Gold jewelry contains gold. When gold encounters mercury, it will respond to each other to generate a "gold -mercury agent", that is, it becomes "golden mercury containing gold", and the color is white. There are many types of cosmetics nowadays. Some cosmetics contain trace mercury. When using cosmetics, accidentally encounter gold jewelry, which will turn white and generate "golden mercury with gold". The agent contains a trace lead, and the gold encounters the lead capacity. For the above two gold jewelry that has become white and black, it can be heated with the gasoline spray wheels used for jewelry processing, because the melting point of mercury and lead is very low. In the heating of the spray wheel, it will volatilize, so that the gold jewelry will restore the gold jewelry. face. Of course, it is best not to wear gold jewelry when applying cosmetics or dyeing to avoid post -troubles. If someone wears a golden ring on a finger on the same hand, and wearing a platinum ring on the adjacent fingers, because the fingers are often moving, it is easy to cause the golden ring and platinum ring. Platinum white hair. In this case, it cannot be used to disappear with gasoline spray wheels, because the melting point of platinum is hundreds of hundreds of hundreds of more than the melting point of gold. For such a white gold jewelry, you can use agate knife planing, or rub it with thick cloth (such as canvas) to restore the gold to brighten. For 18KCTP jewelry like the appearance and gold jewelry, the interior is generally copper or copper gold with gold, and the appearance of gold plating a layer of gold. After using it for a period of time, the local forging layer of the ground may be grinded or falling off. Or copper alloy, it is easy to be oxidized or chemically reacts with the air in the air. 18KCTP forging golden layers of mercury is backward and black, and it generally cannot restore it to the original golden yellow, unless it is once again for electrical forging technology. The local turning of the gold necklace is mainly at the connection between the ring and the ring. Because the ring and the ring side of the necklace requires welding, welding medicines need to be welded during welding. Each manufacturer's use of welding drugs is not necessarily the same. Some welding medicines are not high in gold. After soaking, black phenomenon will occur. Some people who replaced the old -fashioned person said that the necklace I handed to them was golden yellow, and there were many small black spots when they were returned to me. This is exactly the saying that "real gold is not afraid of fire refining". After the treatment of the gold, it is still the original golden yellow, which shows that the gold content is insufficient when welding. There is generally no good way to restore the golden yellow caused by the black caused by welding, unless the entire necklace is forged.
