The influence of gold purity and method of distinguishing
As a valuable metal, gold directly affects its value and use.In the market, how to distinguish the purest gold with a variety of purity has become one of the focus of consumers' attention.This article will discuss the impact of goldenness on strength and the most pure golden method.
1. The impact of goldenness on strength
Gold is a stable chemical properties, not easy to oxidize and corrosion, and has good conductive performance.These characteristics are closely related to their purity.Generally speaking, the higher the purity of gold, the less impurities, and the performance of physical and chemical performance is better.
In the jewelry industry, high purity (such as 24K) gold is usually used to make exquisite jewelry, because they have unique luster and color, and it is not easy to cause skin allergies.The industrial field is more inclined to use composite materials with low -quality (such as 18K or 14K) to balance cost and practicality.
2. Differentiated the purest golden method
a. Observe color:
The higher the gold color of the golden color, the closer it is, the higher the golden color, and the light shades are even closer and bright; and the low grade may show green or white.
b. Test with acid solution:
Drop a small acid solution on the detection object and observe the reaction to distinguish the authenticity.Because the real 24K yellow will resist the erosion such as nitric acid, it can be preliminarily determined whether it is authentic in this way.
c. Find trademark certification:
When buying, check whether the product is marked with the corresponding manufacturer information, commodity numbers, and national certification signs. These are all necessary conditions for ensuring the regular and reliable process of the product.
