Jewelry Merchants Network reveals fake amber beeswax

The identification of amber has been one of the problems in the detection industry in recent years. The following is a more understanding of the practice of amber wax in the GTC Center during the testing process. Share it with you here:

First, suppress amber:

We all know that the purpose of pressing is to artificially fuse the corners of amber to give an impression of the overall appearance. The processing plant we visited, pressing amber has two purposes: one is the traditional purpose, using pressed amber to imitate natural amber; the other is the purpose of beauty, with different colors of amber to suppress, giving people a colorful feeling.

In the past, when we identified pressed amber, we checked whether there was a "red grain" effect. During the visit, we found that when the first purpose is to suppress amber, the processing plant will first polish the small crumbs of amber, remove the slightly darker surface, and then press it, so that the red grain in the amber The effect is not obvious. Everyone must be careful about the amber that is pressed in the identification. (Many people can't distinguish between amber and Burmese amber: the red-grain effect is. Generally used, the amber recycling machine melts and suppresses)

Second, "painting" amber:

In the daily inspection, we have found that some amber surfaces are covered with a layer of maroon or black film. The owner of the processing factory interprets this method as “painting”. The main purpose is two: one is to spray at the bottom of the carving. Apply a layer of paint and then engrave the bottom. After engraving, the light yellow of amber itself contrasts with the maroon of the paint layer to create the layering and effect of the engraving; or let the “sun light” in the amber paint the color at the bottom. The background is more obvious and beautiful. The second is to prevent the amber "aging" and "component volatilization", spray a layer of paint on the surface of the finished amber.

In the national standard GB/T16552 "Jewelry and Jade Name", we can see that the listed jade stones such as diamonds, emeralds, jade and other mulched films are included in the "treatment" range, although there is no amber The film is defined, but we must pay attention to whether the amber has been treated like this. (Because the film amber is also included in the treatment.)

Third, "baked" amber:

The national standard GB/T16552 "Jewelry and Jade Name" clearly stipulates that amber is deepened by heat treatment and is an "optimization". The processing plant bakes amber in the oven at a given temperature. The yellow amber can be baked into a brownish red (skin), which can be baked into "old beeswax". After the heat treatment of the amber, the bubbles can all burst. At a certain temperature, the "sun rays" generated by the bursting can also turn brownish red. The processing plant will polish the amber brownish-red skin, and the brownish red disk will be shaped. The cracks are highlighted in the middle of the yellow amber, very beautiful. (Someone will ask how to bake, nowadays generally use a professional amber optimized furnace for homework)
