To judge this situation, we should first observe whether the object itself has a thick oxide layer and ore coating, because if amber is seriously oxidized on the surface for a long time, the fluorescence reaction will be weak, and if it is coated with a thick ore layer, there will be almost no fluorescence reaction. In this case, the simplest and most direct method is to properly polish the epidermis to expose the absorber wrapped by the oxide layer, and then irradiate it with purple light, which will make it easier to judge. In other words, if the surface of the measured object is smooth and clean, and there is no excessive oxidation, then the fluorescence reaction will definitely occur. If there is no fluorescent reaction, it must be plastic.

(Burmese amber is skinned, and the part of the side that is not completely peeled off has no fluorescence.)

Two: How does Ziguang distinguish amber, rosin or Coba?

1, the fluorescence reaction of rosin is dark green, and the fluorescence reaction is weak.

2. The fluorescence reaction of natural amber is relatively strong, such as the light green fluorescence of Haiper and the blue fluorescence of Miner.

3. Most of Coba have no fluorescence reaction.

How to judge the origin of amber with purple light?

1, "Haiper" produced in Baltic countries, also called "beeswax" in China, has a light green fluorescence reaction in polished and peeled raw ore and newly processed finished products.

(On the left is the fluorescence of Baltic amber, and on the right is the blue-white fluorescence of Burmese amber. )

2. Amber in Dominica mainly includes golden green amber, blue green amber and sky blue amber. To judge the difference between them, it is necessary to use sunlight and white flashlight for reference judgment under the conditions of black background, white background and light transmission. It is not easy to distinguish pure amber from pure amber by purple light alone. Among them, the blue-blue pearl in the sky has a blue-white fluorescence reaction, white light shines in blue, and the fluorescence is blue and bright. The finished product with clear material will have a faint green light on the edge, which varies according to the color and impurity content of the material. Blue-green amber and gold-green amber have blue-white fluorescence, but blue fluorescence is darker than sky blue. Compared with the first two, the blue fluorescence of golden green amber is lighter.

3. Amber in Mexico is mainly in golden green and blue-green, and its fluorescence reaction is basically similar to Domi's. It is rare to find a material comparable to Domi Sky Blue Pearl.

There are many kinds of amber in Myanmar. Generally speaking, Burmese amber, such as brown amber, Jin Po, golden blue amber, etc. There is a blue-white fluorescence reaction. Compared with Domi, Mexican Jin Po and Golden Green Amber, it is completely blue, and it is easy to distinguish as long as it is compared. The fluorescence reaction of Burmese blood amber is dark green.

(Myanmar amber brown pearl willow blue fluorescence)

(Burmese blood beads are fluorescent, the higher part of the carving is dark green, and the polished part is blue and white)

5. There are many substitutes in Fushun amber market, and the fluorescence reaction is dark green.

Four: How to judge whether amber is optimally inhibited by purple light?

At present, the optimization technology of amber is getting higher and higher, and some optimized amber will have fluorescence reaction. The key to distinguish whether to optimize suppression lies in careful observation and judgment. The optimized amber will weaken the fluorescence reaction. The deeper the optimization, the weaker the fluorescence until it disappears.

For example, Harper is not optimized, and the fluorescence reaction is obviously light green, bright and translucent. After the compaction process is slightly optimized, if it is not compared with the unoptimized raw ore, there is hardly any difference. But in contrast, it is obviously weaker than the material without optimization. Deep optimization, Harper baking and pressing, fluorescence reaction disappeared, and the difference was obvious.

In addition, purple light can be used to carefully observe whether the flow pattern of amber is normal. When observing the pressing material with purple light, you can see the regular block joint surface. Amber without embossing, the flow pattern is natural and smooth, and there will be a natural bending curvature. This requires more comparative observation and experience accumulation, which is not simply expressed in words.

Many bar friends who bought a purple flashlight in a treasure have the following doubts-why is it really amber, the purple I bought before?

What should I do if the flashlight can't emit fluorescence? Why is it obviously a fake jade treated with glue, but it has no fluorescence? Why is most amber white to me?

There is no fluorescence in the sky, so you can see some faint fluorescence at night.

.

I'll tell you why-because you bought the wrong flashlight, not a professional appraisal flashlight, and the fluorescence is too weak! Or it's not really 365 purple light, or it's just an ordinary blue light bulb, not purple light! At present, the purple hand in China

Most electrical appliance manufacturers pretend to be professional jewelry and jade appraisers with extremely low-cost flashlights.

Electricity, it's ok to take photos of cosmetics. It's amateur to distinguish the authenticity of jewelry and jade from the fake way! ! !

Violet flashlight is necessary, but this kind of flashlight in China is either toy type and not used at all. I have devoted myself to doing a lot of research in this field.

Through comparison, it is found that our domestic violet flashlight wick technology lags far behind Europe and America, and now more than 90% of the products on the market are technologies eliminated by others more than ten years ago.

Surgery. Violet flashlight is a new product of China people. There are not many buyers and friends who know how to do it online. As long as the flashlight can shine, it will give a big compliment, which is really deep.

When I got to know it, I found it was not like this.

.

Let's analyze what kinds of purple flashlights are currently on the market.

The first type of toy, which is also the worst, is the one with several domestic diodes and small wicks in the lamp holder. Just put a No.5 dry battery.

It's very bright, ten or twenty dollars. This can only be said to be a toy shape, and it is good to be able to identify cosmetics. Scrapped in June+10-February, 5438.

The second kind, the gold shell of local tyrants in their 40s and 50s, is very beautiful. Contrast pictures of lighting effects.

It is also obvious, but the actual effect is less than one third! Typical strong light flashlight small manufacturers, assembled flashlights, only need very low cost, can be lit.

All right. This kind of photo is ok for ordinary cosmetics in China, but not for many foreign brands of cosmetics (some foreign manufacturers will take fluorescent products)

The agent's cosmetics have been specially treated to weaken the fluorescence), but it is very amateur to identify amber, jade and jade, and can identify the feeling of 10%.

The situation is excellent.

.

The third one is a single-core violet flashlight, the price is 120- 130 yuan, and it doesn't have focusing function. Don't buy this kind of cheating.
