The Silverware Turns Black Doesn't Mean Your Body In Detoxification

Silverware has always been one of the favorite jewelry(GNN  necklace) but many people encounter silver blackening in the process of wearing silver. What is the reason for this? How to deal with silver blackening?

Since the birth of human civilization, gold and silver angel wing necklace is almost a symbol of wealth and status. Because of the high value of gold, the popularity of silverware is relatively high.

Although silverware does not seem to have characteristics in terms of color, the reflectivity of silver to visible light is still quite high compared to other metals which more than 90%, so "bling bling" is not an exaggeration.

In the ancient court TV series, there will be a bridge section of “Silver Needle Test Poison” in all likelihood. So, can poison really be tested? Can you use silverware to prove that your body is "detoxifying"?

It's fake that silver can test for poison. In the Song Dynasty, there was a highly skilled forensic doctor called Song Ci. He clearly recorded the case of "silver needle autopsy" in "Collection Of Grievance Relief Stories".

Therefore, the saying that " silver can test for poison " is also circulating in the private sector. However, we must know that the poison that the ancients said mainly refers to arsenic.

Ancient anti-drug technology is still relatively backward, so the arsenic contains some sulfur or sulfides. These substances can react with silver to form a black "silver sulfide" on the surface, which is very conspicuous.

But in modern times, the technology for producing arsenic can be said to be very mature, and there will be no more sulfur mixed, so it will not react with silver anymore. It can be seen that the term "silver can detect poison" is completely wrong now!

Silverware turns black, is it bad? Get Name Necklace will guide you with some facts about it. Many "experts" have made a false claim that the silverware worn has turned black, indicating that the body is not good and detoxification.

Many people still believe that, this is the same as "blood-recognition", which is nonsense. Silver ornaments also slowly turn black in the air, although silver is chemically stable, it is slowly oxidized by oxygen to form a black silver oxide.

If the content of sulfide in the air is high in the environment, the silver cheap personalized jewelry will become blacker at a faster rate due to the stronger affinity of silver and sulfur. Silver can test poison, but it only reacts with ancient arsenic. Do you think that this substance can be discharged from your body?

Some friends may think that the skin secretions of the human body also contain a little bit of sulfide, which will make the silverware black! Yes, but this is normal and has nothing to do with “detoxification”.

Why is the silverware worn more and more black? Silver is chemically stable and has a high resistance to corrosion. As a disadvantage, it is easy to chemically react with sulfur ions in the air, which turns black (the surface forms sulfur oxides).

Silverware has turned black, how to clean and maintain? In the past, this problem was not really good to solved. There are a few kinds of common metals that are more resistant to corrosion than silver.

It is even rarer to have high reflectivity like silver. So in order to overcome this shortcoming of silver, the most common treatment method is to make the silver alloy. Therefore, the most common silver ornaments on the market are 92.5% silver (ie 925 silver), which is relatively not easy to blacken.

After being processed into an alloy, the hardness of the silverware is also effectively improved. There is a way to clean the silver, which allows us to enjoy the beauty of silver, just need an aluminium container and a little saltwater.

Since the binding strength of silver sulfide to the substrate is relatively strong, the most appropriate method is to reduce the silver sulfide, and the degree of loss of silver couples jewellery is also reduced, and aluminium is an excellent reducing agent.

Nowadays, aluminium pans are not very common, but the cans are all over the place. Open and peeled off the inner coating, then tightly attached to the silverware. In a concentrated brine, a wonderful electrochemical reaction can be made. "Black Silver" has turned white again.

Therefore, knowing a little science can not only know the beauty of these silver ornaments but also benefit from the selection of more ideal silver ornaments.

There is another simpler way to clean the slightly darkened silverware, which is to use toothpaste. In the choice of toothpaste, it is recommended that you buy a transparent, jelly-like gel toothpaste. Do not use a toothpaste containing particles, which may damage the surface of the silverware.
