古时候,我国蒙古族牧民们就发现,马奶放在普通碗里,几天之后就会发臭变坏,然而,盛放在银碗里的马奶却能较长时间不变质。人们还发现,用银碗盛水或在盛水的碗里放一把银匙,就是经过几个月,水也不会变质。古埃及人在两千多年前就知道把银片覆盖在伤口上,可防止感染,伤口好得也快 In ancient times, our Mongolian herdsmen discovered that horse milk was placed in a common bowl and that it would stink and deteriorate after a few days. However, horse milk held in a silver bowl could not be degraded for a long time. People also discovered that after a silver bowl is filled with water or a silver spoon is placed in a water-filled bowl, the water does not deteriorate in a matter of months. The ancient Egyptians knew more than 2,000 years ago that they covered silver on wounds, prevented infection, and wounded quickly.
