Golden identification methods are greatly revealed to help you easily distinguish the authenticity

Golden identification method Disposal

Gold has always been a symbol of wealth that people chase, but there are many fake and inferior gold products on the market.Therefore, learning the correct identification method is essential for protecting its own interests.This article will reveal some commonly used golden identification methods to help you easily distinguish the authenticity.

Visual inspection

Appearance inspection is the most basic and most intuitive way of identification.First of all, pay attention to observe whether there are obvious oxide or uneven colors on the surface of the golden surface, which may be caused by other alloys added by counterfeit products.In addition, the real high -purity gold will show bright and uniform colors in light, while counterfeit products may appear dim or gray.

Magnetic test

Gold with high purity and high content is very stable and does not have magnetism. It should be completely unprepared when performing magnetic testing.If you use magnets to attract the so -called "gold" products, it is likely to be mixed with other magnetic substances.

Density

Due to the differences in density in different components and alloys, the ingredients can be preliminarily determined by density determination.Under normal circumstances, the more pure, the higher the density of the gold, and the relatively greater the density.

Chemical reagent test

Chemical reagent tests can help us further confirm whether it is a real pure and pure -no -doping material.Among them, more common chemical trials have strong corrosive substances such as sulfuric acid, iodine, and sodium hydroxide.When the number of reagents is added to the sample, no reaction is generated, it means that the sample contains silver.

If a white precipitation appears on the sample with a nitrate solution, it means that the sample contains silver; if the *** solution is added, the precipitation disappears, which means that there is a copper element; if the sodium sulfur sulfate solution is addedIt means nickel element.

In summary, in daily life, avoid purchasing fake and inferior products to improve its own identification ability, and make comprehensive judgments based on the above four aspects.
