As a precious precious metal, gold has always been loved by people.However, there are also many fake and shoddy gold products on the market.Therefore, it is very important to learn to distinguish the authenticity of gold.This article will introduce several common gold authentic identification skills to help everyone better identify real gold.
Appearance inspection is the most basic and most intuitive way of distinguishing.First of all, pay attention to observe whether the gold surface is aerobic or rust, because the gold with high purity will not rust; secondly, it depends on the color and luster. The real high -purity gold should show bright and uniform color and luster;Gently draw on the surface with nails, and if you leave traces, it is likely to be counterfeit products.
The hardness test is to determine whether the item is a gold with high purity.Generally, simple tools such as keys or coins can be used for testing. Gently scrape the items waiting to be tested on the surface of a flat and clean scratch without scratches. It can be determined that it is high.
Density measurement is also an effective local method to identify the degree of purity, the higher the pureness, the greater the dense force. You can put a known weight in the water and determine the proportion of the proportion of the ingredient.After the displacement, it is not dense enough. On the contrary, if it sinks to the bottom and stops moving, then this sample may contain many materials.
X attempts the fluorescent analysis method to send the x attempt fluorescent beam to scan through the x attempt fluorescent instrument to scan the measurement, and to the energy spectrum information based on the feedback of the measured object to infer the information and other information of its composition and content.This technology has gradually been widely used in various chemical, construction, environmental monitoring industries and other fields, and has achieved significant results in many industries.
The four methods introduced above can effectively help us identify and distinguish between high -quality and subtle products between the sub -goods but it are very important.
Only by ensuring that you can buy high -quality goods can you avoid the loss caused by various sellers to provide false information.
