Are you sure what you bought is real silver? This is how I test my silver items.

- Today we will discuss how to identify silver products. Firstly, I will use a strong magnet. Silver products exhibit a certain degree of non-magnetism. The magnet will not attract the silver and will slowly slide off the surface.
Next, I will use silver cleaning solution to try and restore the silver product to its original shiny silver color.
If both of these tests fail, I will resort to destructive testing. I will break the product and dissolve it using nitric acid. Finally, I will observe if it can be restored to silver again.
Thanks for sharing. I was told people can use high-heat flame to remove the stain or tarnish from silver trinkets since the melting temperature of silver amounts to 1000 degree Celsius, is that true?
I have seen people doing this on their TH-cam channel, but I have not tried this myself.
請問一般人買到銀幣是否以下兩種方法驗證就可以?
1.看有磁性否?
2.先查一下該幣的圓徑和厚度是否符合原廠規格,再秤重是否也符合,尺寸和比重若也相同應該就沒問題了吧!
可以,但是這樣會刮傷幣面喔
錫 不會軟嗎?
挺厚的,但確實不硬,可能有混合其他金屬
其實只要測一下密度, 聽一下聲音, 就知道是不是銀啦...
網路很多類似手環的銀飾品產物 它們稱之為 藏銀
藏銀還有三成的銀含量,這個手鐲印上了925的鋼印,卻一點銀都沒有,真的太惡劣了
@@-martinthealchemist113 Frankly, I highly doubt the alloy in so-called ' Tibet silver ' has any silver component, they're noting but a fake.

很難是銀的
藏銀是低含量銀 沒辦法跟s925比 s925 跟 999都稱為純銀 只是s925是以前才會出現的 現在的製品大多都是純銀
藏銀就是白铜,苗银才有3成含银量。
