Distinguishing original gold from imitation 3
Identifying real gold with water
The easiest and cheapest way to distinguish gold from other metals is to use water. In this method of identifying gold, you can throw your jewelry in water, if the gold remains on the bottom of the container and does not float, you can be sure that your gold is genuine.
Real gold detection with Vitex
Another way to distinguish gold from rhinestones is to use Vitex. Of course, before explaining this method, it should be mentioned that detecting gold with Vitex causes corrosion in gold. Therefore, it is not recommended to use this method. To do this method, it is enough to pour a very small amount of Vitex on the gold. If you notice the color of the metal changing to red, green or brown, your gold is genuine; But if the desired metal turns black, it indicates that it is fake.
Detection of real gold with iodine
You can check the authenticity of gold with iodine. Apply a little iodine on the surface of the gold, if the trace remains, the gold is fake. But if it is lost, your jewelry is original. If you put a drop of iodine on platinum and it leaves a dark mark, the darker the platinum, the purer it is..
Identifying real gold with ice
Gold and silver are very strong conductors of heat compared to other metals. If you put your gold and silver on a piece of ice, the melting speed of the ice will increase so that you think you have placed a hot object on it, so you can use this method to identify the original gold and silver.
Identification of real gold by weighing
If you have recently bought a gold bar, but you are worried that you have bought fake gold instead of real gold, you can weigh it to find out. First, put the ingot on an accurate scale and measure its weight. Then fill a container with water, place it on the scale and set the weight indicator to zero. Immerse the ingot completely in the water and weigh it again. To find out, just divide the first number by the second number. If the obtained figure is 32.19, you have bought pure gold.
Detection of real gold with nitric acid
A definitive method for detecting gold is the use of nitric acid. Place your jewelry in a stainless steel container. Pour a drop of nitric acid on it, if they do not react with each other, your gold is genuine. But if the color of the drop of nitric acid turns green or brown due to the reaction, your gold is fake. Note that nitric acid damages your jewelry. In addition, because nitric acid is dangerous, it is better to leave this to an experienced goldsmith.
Detection of real gold with alcohol
Alcohol is one way to distinguish real gold from fake. Gold detection with alcohol is another widely used home method to check the authenticity of purchased gold. Most metals change color in the presence of alcohol; For this reason, when buying replacement jewelry, the buyer is asked to keep these jewelry away from alcohol and water in order to prevent the color change and deterioration of the appearance of these rhinestones. For this reason, you can use the method of detecting gold with alcohol to find out whether your metal piece is genuine or fake.
In the gold test with alcohol, you can dip part or all of your metal piece in alcohol. Since alcohol vaporizes in the presence of air, you only need to spray a small amount of alcohol on the metal piece and you do not need to immerse the metal in alcohol. If you plan to immerse the piece in alcohol to be sure, you should use a closed container.
If you use immersion method and only 5 minutes is enough to detect gold with alcohol. If after 5 minutes your metal does not change color and does not turn black, it is original; But in the spraying method, you should spray some alcohol to the metal piece at least two to three times at different time intervals. After a day, if no color change is observed, you can be sure that the gold is original.
