Chu Chen then talked eloquently: "Actually, the formula dense wax made of amber is pretty good and has some value, but the Middle Eastern aristocratic dense wax is actually basically an artificial fake, made of polymer artificial resin. , the cost is only a few dozen yuan. These are just handmade jewelry. It¡¯s OK to buy them for a little money, but there is no need to spend a lot of money.¡± ¡°Ah!¡± the little fat girl exclaimed: ¡° Brother Chu, what kind of aristocratic beeswax is this? Isn¡¯t it the aristocratic beeswax from the Middle East?¡± Chu Chen said helplessly, ¡°This doesn¡¯t count as anything, it¡¯s just a plastic bead.¡± "Well, how could they be plastic beads?" The little fat girl said in surprise: "Look, there's some paste on it. The person who sold it to my dad said it's an old noble beeswax that's over a hundred years old!" "Who said there were no plastic beads more than a hundred years ago?" Chu Chen asked. "Plastics did exist more than a hundred years ago, but no one is so stupid that they would wear this kind of thing all the time, right?" Chu Chen explained: "There is a reason for this. European colonists made it more than a hundred years ago. A large number of plastic beads were sent to Africa in exchange for resources, because people there lacked understanding of plastics at the time and thought they were precious gems. These plastic beads were what was historically known as "trade beads." "But maybe they were. Come on, a hundred years later, these "very precious" plastic beads flowed back to European antique shops and were sold to Europeans at very expensive prices, and your string of beads should be one of them." " This" After hearing Chu Chen's explanation, the little fat girl didn't know what to say. "Brother Chu, how do you know if it is real beeswax?" Su Jinning asked with concern. She had wanted to buy a beeswax bracelet before, but she didn't expect that there were so many things involved. Chu Chen smiled and said: "Actually, the amber and beeswax we are talking about are the same thing. Simply put, the transparent one is called amber, and the opaque one is called beeswax. Because beeswax looks like honey and wax, and is opaque from bright yellow to dark red. It was called beeswax by the ancient Chinese, so you can use the method of verifying the authenticity of amber. "The density of beeswax is between 1.05 and 1.10, so it will float in saturated salt water. This method can eliminate most fake beeswax. In addition, beeswax has natural texture, which is soft and irregular. Many imitation products have no texture or rigid texture. Also, beeswax is an organic gemstone and cannot be worn in summer. It's very hot, and it won't be too cold to wear in winter. It's very gentle, which is also a characteristic of beeswax." At this point, Su Jinning asked: "Brother Chu, I heard that if it is real beeswax, it will smell good when you rub it with your hands. "Really?" "Yes!" Chu Chen nodded: "But there is a misunderstanding. Generally speaking, new beeswax has little or no scent when rubbed by hand, only the older beeswax skin. The more you rub it, the more fragrant it will be. In addition, you can use a hot needle to identify the beeswax. The real beeswax will explode and release fragrance, but it is better not to try this method. Instead of doing this, you might as well spend some money. Let's do a scientific appraisal." "Oh!" Su Jinning nodded clearly, and then asked: "Brother Chu, how do you identify the noble beeswax made of amber? "That one is very simple. Under strong light, the texture inside of the secondary processed beeswax is like silk feathers, while the texture of real natural beeswax is like clouds." Chu Chen Take a sip of tea. Then he said: "As for old beeswax, it can generally be judged from several characteristics of its appearance. First of all, old beeswax is prone to produce orange peels when weathered. Of course, this phenomenon may not be visible in places that are often touched. But. There must be places that cannot be touched. Secondly, the mouth of the hole is naturally shaped like a pig's mouth. "Thirdly, as I just said, the older the skin of the beeswax is, the more fragrant it will be. That is, the older the beeswax looks, the more transparent it looks. Finally, the natural weathering of old beeswax will produce a pattern similar to that on fly wings, which is caused by water loss and is most obvious inside the pores. "But I advise you, if you don't know much about beeswax, it is better to buy new beeswax. The water in old beeswax is too deep, and you will get a hole if you are not careful." "There are also noble beeswax and regenerated beeswax. These are not natural after all. If you want to invest, it is better not to buy them." Seeing that none of the features Chu Chen mentioned are on his bracelet, Xiao The fat girl really wanted to cry without tears. Things she bought for tens of thousands of dollars were only worth tens or even hundreds of dollars. This result really shocked her. After feeling dejected for a while, the little fat girl suddenly remembered that she still had an amber pendant, so she quickly took it out, put it on the table, and asked anxiously: "Brother Chu, could you please help me look at this?"Please tell me, is it really green amber? "Chu Chen nodded, took it into his hand and looked at it carefully, then looked at the light, and then put the thing back on the table. "How's it going? "The little fat girl asked cautiously. "This pendant is indeed amber, but" "Ah! What¡¯s the problem! "At first, the little chubby girl was quite excited. When she heard the word "but", her whole face immediately dropped. "Let me first tell you what green amber is. "Chu Chen secretly shook his head and said: "The color of green amber is the same as that of blue amber, both due to an optical phenomenon produced in the sun. Looking at the light source, blue amber and green amber are both golden yellow, honey color or even red. And your piece of green amber is indeed grass green when viewed against the light source, so it should be the color of baked amber. " "This profiteer! "The little fat girl said angrily: "I bought it in a large jewelry store over there. He actually sold me a fake thing and gave me a certificate. I must look for it when I go back. He settles the score! " "It's no use looking for him! Chu Chen shook his head and said: "The roasted color of amber is called optimization in the jewelry industry. According to international and Chinese industry rules, optimization does not need to be specially stated when selling. The certificate also says natural amber." " "Isn't it? Isn¡¯t this justified? "The little fat girl wailed, while the others all looked at each other. Chu Chen spread his hands and said: "So, it is better to keep your eyes open before buying this kind of thing, but the texture of this thing is indeed amber, as long as If you like it, the price is right, so you can wear it. " "Why! The little chubby girl sighed in frustration and said, "I've been wearing this thing for more than a year, and I quite like it. Just wear it like this." "As she said that, she picked up the pendant and put it on again. Seeing the appraisal results of the two things of the little chubby girl, Su Jinning was somewhat repelled: "I didn't expect that there are so many ways to deal with amber and beeswax. I won't buy it yet. . " Fatty Dong nodded quickly and said: "Yes, it's better not to buy it for now, otherwise it will be very distressing if you buy a fake. " "snort! You damn fat man! I saved you money by not buying it. Are you very happy? "Su Jinning snorted coldly. Fatty Dong chuckled and said: "How can you! One gram of new beeswax is less expensive than gold, so how could I not part with this little money! " "This is what you said, then go buy me a string of beeswax bracelets in the next few days, otherwise I want you to keep an eye on it! "As he said that, Su Jinning raised his fist. "This" "What, you don't want to? ! " "hey-hey! Fatty Dong laughed dryly: "How can that be impossible!" I'll buy it tomorrow or the day after tomorrow, right? " "You know what I mean! " Seeing Fatty Dong's distressed look, everyone laughed secretly. When Chu Yulan and the others were about to return to their seats, one of the girls named Kang Xiu took out a jade pendant, put it on the table, and said a little shyly : "ChuBrother Chu, can you help me take a look at this jade pendant? " "Huh! The little fat girl let out a light sigh and said, "Isn't this the jade pendant you always wear, Xiuxiu?" " "Um! Kang Xiu nodded slightly and said, "I want Brother Chu to see if it's worth anything. If it's worth anything, I'll sell it." " "Youhey! "The little fat girl knew the situation of Kang Xiu's family. Although she knew that she liked this jade pendant very much, she sighed and said nothing. "This Kang Xiu girl, Chu Chen knew by looking at her clothes that her family background might be It¡¯s not good. Looking at the little fat girl¡¯s hesitant expression, I know that the Kang Xiu family must be in trouble. But after all, I am not familiar with her, so the only thing I can do is help her identify it seriously. When Chu Chen took the jade pendant in his hand, his eyes suddenly lit up and he couldn't help but admired it, "What a good thing! " What Chu Chen holds in his hand is a carefully carved jade pendant. The jade pendant is oval in shape and carved on both sides. One side is engraved with the four words "Qing Qin Qin Shen Ren" in low relief, and the other side is engraved with an inscription: "The ancients said that for the senses, Qing Qin Qin Ren and Qing Qin Ren are the most powerful. Adding the word "forbearance" means "what is the matter?", Yu uses these four words to consolidate the key to governing the people, and is a model of truth and practice. The story is inscribed with "self-examination" and "Ming Qian Jiang Yi title". The surrounding is decorated with dragon patterns, and the jade plaque There is a round hole for wearing with a string. The jade pendant should be carefully carved from the finest mutton-fat white jade. The jade is warm and crystal-clear, smooth and white with no blemishes. The pattern has smooth lines and natural turns. It can be described as exquisite workmanship, delicate and moist, and the pattern is beautiful. It is exquisite and has the style of a typical palace manufacturing office. It is a model of perfect workmanship. ¡°Brother, what do these four words on the jade pendant mean? "Chu Yulan asked curiously. Chu Chen explained with a smile: "??It is called "being diligent, cautious and tolerant", which refers to an attitude towards life. Qing represents a kind of taste, a cup of clear tea, a clear breeze and a bright moon, a pure mind and few desires. Prudence represents a kind of moral character, being cautious in independence, careful in beginning, careful in ending, and not deceiving one's heart. Diligence represents a kind of character, diligence is self-motivated, diligence can make up for one's weakness, and diligence is thrifty to start a business. Forbearance represents a kind of character. Only those who have the world in mind can do everything in the world. They can endure hardships and hardships and accomplish everything. "
