Harm of drinking water with 990 silver cup for a long time: Silver is an inert metal, which will not chemically react with common liquids such as boiled water, so it can be used as a drinking cup. However, if the glass contains more inert metal salts than it, it is likely to dissolve silver and cause heavy metal poisoning after entering the human body.

Drinking water from a silver cup has more advantages:

1. In ancient times, when entertaining distinguished guests, large families usually used silver tea sets to show respect for their guests. There is another important purpose. When using silver tableware, silver will react with many toxins, which will make the silverware black and can be used to test whether the food is safe.

Toxic substances will produce a layer of black silver sulfide on the surface of silverware, which will lose its original luster and be easily detected by silverware. In addition to this function, the ancients also said that silver would bring health and wealth to the human body.

2. Silver ion not only has the function of destroying bacterial protein, but also has a super bactericidal function, which is relatively harmless to heavy metal silver. A small amount of silver in the cup will dissolve in water to form silver ions, but a small amount of silver ions can kill many bacteria in the solution. So the silver cup is definitely a good thing to drink.

3. Silver ions are used to prevent infection, so drinking water from a pure silver cup can keep the cup sterile and less bacteria. Usually, drinking water from a silver cup is very beneficial to health, but we need to pay more attention to avoid metal poisoning caused by disharmony between the cup and other substances.

4. Drinking the water in the silver cup has good health care function and is beneficial to human health. Especially if you make tea in a pure silver cup, silver will dissolve in boiling water to produce silver ions, which not only has the functions of antivirus, sterilization and beauty, but also can improve human immunity.
