How to identify the method and skills of pure gold

As a precious precious metal, gold has always been favored by people.However, there are also many inferior or mixed with other metal counterfeit products on the market.Therefore, it is very important to correctly identify pure gold.The following will introduce several methods and techniques to help you identify authentic gold.

Visual inspection

First of all, appearance inspection is one of the simplest and most basic methods.Pure gold has unique appearance characteristics: bright and uniform color, soft luster and not easy to rust.If the surface is found in the surface of oxidation or the color is uneven, it may be doped by other materials or alloys.

Chemical reagent test

Secondly, you can use chemical reagent tests to determine whether it is pure gold.Using a dedicated design to detect the precious metal content, you can know if you contain other materials after adding a small amount of test solution on the sample.

Density measurement

Dean measurement is also one of the commonly used methods to identify authenticity.Because different ingredient alloys have different density, the density can be calculated by determining the density by determining the density by determining the density in the air and water in the air.

X -ray fluorescent spectrometer detection

The X -ray fluorescent spectrometer can quickly and accurately analyze the content of each element in the sample and determine whether it is a pure variety. The equipment is widely used in gemstones, glass and steel industries. It provides a better choice for the jewelry industry.

Summarize:

In summary, when purchasing or holding gold, be sure to pay attention to the above points of identification, and seek professional institutions to further verify and confirm when needed. Ensure your own rights and asset security.
