There is no problem using silver bowls and spoons to eat, but tableware made of silver will be heavier, so it will be more tiring for babies to use. As long as it is made of real silver, there is no problem. If you buy inferior or fake silver, it will cause harm to the body. When purchasing, you can tell whether it is pure silver by listening to the sound and color. (1) Advantages: Using a silver spoon can kill bacteria, as silver ions can inactivate and kill most bacteria in the water. The mechanism is that silver ions are highly active and can adsorb bacteria in the water and gradually penetrate into the bacteria, causing the bacteria to lose their metabolic ability and die. (2) Disadvantages: The silver spoon is a bit heavy to pick up, which is quite a burden for children. How to identify the authenticity of a silver spoon? 1. Sound judgment Financial calendar, news express, precious metals simulated trading, precious metals expert live broadcast room, Jijinhao crude oil and precious metals market software Silver is soft and makes a weak sound when it is thrown onto a hard object, while other metals make a crisp sound. 2. Color judgment The white color of other metals is different from silvery white after all, and the difference is particularly obvious after cooling after burning. After being roasted with fire, if it is real silver, the silver color will not change; if it is fake silver or a low-quality product, it will turn black after being roasted. Another method is to drip nitric acid on the surface of the silver spoon. After wiping off the nitric acid, the surface of the silver spoon is still silvery white, which indicates that the silver content is quite high. If the silver spoon has a low silver content, it will be gray-black. |
