Looking at the problem of amber has been confused with purple light
In the amber industry, people who see amber on the trading counter usually use a purple flashlight to illuminate the amber. What they think is what they do, but it is a way to identify amber. However, there are a few problems here that everyone has been confused. The first question: Is it not amber without fluorescence? To judge this situation, one must observe whether the object itself has a thick oxide layer and an ore wrap layer. Because amber has a long time of oxidation, the surface oxidation of the body is more serious, and the fluorescence reaction is weak and weak. If a thicker ore layer is wrapped, there is almost no fluorescence reaction. In the case of this situation, the easiest and most straightforward way is to properly polish the skin, expose the body wrapped in the oxide layer, and then use the violet light to make it easier to judge. In other words, if the surface of the object to be measured is smooth and clean, and there is no excessive oxidation, the fluorescence reaction is certain. If there is no fluorescence reaction, it must be plastic. The second question: How to use a purple light to distinguish whether it is amber, rosin or coba. 1. The fluorescence reaction of rosin is dark green and the fluorescence reaction is weak. 2, the natural amber fluorescence reaction is relatively strong, such as the light green fluorescence of Haipo, the blue fluorescence of the mineral. 3, Coba according to the origin of the same, there is almost the same fluorescence reaction with amber, the age of the material between the Coba and amber, the fluorescence reaction is basically the same as amber, can not see much difference. But there is no pure Coba material to compare, so I can not give you advice, welcome senior friends to provide answers. The third question: how to use the purple light to judge the origin of amber. 1. The “Haiper†produced by the countries along the Baltic Sea, which is what we call “beeswax†in China, polished the peeled ore and the finished product, and the fluorescence reaction is pale green. 2, Dominica's amber mainly has gold green, blue and green, blue sky and so on, to judge their differences need to be used in such cases as black, white, light, etc., using daylight, white light tube to refer to judgment, simple It is not easy to distinguish only the violet light. Among them, the blue sky light fluorescence reaction is blue-white, the white light is white, and the fluorescent blue is bright. The finished product with clear material will have a slight green light on the edge, which will vary according to the color and impurity content of the material. The fluorescence of blue-green and gold-green is also blue-white, but the blue fluorescence is darker than the sky blue. The blue fluorescence of Golden Green is lighter than the first two. 3. The amber of Mexico is mainly composed of gold green and blue-green, and the fluorescence reaction is basically similar to that of rice. It is rare to see the beauty of the blue sky with the blue sky. 4, Myanmar amber varieties, Jinpo, Jin Lanpo and other relatively clear and beautiful materials, the fluorescence response is dark blue, compared to Domi and Mexico's Jinpo, Golden Green, blue is very thorough, As long as a comparison, it is easy to distinguish. Brown red, blood, etc., the fluorescence reaction of the material in my hand is dark green. I have less personal contact with other breeds and cannot provide more advice. Welcome to add and advise. Burmese willow 5, Fushun amber market on the replacement of more varieties, the real goods are less, the fluorescence reaction is dark green. The fourth question: How to use the purple light to determine whether amber is optimized for suppression. There are many kinds of optimization techniques, so I will not list them one by one. I need to grasp a skill. Basically, there is no big problem. The key is to observe and judge carefully. The optimized amber will weaken the fluorescence response. The deeper the optimization, the weaker the fluorescence will be until it disappears. For example, Haiper, not optimized, the fluorescence reaction is very light green, translucent and translucent. After the mild optimization of the pressing technology, if you do not compare it with the unoptimized raw ore, you can hardly see much difference. But a comparison is obviously weaker than the unoptimized material. Deeply optimized, and the color and color of the Haiper, the fluorescence reaction will turn dark green, the difference is obvious. In addition, the violet light can be used to observe whether the flow pattern of amber is normal. The pressed material can be observed through the violet light. It can see the regular block-like joint surface, no pressed amber, the flow pattern is natural and smooth, and there will be a natural bending. radian. This requires more contrast observation and accumulation of experience, and it is not easy to express it simply by using words.
