Can long-term use of silver tableware lead to heavy metal poisoning? Is this inconsistent with the use of silver tableware for health preservation?
Pure silver silverware has a natural bactericidal effect and will not be poisoned by heavy metals. However, if the alloy is plated with silver, if the alloy material precipitates, it will easily cause health hazards. There is no contradiction between using silver tableware and keeping in good health.

Silver can form a small amount of silver ions in water, adsorb bacteria, make the enzymes on which it breathes lose their function, and make bacteria die quickly. Using silver powder as disinfectant of water is 10 times more effective than adding chlorine for sterilization. When people make water purifiers and mineral spring pots, they often use silver-containing materials in their filters and disinfectants. Therefore, silver tableware can not only decorate the dining table, but also be everyone's health guardian.

But it should be noted that silver tableware also has the characteristics of fast heat conduction, hot mouth, soft texture and easy oxidation. It is inconvenient and unaccustomed to use, so it should be maintained frequently. And many silver tableware is not pure silver, but alloy silver plating. If the alloy material precipitates, it is easy to cause health hazards.
