1. Do not contact its volatile chemicals. There are rust spots in gold bars, golden turns, and black. Black turning is caused by copper and silver in the gold bars after a chemical reaction is generated and generated by copper sulfide and chlorine, while the white transformer is caused by the contact with the mercury (mercury) vapor in gold. Once consumers wearing gold jewelry went to the hospital to see a doctor, and accidentally broke the body thermostat. As a result, the jewelry became white after contact with mercury. 2. Gold should be stored in dark and dry places, away from the kitchen, toilet, etc. there will be polluted rooms. In addition, there is no need to deliberately prevent moisture -proof, because the moisture -proof agent is volatile, and it is easy to produce chemical reactions after contact with gold. 3, purchase and storage ideas to ensure that you do not lose weight. Mainly cannot bump. Gold is relatively stable and basically does not oxidize, but it is relatively soft. The quality in bumps is easy to lose. The expansion information: The physical properties of gold: 1, color: The steam emitted when gold is melted is green; its gold powder is usually brown during the smelting process; If it is cast into a thin piece, it can also transmit green light. 2, ductility: is extremely strong. 1 ounce of gold can be pulled into 50 miles long, and its ductility makes it easy to cast and is a good choice for making jewelry. Gold is the strongest in the metal. 3, forgedness: INO. It can cause extremely thin and easy to roll up. 1 ounce of gold can be hammered to 4 million -foot thick and 100 square feet. The ancients hammed it into thin slices to decorate the temples and the palace. These can explain the strong flexibility and forgedness of gold. Reference materials Source: Baidu Encyclopedia-Gold
If you want to repurchase the gold bars, it is best not to disassemble and seal it, which will help keep it; if you disassemble the plastic seal, just do not touch it, because sweating in summer, sweat will have a certain corrosion effect on gold, sweat will have a certain corrosion effect on gold. For example, red dots may appear on the surface of the gold, that is, "long spots", which affects the aesthetics. The gold bars should not be bumped, because the purity of many gold bars is now 4 9, which is relatively soft and easy to touch a pit. As for gold jewelry, you should also pay attention to prevent sweat and acid -alkali corrosion. Now many gold brands provide free cleaning and maintenance. If you do n’t wear it for a long time, you can get it in the store for maintenance before storing. If the real gold darkening is caused by the genetic reactions contained in it and the silver reactions, which generate copper sulfide and chlorine chlorine, and the whiteness is caused by the contact with the contact of the mercury (mercury) steam.
Avoid bumps and squeeze when storage. At the same time, the gold bars sold by general banks are well -packed in hard and hard plastic. The bank is required to be intact when purchasing back. Trading. It is recommended that customers purchase the packaging box provided by the bank, or open a storage box in the bank for storage.

Just put it in cloth bags, golden stability is very good, and it will not deteriorate for many years. But do not contact other metals for a long time.
