Lao Temple Gold and True False Differential: Judgment of Pure and Reality
As a traditional jewelry material, the old temple gold has a long history and unique cultural value.However, there are many fake and shoddy products in the market.To distinguish the purity and authenticity of the golden temple gold, you need to master some professional knowledge and skills.
external assessment
The appearance is one of the most intuitive judgment criteria.First of all, pay attention to observe whether the surface of the old temple's gold jewelry is smooth and smooth, and there are oxygen dioxide or wear marks.At the same time, pay attention to whether the color is uniform and bright.
Weight test
By weighing, you can initially understand the density of the old temple's gold jewelry.Generally speaking, the more heavier it means at the same volume, the higher the gold content.However, it should be noted that there are also increased weight in the market to simulate high gold content.
Chemical reagent detection
The use of chemical reagents for testing is one of the more accurate and reliable methods.The samples can be tested by the Garli reagent, the Marquan reagent, etc., and the color changes are generated after reaction to the different components to infer the gold content.
X -ray fluorescent analysis
X -ray fluorescent analysis is currently the most commonly used in the jewelry industry to quickly and accurately determine one of the technical means of its ingredients and content proportions. Through X -ray incident samples, fluorescence phenomena will occur when X -rays interact with the nucleus.Obtain elemental information based on the absorption capacity.
The above is the introduction of how to judge the goldenness and authenticity of the old temple, I hope it will be helpful to you!
