Seeing that Fatty Dong was still a little worried, Chu Chen smiled and said: "Fatty Dong, since you are still not worried, then I will teach you a simple way to identify real and fake corals." "You should know that the component of red coral is carbonic acid. Calcium is the same ingredient as human teeth, so tap the red coral gently on the teeth. If the sound is the same as the sound of the upper and lower teeth knocking against each other, then it is real coral. If you don¡¯t believe me, try it! Here, Fatty Dong immediately asked for the coral beads from Su Jinning. "Click! Click!" He knocked the seventy-one coral beads one by one. Everyone was speechless. "Hey! It's really the same as the sound of tapping teeth!" After Fatty Dong tried them one by one, his face was full of joy. Chu Chen originally thought he would give up, but he said with a shy face: "Brother Chu, this is for me I heard that bones can be used to make fake coral, so what should I do?" Su Jinning couldn't help but feel a little annoyed: "Fat man, are you still finished?" "I just want to figure it out!" Fatty Dong laughed. . Chu Chen smiled and said: "Actually, Fatty's spirit is quite good. Sometimes, we should be more truthful like Fatty. In this case, I will tell you some of the methods of coral fraud." "Generally speaking, In the past, there were only a few ways to fake coral, including burning and hanging coral glaze on the outside of the container; wrapping the surface with lead, coating it with a layer of coral patent leather and painting the texture; and carving ox bone or talc into beads, which are infused with red. To pretend to be coral. Nowadays, technology has developed, and there are also laser dyeing (dying) of white coral or coral-like sea bamboo, Gilson's "synthetic coral" and so on. " "In the past, identification was very simple. The "coral" made of materials contains bubbles inside, and the broken areas are shiny, without real coral fingerprint-like patterns; the "coral" made of glass has a shell-shaped fracture, while the real coral gap is smooth; made of flour "Coral" has a black luster, has cracks over time, and makes a dull sound when struck; the "coral" dyed with bone cuticle can be seen immediately by just wiping it with acetone. " Chu Chen said this. The store owner took out a glass bottle and said, "I happen to have acetone here. You can try it." Seeing this, Chu Chen smiled and said, "Boss, you are very well prepared!" The boss spread his hands. , said: "There is no way, we also operate with integrity. Although we will not make those unintentional money, we still have to make customers believe it is not the case!" Chu Chen chuckled and said: "That makes sense, boss, if you do this, don't you? I¡¯m worried that there¡¯s no business!¡± ¡°Hehe, we¡¯re doing this just to make a living!¡± The boss said with a smile, ¡°Brother, you look like you¡¯re in the industry, right?¡± Chu Chen replied with a smile: "I'm in the antique business at Panjiayuan." The boss heard that Chu Chen said he was in the antique business. He quickly took out a business card, handed it to Chu Chen with both hands, and said: "Then we can be considered half of the same industry. I I have connections with Baodao. If you have any demand for coral jewelry in the future, the price will definitely not let you suffer. I am not exaggerating. In other stores, just this string of tower beads does not cost 600, 700,000 yuan. It won¡¯t come down.¡± Chu Chen also believed what the boss said. The price of 520,000 yuan for a MOMO grade coral tower bead of this quality is indeed very cheap on the market. So Chu Chen took the business card handed over by the boss and looked at it. Then he handed him his business card and said with a smile: "Okay, Boss Qian, I will call you if I need anything in the future. Of course, if you have any antiques in this area, you can also call me." "Definitely." "Definitely! " At this time, Fatty Dong had already wiped all the beads, and looking at his happy face, there was no need to say more about the result. "Brother Chu, what other laser dyes are there?" Chu Chen smiled and said: "This is very simple. Since it is dyed, it usually cannot be what it looks like. You can see the dye in the small cracks of the coral with a ten-fold magnifying glass. Neutralize the intergranular concentration, the red color is deep on the outside and light on the inside, and the coloring is uneven. This is the obvious flaw of the fake. In fact, like the coral that is faked by traditional techniques, if you look at it with a magnifying glass, there are generally no natural lines inside, and it is easy to identify. ." With that said, Chu Chen handed a ten-fold magnifying glass to Fatty Dong. After Fatty Dong took it, he looked at it attentively. "Okay, Fatty, you'd better watch it here by yourself, we don't have time to spend time with you." Liu Sizhe was anxious to go gambling, but couldn't stand Fatty Dong's dillydallying, so he called Chu Chen and the others, Just walk to the stone betting shop. "Hey! Wait for me" The store Liu Sizhe mentioned has a simple and easy-to-remember name "Wang's Stone Shop". Needless to say, the boss is probably named Wang, but the group of peopleWhen we arrived at the door of the store, we unexpectedly saw someone making a noise inside the store, which made everyone a little strange. "Old Yu, what's going on?" Liu Sizhe happened to see an acquaintance who often gambled on stones at the door and asked. Old Yu chuckled and said, "What else can we do? That scoundrel Zhang Cheng has crossed over and is cheating!" Hearing this, Liu Sizhe said angrily: "Why is it this guy again? He's always like this. If I were Uncle Wang, I would have done it long ago. I won¡¯t sell it to him!¡± Old Yu said: ¡°After all, Lao Wang is open for business. If he really doesn¡¯t sell it to Zhang Cheng, he will cause trouble here, and Zhang Cheng only dares to ask for it! He is too cheap to do anything too much. " "If he dares to go too far, I won't be able to beat him to death!" Liu Sizhe snorted coldly. Seeing that Chu Chen and the others were confused, he told him the reason. The Zhang Cheng I just mentioned was a gangster himself. He had never been a regular person since he was a child, and he had done a lot of sneaky things. Later, he accidentally heard the story that gambling on stones could make him rich overnight, so he also started gambling. Stone comes. "However, he only relied on his feelings when betting on stones and never studied the knowledge involved in betting on stones. As you can imagine, others lost nine times out of ten when betting on stones, but he basically lost ten times out of ten when betting on stones. But even so, he still enjoys it and believes that good luck will come to him one day, so he often comes here to gamble on stones whenever he has money. However, he was originally a gangster, and it was his nature to cheat and cheat. Every time he came to bet on stones, he would not only cut the price of wool to an extremely low price, but if the bet was too high, he would also ask the boss for another piece of wool. No. Give it to him, and he will grind and make trouble. Anyway, he has plenty of time. Even if he calls the police, the police can deal with this kind of thing today, but they will not be able to deal with it tomorrow. After listening to what Liu Sizhe said, Chu Chen couldn't help but shook his head. Why did he meet so many weird people today? However, when meeting such a two-skinned bastard, unless he uses violence, there is really no other way. Liu Sizhe led Chu Chen and the others in, and saw the Zhang Cheng mentioned earlier and a pair of people who looked like father and daughter, facing each other in a tense situation. According to Liu Sizhe's introduction, the father and daughter were the shop owner Wang Yongcai and her daughter Wang Xiaoyue. Zhang Cheng held a cigarette in his mouth and said nonchalantly to the shopkeeper and his daughter: "I don't care anyway, there must be something wrong with the quality of your wool. Why don't you give me a patch of wool today or refund your money!" Wang Xiaoyue said angrily. : "Don't even think about it, Zhang Cheng, let me tell you, even if we don't do business today, you can't even think of taking advantage of me anymore!" After hearing this, Zhang Cheng sat down on the ground and said with a playful smile: "That's up to you!" "You" Wang Xiaoyue was really angry when she saw his rogue appearance, but then she felt a sense of powerlessness. Apart from following his wishes, she really didn't think of any way to get rid of this rogue. "Okay, Xiaoyue, just give it to him if he wants it. It's good to leave early!" Wang Yongcai helplessly advised his daughter. Wang Xiaoyue said angrily: "I don't! The wool he bought was less than a thousand yuan, but he wants wool that costs hundreds of yuan for us. Where can such a good thing come from in the world!" "This" Wang Yongcai said. I'm a little reluctant to think about it, but the result is real. When you said you wanted to buy a piece of wool, you not only bargained hard, but also asked for a cheaper piece of wool. You actually had the nerve to ask for hundreds of yuan of wool, and you really planned to buy it. One for one! "Zhang Cheng, are you itchy again?" Liu Sizhe suddenly became a little annoyed when he saw Zhang Cheng's rogue appearance. "Who is it! Ihehe, it turns out to be Mr. Liu!" Zhang Cheng originally wanted to curse, but when he looked up, he saw that it was Liu Sizhe. He immediately got up from the ground, nodded and bowed in greeting. It¡¯s not without reason that Zhang Cheng is so afraid of Liu Sizhe. He was beaten by Liu Sizhe before and cried for his father and mother. Afterwards, he called the police, and the police came and took them to the station. Liu Sizhe was fine, but he was locked up for a week. , this incident immediately let him know that Liu Sizhe was not something he could offend at all. Seeing that Liu Sizhe still had a straight face, Zhang Cheng's heart trembled, and he quickly said: "Master Liu, I can't help it. I've been tight lately, so" Before Zhang Cheng could finish his words, Liu Sizhe interrupted him. , scolded: "You damn thing, you are so tight and you still come here to gamble. If you keep talking nonsense, believe it or not, I will beat you up all over the floor." Zhang Cheng said in fear after hearing this: "Believe it! Believe it! I'm leaving! I'm leaving right now!" After saying that, he started to walk out. "Wait!" Chu Chen shouted at him before he could take a few steps. Zhang Cheng thought that Liu Sizhe and the others would not let him go, so his calves were trembling with fear from the shout. He turned around and said with a smile on his face: "This this brother, what do you want to tell me?" Chu Chen pointed to the two pieces of wool on the ground and asked: "Are these two pieces of wool yours?" Zhang Cheng saw that it was not what he thought, and he couldn't help but breathed a sigh of relief and replied: "Yes, no Do you know what¡¯s going on with this big brother?¡± Chu Chen smiled and said, ¡°How about I spend three hundred yuan to buy these two pieces of wool?¡± ¡°Ah!¡± Chu Chen¡¯s words not only made me happy, Zhang Cheng was a little dumbfounded, and others present were also dumbfounded.
