If you observe with a magnifying glass, you will see more carefully. 2, ancient gold jewelry will not have obvious official purity logos. 3, of course, there will be official signs of counterfeit gold jewelry, so further inspections need to be performed. 4, find obvious discoloration. Check the wear area of the golden surface, which is usually on the edge of the golden products to check the color change there. If the golden color disappears and becomes another color, then this product is just a gold -plated. . The bromine chemistry test 1. Put the golden products into the alcohol solution for a small meeting. 2. Pour a filter paper sperm solution. 3. At this time, the filter paper becomes gray -purple. 4, drop 4 drops of bromo -A reagent to the filter paper, if the filter paper becomes white, then this gold product is real gold. The test time takes 20 minutes. . Magnetic test This is a simple test, but it is not a sufficient proof to prove whether it is true gold. You can find a powerful magnet for testing.
