The silver rings will not fade, but it will be oxidized and black. The chemical properties of silver are stable and the corrosion resistance is also very strong, which is a disadvantage -it is easy to chemically react with the sulfur ions in the air, which turns black (the surface forms sulfur dioxide). rn鉴别方法：rnrn掂重量rn白银密度较一般常见金属略大，一般地讲：“铝质轻、银质重、铜质不轻又不重. "Therefore, the weight can make a preliminary judgment on whether it is silver. If the jewelry is large and the weight is lighter, it can be preliminarily determined that the jewelry is other metals. In the hardness The silver hardness is lower than that of copper, and it is larger than the lead and tin. It can be tested with the inconspicuous places where the jewelry is scratched. Quality jewelry; if it is a lead and tin texture, the traces are obvious and prominent; if there are traces of the physical objects, but not obvious, it can be preliminarily determined as silver jewelry. The sound rhyme This silver jewelry throwing sound, no elasticity, the sound is "卟 卟 卟". The lower the color, the lower the sound, and the higher the sound, the higher the rhyme; if it is copper, the sound is higher and sharp, and the rhyme sounds are short and short; , No elasticity.
extension information The maintenance method of sterling silver jewelry: 1, the best maintenance method of pure silver jewelry is wearing every day, because human oil can produce natural and warm gloss Essence 2. Do not wear other precious metal jewelry when wearing silver jewelry to avoid collision deformation or abrasion. 3, keep the sterling silver jewelry dry, don't wear swimming, do not approach hot springs and seawater. When not in use, you can use cotton cloth or noodle paper to gently wipe the surface, remove water and dirt, and place it in a sealed bag or box to avoid contact with air. 4. If the signs of yellowing of sterling silver jewelry are found, the easiest way to use toothpaste to add some water to light the surface. Or clean the fine seam of the silver jewelry with a jewelry brush, and then use the silver cloth to gently wipe its surface, and you can immediately decorate the original beauty. 5, the sterling silver jewelry is severely yellowed, and the time to soak with silver water should not be soaked for too long.

Real silver rings will not be discolored and will change color. In one of the important factor is that there is a lot of affinity between silver ions and sulfur ions, which is easy to produce chemical reactions. The result of the reaction is that the silver surface produces silver sulfide. Increased silver, the color of the silver surface gradually turned from white to yellow to ash. This chemical change can occur in the case of extremely small amounts. As long as silver encounters a sulfide or sulfur ion of sulfurization or sulfur ions in the air, this chemical reaction will occur. Human sweat also contains sulfur. When it contacts silver products, silver will change color, especially the hydrogen sulfide produced by sewage and garbage emissions in urban air is even more amazing. Therefore, silver color is not surprising.
The silver rings will not fade. If you wear color for a long time, it is because your body has toxins and silver has the effect of detoxifying. If the silver ring is discolored, you can send it to the place where you buy a ring, you should be free to clean it. After cleaning, it will become brighter again.
It won't be faded. After a long time, the color will be darkened. The easiest way to lose the silver is that the rubbing with cotton cloth will be very bright.
It can be washed with toothpaste, but this method of cleaning is to lose part of the silver. (Loss of about 0.1 grams) Although you may not see the loss of the loss of the loss, but the silver jewelry scrubbing with toothpaste is used The speed of being oxidized next time will be faster than this time! This is because the quartz powder in the toothpaste will leave scars on the silver jewelry, so the area and cycle of the oxidation will be faster than now. The best way is to use professional jewelry care liquid to clean it safer.
Id I suggest that when you go back to buy silver jewelry, do not buy ordinary silver jewelry, buy gold -plated silver jewelry, so It's not easy to turn black!
