More experimental products were used, including Dominican, Liaoning, Baltic amber, Colombian coba, natural amber powder and other synthetic pseudo amber. I have already marked the texture of the various materials, and now I will experiment with them to prove them.
Actual combat 1: salt water experiment
This experiment is the main method of identification. Due to the light specific gravity of natural amber, it should float on the water in 1 (salt): 4 (water) brine. As shown in the figure below, the standard 1:4 salt water is calm in the clear water. When the salt is added, some of the experimental products float up.
Actual combat 2: fire experiment
This experiment is not destructive, and its main purpose is to smell. I only burned the stuff that floated up in the last salt test. The fire is used in the ordinary lighter, the stay time is 4-5 seconds, and each of the upper and lower frames is a group. It can be clearly seen from the figure that the coca-broiled fat of Colombia and the natural amber powder are left behind. Obvious traces, similar to broken rice. I can't show it with the taste, just describe it: two pieces of the Baltic Sea - a slightly thick and loose smelly road, Liaoning, China - rosin mixed with charcoal, Dominican - very light fragrance, amber powder Press-fit--mix the chemical flavor of the pine flavor. After the polished natural amber beads are fired for 4-5 seconds, the surface will become deeper but there is no hole-like peeling feeling (I can think of a better description of my modification).
Actual combat three: electrostatic experiment
This experiment was not based on the first two experiments. The results of the experiment showed that all the materials used had electrostatic reactions. This experiment can only distinguish the glass, because the glass usually has no static electricity after rubbing.
Actual combat four: washing nail water (ether experiment)
The cheapest manicure lotion is used, which is sold in many places. The first few experiments of rosin in this experiment forgot to take pictures: P except the first vertical row is all three groups, the first one is painted, the second one is staying, and the third one is completely evaporated. Colombian coba and rosin are apparently slow to volatilize, and they are clearly sticky at the point of hand rubbing and can leave fingerprints.
Actual combat five: ultraviolet radiation
Take the UV test machine and try it out, so only the flat ones participated. Polished natural, amber powder pressed, coba and rosin have discoloration, the plastic has a slight change on the top, the synthesis does not basically change color. Recently, the fake green scorpion bought from the outside, except for the white eccentric scales, also changed color under ultraviolet light. It is not a deep understanding of amber, and it will not see the true and false.
to sum up:
The simplest experiment at home is the above. Basically, other methods of removing the fire will cause the fish to leak. The salt water experiment can only be the uninlaid object. The static electricity can only exclude the glass. The nail water is useless for plastics and synthetic compacts. It doesn't have much use for high imitation and pressing (unless you have seen a lot to judge by the color depth); fire is the most obvious, but it will cause damage to the real thing, and the real natural amber taste can not be said, and amber A glazing agent that may be present may also have a pungent taste. The actual combat article can show the results of the same experiment of multiple materials, and the final identification still requires a large amount of experience accumulation and reading of the correct relevant literature.
