The social and economic development is so fast now, and various commodities are full of people can not meet the needs.
No matter who it is, whatever, how much heart and eye it takes.
Especially when buying valuable products, when you know enough about a product, you can take the initiative in your own hands.
So how can the silver cup judge true or false? After all, there are too many silver plated products on the market!
1. Thermal conductivity method: due to the strong thermal conductivity of silver, we can pour a little boiling water into the bottom of the silver cup, and then touch the silver part of the cup mouth with our hands. If we feel hot immediately, we can be sure that the purity of silver in the cup is at least 80%, and it will not be a silver plated product.
2. Bleach test method: the bleach is highly oxidizing. Drop a drop of bleach on the inner liner of the silver cup. The surface of silver liner was observed carefully. If the silver liner darkens or darkens immediately, the purity of the silver is higher.
3. Magnet identification method: only need a magnet placed on the inner wall of the silver cup, feel that the magnetic is false, no magnetic is true! Because real pure silver does not form a magnetic field. On the contrary, most fake cups are made of stainless steel + electroplating, so they are magnetic!
4. Listen to the sound: take a one yuan coin and put it into the cup. Listen to the sound: if the sound is low, buzzing and not loud, it can be judged that it is pure silver; on the contrary, if the sound is clear and green, the loud one is silver plated cup.
