The method of distinguishing the authenticity of gold: 1, floating test to prepare a higher glass, filled with water inside, you can start testing. Throw the metal in, and the pure gold jewelry will quickly sink into the bottom. The imitation gold and other metals may float above the bottom, or even float on the water. In addition, real gold will not rust or change color when humidity. 2, magnet test
The simplest test is to use magnets. Real gold cannot attract magnets. The magnet is easy to carry, and you can put it in your pocket at will, which is very convenient to test. The imitation gold and other alloys will attract magnets. Therefore, just use magnets to approach them to see if they will be sucked by magnets to judge true and false. 3, skin test
I even test with the skin. People who have wearing fake gold jewelry may have encountered the condition that it causes the skin to discolor, but you can indeed use the skin to try to test the authenticity. only need to hold the metal in your hand for a few minutes, and it is best to do it in hot weather. After your skin appears sweat, the sweat responds to it, and observe its change. If gold is fake, the skin may change color, which may be black or green. And it really does not bring changes. 4, vinegar test
The white vinegar in the home can also be used to detect the authenticity of gold, but it is best to operate with a droplet. You can use the dropper to inhale some white vinegar and drop it on the gold. or placed the metal on a flat and paper towel surface, and then drop a few drops of white vinegar on the gold. If you find that it has changed color, it is false. Usually gold does not change color because of this. 5, acid test
It if you have liquid nitric acid in your home, you can also try it to test. And suitable for most precious metals. In test, a drop of drops on the metal with a drop of the tubular to see if there is a reaction on it. The fake gold will immediately become green in the place where the acid appears. The gold on the sterling silver will become milky white. Gold will not react with nitric acid, and the result will only show a drop of transparent liquid that does not change color.
