu: "Boss Cai, this thing is a high-quality imitation. Did you use it to test my eyesight or was it slap in the eye?"

"You said it was fake?" Cai Yuantu's smile gradually faded, and his brows frowned slightly.

"Haha." Wang Zhuo smiled and nodded, "It's not true if it's fake. No matter how many times it can make the real fake, it will sooner or later be exposed."

"This piece of gold in my hands has been in my hands for more than ten years." Cai Yuantu said in a deep voice: "Wang Zhuo, Miss Qi, Xiao Qiu, I'll tell you that I had to get back this thing back then, and it was worth 10,000 yuan. I asked many people to help me see it, which is what I said now, and they all said it was a real thing. However, the person who used it to pay off the debt said that this thing was bought by a Henan tomb robber, which was almost the same as the unknown origin. You should also know that Henan is a big den for counterfeiting antiques, so I always feel that I can't believe in this thing."

After a pause, Cai Yuantu smiled faintly and said, "It's because of this reason that I haven't sold this thing. I'm afraid that if it's a fake, I'll give me a reputation of being a scam and cheating person. I don't need this little money. If it's a fake return, it's fine. The key is that I can't afford to lose this face."

"Is this thing fake? How did you see it?" Qi Fei picked up the piece of gold, You Zi didn't believe it, and looked it carefully again.

Old God Wang Zhuo was drinking tea, "I said it was fake, but it didn't dare to be real, and no matter how many experts came, it would be easy to use."

Qi Fei glanced at him and shook his head and said, "I really don't believe it anymore. So many people can't see it. Are you so good at seeing it?"

"Then let me tell you how this thing is made first." Wang Zhuo grabbed two olive fruits and threw them into his mouth.

The three of them immediately laughed. This guy didn't even know what the dog-headed gold was half an hour ago. Now I dare to tell you how to make fake dog-headed gold. Can you stop making such a spoof?

Qi Fei smiled and said, "Okay, let's hear how you're going to break up."

Wang Zhuo cleared his throat and said: "First take a piece of pure gold and add some copper, silver, tungsten and other things. Anyway, it's a metal with strong ductility. Do you all understand the ductility?"

Qiu Lu nodded: "I learned physics class."

Qi Fei said no: "Gold has the strongest ductility, and the ones you mentioned are a little worse."

Cai Yuantu smiled and said, "I can understand it even if I haven't learned it. Wouldn't it be enough to just say softer metal?"

"Just understand." Wang Zhuo continued to preach: "Create these metals and pure gold together, drip them into gold beans, flatten them, and make them into handmade gold foil. Do you know what handmade gold foil is?"

Qi Fei gave him annoyed look: "Don't interrupt, let's continue talking."

Cai Yuantu's expression became solemn, as if he had thought of something.

"The gold foil is thicker. Of course, our gold is not pure enough, and it is not okay to be thin. Anyway, that's the case, it's about two or three millimeters thick."

"Stop it." Qi Fei interrupted, "Two or three millimeters are called gold pieces, not gold foil."

Wang Zhuo said oh, not thinking: "Anyway, it's almost the same, so just hit it into a millimeter."

Qiu Lu also shook his head and said, "One millimeter is too thick. The thickness of gold foil is microns, which is a thousand times different."

"Then you can make a millimeter of gold pieces!" Wang Zhuo finally lost and continued to preach: "Then you find a stone. The shape should not be too regular. If it is too small, you can make little money. If it is too big, you can first estimate whether the gold pieces you made can be wrapped. Use the gold pieces to wrap it tightly, don't be reluctant to pay, you must wrap it a few more layers."

"Then throw this semi-finished product into the acid solution. I don't know what acid is. Anyway, it's the kind of acid that can't melt gold but can melt other metals. You can try it yourself if you soak it in the acid solution a few times. After soaking it in the acid solution, the brand new dog-head gold will come out. It's more delicate than microorganisms and coral than corals. Oh, it's so beautiful, like a handicraft, so you have to oxidize it first and look older. Next, you can make some river mud and apply it, and then find a mixer. It's better to be new, and you haven't been stained with artificial things like cement white ash. Put some river sand, stones, rotten grass roots and so on. Throw our dog-head gold into it and stir it until you feel it's OK."

"That's how our dog-head gold is made?"

"Yes, it's that simple, you can do as much as you want at a time."

Cai Yuantu pointed to the dog-headed gold on the table: "Then, I did this too?"

"That's right." Wang Zhuo answered neatly.

"Do you have a way to prove it?" Qiu Lu asked everyone's most concerned questions.

Wang Zhuo looked at Cai Yuantu and smiled and said, "If it proves, this thing will be ruined."

Cai Yuantu spread his hands generously and said, "If it is destroyed, it will be destroyed. Just don't destroy it and tell me that this is a real thing."

"Okay, you guys take a closer look." Wang Zhuo picked up the gold on the table, turned around and looked at the right position, clasped his hands tightly and broke it hard!

Unfortunately, Guan Yingying and others were not present, otherwise they would have discovered that the scene in front of them was surprisingly similar to the one that happened in Shangdonglou, except that the things in Wang Zhuo's hand were replaced by blue and white porcelain to a piece of dog-head gold!

Wang Zhuo did not have the ability to break gold with bare hands, but it was more than enough to break the golden clothes wrapped around the surface of the stone. Moreover, this golden clothes had been treated with acid liquid and had been corroded and had long been corroded and riddled with holes.

With a "click", a stone fell on the table, and a few flying dust raised. Wang Zhuo glanced at the inside of the peeled gold shell, smiled and nodded, and handed it to Qi Fei beside him.

Cai Yuantu and Qiu Lu were about to put their heads over, Wang Zhuo picked up the stone and said, "Boss Cai, Brother Qiu, please look at this stone."
