Because of the nature of the work, the author touched a lot of crystal lamps. For crystal, the best place to produce is in Egypt. The price of Egyptian crystal is much more expensive than domestic crystal. So how do you judge the domestic crystal and the Egyptian crystal? The so-called import and domestically divided points actually refer to the difference in crystal. In fact, the crystal lamp, the import is definitely better than the domestic one, but it is also several times more expensive. If you can buy real imports, the money is worth more. If you buy a domestic lamp and import the money, it will be too embarrassing. The difference between imported and domestic crystal lamps: 1. Listen to the sound. Look for a piece of light, gently sway the suspended crystal, and listen to the sound of the collision between the crystals. The collision sound of the imported crystal is crisp, and the sound of the domestic crystal is not crisp. 2, weight identification. Find a large crystal ball, hand rubbing weight, generally imported than the domestic sink. (It's generally useless. How do you know that two are imported ones made in China?) 3. Form discrimination. There are three kinds of crystal shapes on the market: spherical, drop-shaped and rectangular. These three are also the main domestic crystal shapes. In addition to the above three types of imported crystals, the style is more diverse, and the cutting process is also better than domestically produced. 4, (the most important point, let the domestic crystal a trick "death" method) to see the cutting of the perforation. This is the most accurate! Directly look at the position of the perforation of the crystal root, the perforation of the imported crystal is cut perfectly, even if the quality is good, the incision will be flawed. (Imported and transparent, the domestically produced can see the effect of matte, there will be no transparent effect) Imported perforations! Domestic piercing! 5, look at the corners and corners of the cutting surface and the face is not right, it is difficult to distinguish between the edges and corners, some of the seemingly smooth cut surface will be known to be domestically produced! 6, color. In fact, at first glance, there is not much difference. Look closely, you will find that the color of the Egyptian crystal is very positive, the most obvious is that under the light it will have a colorful light, reflected to the floor can see very beautiful colorful light. The domestic crystals will not, they have a lot of color, but there will be no eye-catching colorful light. 7, purity. As the name suggests, you take a closer look at your hand, even if you don't know what is Egyptian crystal or what is domestic crystal, you can see which one is more transparent and which is more exquisite. Good things always stand the test. 8, say the domestic crystal, there are three or six points and so on. The best domestic crystals can be compared with imported crystals, but there will be no colorful light. Medium-sized domestic crystals are acceptable prices and qualities in the general Chinese market. The next three levels of crystal are not much different from glass beads. 9, the test of time. Imported crystal hangs for a long time, as long as it is dusted with cotton cloth, it will be as bright as new, and the domestic crystal will become dull and dull after a long time! Crystal is easy to dust, it is best to use pure cotton cloth, if the hair removal cloth is equal to no wipe! Crystal maintenance is more elegant. The crystal is very hard, very brittle, and it is easy to break! So be careful when cleaning! It’s not good if you break it!
