2. Take a small amount of powder and rub it directly onto the aluminum sheet. After one minute, the white piece will grow 1-5 mm long white hair, which can be judged as genuine. Counterfeit goods have no such reaction.
Note: This can only be qualitative, but not quantitative.
Third, the simple physical identification method:
1. Take 3g powder piled on the iron piece, slowly heat it from below with fire, it will gradually turn black, and it will be judged to be real if it is turned cold after being cold. Otherwise it is false.

True, anyone with white, black, yellow, gray and other variegated colors is impure or doped. At the same time, it can also judge what is contained in the material according to the amount of its variegated color, and at the same time, it can determine the approximate content of its impurities. This is one of the easiest and most effective methods.
