Silver ornaments should not be stored in damp places for a long time. If you find symptoms of oxidation, such as black surface, wipe the surface of the silver necklace with a soft cloth and toothpaste dipped in water until the light is scattered again.
A silver necklace will get brighter and brighter when worn by healthy people, and will turn black when worn by unhealthy people? Is that so? It doesn't matter. In addition to the advantages of beautiful color and reasonable price, it should be noted that silver jewelry will turn black if worn for a long time. This is because silver reacts with sulfur in the air to produce black silver sulfide, which affects the appearance. If it has been oxidized and blackened, it can be dipped in silver washing water or wiped with a silver cloth. You can also scrub with a soft brush dipped in toothpaste and dry it with cotton cloth after washing.
The most practical method is to use a toothpaste brush, but be sure to dry it.
Is wearing a silver necklace healthy? Silver jewelry has no effect on health. Exposure to air for a long time will naturally be oxidized to black, rather than poor health making silver black.
What should I do if the silver necklace turns black? Silver does not change color. Maybe you are not suitable for silver.
Silver is an unstable element, which easily reacts with sulfur, leading to blackening. Human sweat contains a lot of sulfur, which will work when it comes into contact with silver ornaments. Moreover, if people are in some polluted environments and there are many compounds such as acid gas, hydrogen sulfide and nitric oxide in the air, the silver ornaments will turn black. Even under normal circumstances, the surface of silver jewelry will be oxidized and the color will become dull after being worn for about half a year.
Silver bracelets turn red, probably because silver ornaments contain antimony or arsenic. These two elements will turn brick red when they react with sulfur, indicating that the composition of silver jewelry is seriously impure. Mainly do the following work:
① Don't wear other precious metal jewelry when wearing silver jewelry to avoid collision, deformation or wear.
(2) Avoid contact with water vapor and chemicals, and avoid swimming in clothes, especially in the sea.
③ Wipe it with cotton cloth after wearing it every day, and put it in a jewelry box or bag for sealed preservation.
④ It has been oxidized and blackened, so you can use a soft brush dipped in toothpaste; You can also wash it with soap or detergent by hand; If it is not clean, it can only be scrubbed with silver washing water; Dry it with cotton cloth after washing.
The easiest way is to gently clean the surface with toothpaste and some water. Or use a small jewelry brush to clean up the fine seams of the silver ornaments, and then gently wipe the surface with a silver cloth, and the original aesthetic feeling of the ornaments can be restored immediately. (If the silver cloth can restore about 80% to 90% of silver, don't use silver lotion and silver washing water, because they are corrosive to some extent, and silver ornaments are more likely to turn yellow after using these products. In addition, the silver wiping cloth contains silver maintenance ingredients and cannot be washed with water.
Many friends like sterling silver ornaments, but they don't know how to maintain them. In fact, we only need to spend some time in our daily life to make silver ornaments last as long as new. 1, the best way to maintain silver jewelry is to wear it every day, because human oil can produce a natural and moist luster. 2. Don't wear other precious metal jewelry when wearing silver jewelry to avoid collision, deformation or wear. Keep the silver ornaments dry, don't wear them to swim, and don't go near hot springs and seawater. When not in use, you can gently wipe the surface with cotton cloth or paper towel to remove moisture and dirt, and put it in a sealed bag or box to avoid contact with air. If the silver ornaments show signs of yellowing, the easiest way is to gently wash the surface with toothpaste and some water. Or use a small jewelry brush to clean up the fine seams of the silver ornaments, and then gently wipe the surface with a silver cloth, and the original aesthetic feeling of the ornaments can be restored immediately. (If the silver cloth can restore about 80% to 90% of silver, don't use silver lotion and silver washing water, because they are corrosive to some extent, and silver ornaments are more likely to turn yellow after using these products. In addition, silver cloth contains silver maintenance ingredients and cannot be washed with water. ) 5. The silverware is seriously yellow, so it should not be soaked in silver washing water for too long, usually a few seconds. Wash it with clean water immediately after taking it out, and then blot it with paper towels. Common surface treatment methods of silver jewelry _0506 18 Silver is easy to oxidize, which is a defect in its yoga and a headache for consumers and producers. At present, the common silver surface treatment methods in the domestic market are further oxidation, electroplating and untreated. Whether it is further oxidized or untreated, the characteristics of silver oxidation blackening are fully utilized. Using oxidants to deepen the oxidation of the silver surface, or using the natural oxidation of the silver surface to produce richer colors and mechanism effects in silver jewelry, so that the defects are not concealed, is a method of exerting strength. The real way to prevent the surface oxidation of silver jewelry is electroplating. At present, the commonly used methods are silver plating, rhodium plating, palladium plating and so on. The silver jewelry produced by European goldsmiths mainly adopts deep oxidation treatment and sandblasting electroplating treatment. Common knowledge of silver jewelry maintenance _0506 18 Many people like silver jewelry, but they don't know how to maintain it. They even think that silver jewelry is difficult to maintain. That was not the case. The chemical properties of silver are not as stable as platinum and gold, and it is often oxidized to black or yellow by water or other chemicals in the air, losing its luster. After understanding this feature, we only need to spend a little thought in our daily life to make the silver ornaments we wear last as long as new. When wearing silver jewelry, don't wear other precious metal jewelry at the same time to avoid collision, deformation or wear. Keep the silver ornaments dry, don't swim in them, and don't go near hot springs and seawater. After each wear, you can gently wipe the surface with cotton cloth or paper towel to remove moisture and dirt, and then put it in a sealed bag to avoid contact with air. The best way to maintain silver jewelry is to wear it every day, because human oil can produce a natural and moist luster. Contains exquisite three-dimensional silver ornaments made into sculptures to avoid deliberate polishing. If you find that the silver ornaments are yellow, you should first clean up the thin seams of the silver ornaments with a small jewelry brush, and then gently wipe the surface with a silver cloth to restore the original silvery white and brightness. I suggest that if the silver cloth can recover about 80% silver, there is no need to use silver lotion and silver washing water, because these products are corrosive to some extent, and silver ornaments are more likely to turn yellow after using these products. Silver wipes contain silver maintenance ingredients and cannot be washed. If you don't handle and collect the silver jewelry after wearing it, it is very likely that the silver jewelry will turn black. At this time, you should use a small jewelry brush to clean the fine seams of jewelry, then drop a drop of silver emulsion on the paper towel to wipe off the black oxide on the surface of jewelry, and then use a silver cloth to restore the original brightness of jewelry. After that, you should remember to do the daily general maintenance to prevent the silver ornaments from turning black again. It is difficult to rub the silver ornaments white after many times of blackening. These are some basic considerations. Here is a detailed introduction to the maintenance methods of electroplated and unplated silver ornaments: firstly, it is necessary to distinguish whether there is electroplating (silver ornaments are generally divided into electroplated and unplated): electroplated silver ornaments, that is, the inner layer is pure silver and the surface is being treated with current; Electroplating is generally divided into electrogold and platinum; The way to identify electroplating is that its surface is brighter than pure silver, just like a mirror, which has good reflective effect and is not easy to oxidize (the oxidation time depends on the thickness of electroplating). Electroless silver ornaments are easy to lose their luster due to vulcanization (sulfur dioxide in the air reacts with silver to form a layer of silver sulfide on the silver ornaments, just like apples will slowly turn black after being cut). The simple treatment method of electroplating silver jewelry is as follows: 1. First, go to a nearby Chinese medicine shop or drugstore to buy a pack of alum; 2. Boil the silver jewelry you are wearing with 10:: alum 1 water (water must be boiled); 3. Take out the silver ornaments and put them in cold water. Use a soft brush (such as a toothbrush) dipped in toothpaste or laundry detergent or salad for cleaning. 4, blow dry with a hair dryer, and then wipe it with suede until it is as bright as new. The types of electroplated silver ornaments that can be treated above are: A. Necklace (thickness can be used) B. Pendant C. Ring (with or without gems) D. Bracelet, bracelet (thickness can be used) E. Silver ornaments inlaid with plastic and the like.
What should I wash the silver necklace when it turns black? The specific methods mainly include:
1, brush with toothpaste and toothbrush.
2. Apply lipstick on the cloth, then wipe the silver ornaments, and finally rinse them with water.
3. It is absolutely effective to apply the correction fluid to the silver jewelry and wipe the silver jewelry with a cloth before the correction fluid dries.
The method of chemical whitening is relatively simple, and its principle is to destroy the oxide film on the surface of silver jewelry through chemical reduction reaction. Compared with physical methods, chemical methods are relatively simple, and will not leave scratches on silver ornaments, which is more suitable for our daily life.
Specifically, there are the following methods:
1. Soak in Coca-Cola containing carbonic acid 12 hours.
2. Wash and cook with vinegar, which contains acetic acid.
3. Soak overnight tea, which contains oxalic acid.
4. Wipe with a silver cloth, which has chemical components to remove silver oxide.
5. Soak in silver washing water for one or two minutes, and then rinse with plenty of water.
