    ; Gold (GOLD) is the single -quality form of chemical element (AU). It is a soft, golden, precious metal resistant metal. Gold is one of the rare, precious and extremely valued metals. Internationally, gold is generally based on ounces. In ancient China, "two" as a gold unit, a very important metal.

    three; Jin's simple high temperature will not be eroded by sulfur and oxygen, but under certain conditions, it will be oxidized, or at a high temperature of 4000 degrees, pressurize, and it will be oxygen when there is a catalyst. Very slow response: It can be considered not to react, because there are few flames that can exceed 3500 degrees, and the gold is melted above 1000 degrees, so it is generally considered that the real gold is not afraid of fire, that is, gold does not react with oxygen at high temperature at high temperature. , Gold and sulfur, bromine, iodine, nitrogen reaction temperature is higher, and the temperature of the response temperature with chlorine gas, fluoride, and king water is low.
    four; although the gold itself is not corroded, its chemical affinity with sulfide is very strong, and it is easy to absorb hydrogen sulfide gas in the air. Essence The completion of the production of gold products requires many complex processes.

    This welding of low -colored gold jewelry is basically welded, and the formula of the weld can ensure that the gold content of its jewelry is not lower than the prescribed standards. For example, to welded 14K jewelry, the gold content it used was 58.5%(14K standard gold content), and the remaining 41.5%was low melting point materials. The mixed welds in this way can weld the jewelry and ensure that the gold content of the jewelry is unchanged. However, if you want to prepare pure gold welded, the problem comes, because the gold content of the solder of pure gold jewelry cannot be less than 99%or 99.9%. The low -melting material of such a diced point alone cannot be welded successfully. Therefore, pure gold jewelry cannot be welded with welded.
