In theory, the color of the gully in the bite has not changed. The higher the goldenness. But we do not recommend this method because this may hurt the teeth. In addition, because lead is softer than gold, bite marks will be left on the gold -plated lead. The second method of 2/3 is the magnetic detection method. Gold is a magnetic metal, so it can be attracted by magnets. This method is simple and easy. Use magnets to suck the golden device. If the magnet can attract gold, it is fake. However, it cannot be attracted by the magnet alone that it cannot prove that this golden device is true, because it may also be made from other non -magnetic metals. The third method of 3/3 is a very professional inspection method. Generally, only jewelry dealers or craftsmen will adopt, that is, nitric acid testing method. Put the gold in a small stainless steel container, drop a drop of nitric acid on the goldware, and observe the reaction. If the acid is green, then this golden device is either made of ordinary metal or gold plated. Then it is gold -plated copper. If there is no response, then this golden device is true.nQuestionnnDoes this look likenAnswer the picture to see if it is truenIt is recommended to burn with firenQuestions, but I can't bite himnAnswer if it will change with fire to see if it will change colornDid you burn?nAnswer that is truenQuestion 18KnHow much is the price of gold now?nAnswer 473 × 18 = 8514n8514 yuannMore 11nBleak
