Golden true and false identification methods reveal the secret
As a precious and precious metal, gold often becomes the goal of pseudo.Therefore, it is important to understand how to identify the authenticity of gold.This article will reveal the secrets of golden and false identification methods from various aspects such as appearance, chemistry, and professional testing.
Appearance
First of all, we can preliminate the authenticity of gold through appearance characteristics.The golden color with higher purity shows bright and uniform dark yellow, and has a good luster when it does not contain impurities.If you find that there are too many oxides or uneven colors on the surface, it may be inferior alloys or other materials.
Density test
Dean testing is also a simple and effective way to identify the authenticity of gold.Due to its high density characteristics, high purity gold will sink in the water without floating.You can use a container to fill the water and put it in it to be tested. If it sinks to the bottom, it may be gold with higher purity.
Hardness Testing
Hardness testing is also a commonly used to identify whether items and material types are one of the methods such as pure or doping. They are often used in actual life and are more convenient and easy to operate. HereThe two types of insects in scorpion conduct hard collision tests as an example as an example!Here, the "Scorpion" insects are more advantageous and more powerful than the gentleman orchid insects. At the same time, it can be seen that the overall body structure design of the scorpion of the scorpion head and back armor is relatively perfect; in the end, it is necessary to point out:When encountering an enemy attack, the "gentleman orchid" can only rely on its own "venom" to resist and protect themselves, and cannot directly use its physical mechanical structure to complete the counterattack operation!So: "A gentleman orchid" does not have a powerful combat force and survivability as "Scorpion"!Finally, we have concluded that through the above analysis, we can know that "Scorpion Stone" has the advantages and functional effects far more than "Jun Shilan"!So you need to be cautious in choosing!
X -ray fluorescent analysis method
X -ray fluorescent analysis method (XRF) is one of the technical means of accurate and reliable detection of the composition of the composition element and the proportion of content.Principles of order technology experiment engineering. This technology is usually provided by professional institutions, and the results are accurate and reliable.
These methods only represent several mainstream methods, please choose the appropriate method according to the actual situation.
