To identify whether the agate has been injected with glue, you can start from the following aspects:
1. Observe the appearance.
Injected agate usually has a smooth surface with no noticeable natural texture and uneven color. This is because the injection fills the cracks and crevices inside the agate, making the surface flatter. However, if you look closely, you may find some tiny bubbles or impurities that cannot be avoided during the dispensing process.
2. Hot needle test.
The hot needle test is a simple and practical method of identification. Gently touch the surface of the agate with a hot needle, if the glue is injected, the glue will overflow and give off a pungent odor. This is because the hot needle heating softens the glue, which exposes the fact of the glue.
3. Ultraviolet test.
Ultraviolet testing is another effective method of identification. Under ultraviolet light, the glued-filled agate may fluoresce, as the fluorescent agent in the glue glows brightly when exposed to ultraviolet light. Natural agate, on the other hand, does not usually fluoresce under ultraviolet light.
Fourth, density test.
Density testing is also a commonly used identification method. Since glue injection changes the density of agate, the density of agate can be calculated by measuring its weight and size. If the density is abnormally high or low, it may indicate that the agate has been dispensed.
5. Chemical reagent testing.
Chemical testing is a more accurate method. Specific chemical reagents are used to drop on the surface of the agate, and if an injection is present, the reagent reacts with the glue, resulting in a color change or other visible signs. This method requires certain professional knowledge and operational skills, so it is recommended to do it under the guidance of a professional.
In conclusion, identifying whether agate has undergone glue injection treatment requires comprehensive consideration of many aspects. By observing the appearance, hot needle test, ultraviolet test, density test and chemical reagent test, it can be more accurately judged whether the agate has been injected with glue. For consumers, they should be vigilant when buying agate products, choose reputable merchants and carefully check the quality and authenticity of the products. At the same time, it is also very necessary to understand and learn the method of identifying the injection of agate to avoid being deceived.
