In fact, the concept of silverware can be poisoned is only effective in ancient times, because the poison used by the ancients was arsenic dioxide, that is, cream, which was restricted by history, science and technology. The reaction sulfur and sulfide, so the surface of the silver needle will generate a layer of black "silver sulfide".

The refinement technology of today's society is very mature, and can be perfectly extracted from sulfur and sulfide. Therefore, not only the average frost will not react with the silver needle, but even except for almost every episode of "Detective Conan". In addition to chemicals, toxic substances such as nitrite, pesticides, and poisonous drugs will not turn black after contacting silver needles.
