Nowadays, precious metal silver is not only an ornament on the hands and necks of beautiful women, but also more and more silver daily necessities, such as silver bowls and silver combs, which are very popular. Take a 990 silver spoon weighing 17.5 15g as an example. After adding 5 yuan/gram, the price is 16 yuan/gram, and the total price of this silver spoon is 280.24 yuan. In the past two years, with the change of people's consumption concept, such handicrafts have become more life-oriented, and more and more people consume and use silverware products. In ancient times, the silverware used by the emperor has also "flown" into the homes of ordinary people. In addition, when many consumers refer to silver tableware, it is generally understood that "using a silver spoon is good for your health", and many salespeople use it as a selling point. It is believed that long-term use of silver tableware can release silver ions, which has strong adsorption and will play a role in sterilization and detoxification.
