Silver jewelry is very common in the market, and naturally there will be many sayings about the efficacy of silver. So what are the following statements and which are true and false?
Use silver needle to try out whether the food is toxic
Poison in the ancient, mainly refers to the highly toxic arsenic, namely arsenic trioxide. The ancient production technology is backward, causing the arsenic to be accompanied by a small amount of sulfur and sulfide. The sulfur contained in it is in contact with silver and can react chemically. The surface of the silver needle is made of a black " sulfur -silver", and the egg yolk also contains sulfur, which can also make the silver needle black.
Wearing silver turns black which means that the body is not good.
When shopping at a gold and silver family necklace jewelry store, there are often clerk telling guests that buying silver jewelry is good for the human body. If the silverware worn turns black, it proves that your constitution is weak, and the silverware can help you absorb the body toxin. The more you wear the silverware, the better your body is. In fact, this is an unfounded statement. As already mentioned above, the chemical action of silver and sulfur causes the silver to turn black.

Is 925 silver sterling silver?
Friends who have bought silver jewelry have heard of 925 silver. This silverware has also been labeled as "sterling silver" by many people. Is this pure silver?

Silverware blackened with toothpaste
I often hear people say that if your silver jewelry turns black, you can use toothpaste to clean it, so that the washed silverware is new and bright! This is a popular silverware maintenance method in the private sector. In fact, it is also very effective, just pay attention to the cleaning method. It is best to choose a transparent jelly-like toothpaste for cleaning silver-plated toothpaste. The granular toothpaste will damage the softer silver surface. Do not add water, use a dry hand to rub the silver jewelry, and then wipe the toothpaste attached to the silver my necklace jewelry with a paper towel.
