Matters needing attention when wearing gold and silver jewelry

What are the precautions for wearing silver jewelry?

Tools / raw materials silver jewelry cosmetics

Salt water washing powder nitric acid after egg poultry deterioration

Method / step

1. Cosmetics contain not only mercury but also sulfur, which causes silver to form black silver sulfide. In addition, if the air contains sulfur, it is also not suitable to wear silver. Those who live in chemical plants or work in chemical plants should pay attention, and even more can not wear silver!

2. Ozone can also cause silver to turn black. For example, negative ion generators and disinfection cabinets used in daily life should not be placed with silver jewelry.

3, some eggs and poultry will produce hydrogen sulfide gas after the deterioration, if the staff working with the egg and poultry is not suitable for wearing during working hours.

4. The purification of tap water often contains bleaching powder or chlorine gas, which has a serious erosive effect on silver. The eroded silver loses its luster and produces white silver chloride. Therefore, it is not advisable to wear silver to bathe.

5. The washing powder contains bleaching agent. The main component of the bleaching agent is chlorine, which has a certain corrosive effect on silver.

6. Mercury (mercury) and silver will work, serious damage will occur, and even a mercury paste will be formed. Therefore, be careful when using body temperature.

7. Silver is dissolved in hydrochloric acid and nitric acid. If you are engaged in this work, you should pay attention.

Matters needing attention In summary, silver easily absorbs mercury. After absorbing mercury, the surface quality is seriously damaged and completely loses its luster, forming a silver amalgam (also known as mercury silver). In humid air, silver is easily corroded by sulfur vapor and hydrogen sulfide, making the surface black. This is one of the basic conditions for the formation of Thai silver, so we have to wear silver jewelry in our daily life. Keep an eye out.
