Why do gold shops often recruit people?
Although gold itself has not been corroded, it has a strong chemical affinity with sulfide, and it is easy to adsorb hydrogen sulfide acid gas in the air, and its surface may be dark, such as orange and brownish red. The production of gold products needs to go through many complicated processes.
Take gold bars and coins for example. They all go through the processes of smelting, tabletting, blank cutting, blank pressing, quenching, acid frying, polishing, pressing and edge pressing. The working environment cannot be a vacuum environment. Every link may encounter dust and impurities in the air attached to the blank of the product. These impurities may become erythema after being stored for a period of time without quenching and pickling.
