Question 2: The bracelet is black. How to clean it? How to maintain silver jewelry _0506 18?
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)

Common surface treatment methods of silver jewelry _0506 18
The easy oxidation of silver is its weakness, and it is also 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 ornaments, but they don't know how to maintain them. They even think that silver ornaments are difficult to maintain, which is 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. Silver ornaments are difficult to rub white after many blackening.
These are some basic considerations. Here is a detailed introduction to the maintenance methods of electroplated and unplated silver ornaments:
First of all, it is necessary to distinguish whether there is electroplating (silver ornaments are generally divided into electroplating and non-electroplating):
There are 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; Identification of electroplating methods ... >>

Besides being used for decoration, some people will use the energy emitted by the crystal to improve their fortune, enhance their fortune and even cure diseases, so it is necessary to take care of the crystal, because if the crystal is polluted, it will destroy its efficacy and its due brilliance. Next, we will introduce you to various crystal cleaning steps and precautions:
Sunshine degaussing cleaning method, moonlight starlight irradiation method, sea salt soaking method, sea salt burial method, snow pile burial method, water purification method, aromatherapy purification method, crystal cluster purification method and natural cleaning method.
(a) the sun degaussing cleaning method:
Cleaning method:
Just put the spar in a place where it can be exposed to direct sunlight, such as windowsill and terrace. The irradiation time is about 30 minutes to 65438 0 hours.
Precautions:
(1) SPAR will focus under sunlight. If paper or other combustible materials are placed near SPAR, there is a danger of fire.
(2) However, the chromogen of spar contains copper and iron, which is not suitable for this cleaning method. Because these substances are exposed to the sun for a long time, they will produce oxidation and make the spar fade. Chromatograms containing copper and iron include red or purple crystals.
(2) moonlight and starlight irradiation method:
Cleaning method:
On the full moon night of the fifteenth lunar month, it is a good time to bask in the stones, because the moonlight is particularly strong that night. The method of drying stones is very simple, just put the spar on the terrace or window and expose it to the sun in the moonlight for one night. In addition, you can also put the spar on the terrace on a clear starry night to let it absorb the essence of starlight, so as to achieve the effect of purifying the spar.
In addition, in addition to the full moon night, you can also choose a few days before and after the full moon, which is also suitable for this method of drying stones.
Precautions:
If the irradiated spar is purple or red, please remember to take it back before noon the next day, otherwise the strong sunlight during the day will affect the pigment of the spar and make it fade.
(3) Sea salt soaking method:
Cleaning method:
Put the spar into a cup of salt water with a proper amount of sea salt (or crude salt) and soak it for three to four hours to dissolve the magnetic field around the spar.
Precautions:
(1) If the spar is made of ornaments embedded in metal objects, such as rings and hanging mouths, please remove the spar from the metal objects before soaking in salt water, otherwise the color and brightness of the metal objects will be affected.
(2) Please note that this cleaning method may change the spar content after cleaning.
(4) Sea salt burial method:
Cleaning method:
As long as the spar is directly buried in the sea salt (or crude salt) pile for several hours, the magnetic field of the spar can be purified.
Precautions:
(1) If the spar is made of ornaments embedded in metal objects, such as rings and hanging mouths, please remove the spar from the metal objects before soaking in salt, otherwise the color and brightness of the metal objects will be affected.
(2) Please note that this cleaning method may change the spar content after cleaning.
(5) Snowdrift burial method:
Cleaning method:
As long as the spar is directly buried in frost and snow for a few hours or so, the magnetic field around the spar can be eliminated.
Precautions:
However, if your spar is relatively large, this cleaning method is not suitable. The main reason is that if the spar is buried in the snow for a period of time and then taken out, it will shrink due to the temperature difference between inside and outside the snow, which may lead to the spar bursting.
(6) Water purification method:
Cleaning method:
You can wash the spar under the faucet for about 20 minutes, which can balance the negative energy of the spar.
Precautions:
But this cleaning method is not suitable for spar such as pyrite or azurite, because these minerals contain iron and copper components and cannot be washed with water.
(7) Aromatherapy purification method:
Cleaning method:
Light some incense or agarwood indoors, and then put the spar in it to smoke, which has the effect of purifying the magnetic field of spar.
Precautions:
Please be careful when lighting incense, and pay attention to whether there are flammable items such as confetti. Put it near the purified spar sea to avoid fire.
(8) purification method of crystal cluster:
Cleaning method:
Please go to the crystal shop to buy a crystal string weighing about 4 kg, and then put the spar on it. You can charge the spar through the energy emitted by the crystal string and remove the impurities of the crystal at the same time, thus eliminating the magnetic field of the spar.
Precautions:

Question 9: A pink crystal was worn by a silver hand. I wonder if it's wet. The passing powder crystals turn black. Is there any way to wash off black? Powder crystal turns black? Wear a silver bracelet I don't quite understand what kind of bracelet it is. It's black. It should be because the gold-plated layer has faded, so it is black. The faded black can't be washed away, and it needs to be gilded again. Is there a gold-plated bag outside the powder crystal? If you remove it, you can directly pass through the hole where the powder is cut, without worrying about fading.
Question 10: How to clean the silver bracelet? If it is pure silver, that is, silver ornaments without platinum plating on the surface are easy to oxidize into black gray. Soak the silver jewelry in white vinegar for 48 hours to remove the faint black oxide layer, then rinse it with clear water and brush the silver jewelry with toothpaste to completely remove the black oxide layer.
2. Silver jewelry that has been worn for a long time, especially silver-plated, should be soaked in the solution of "Imperial Salt" and clear water for 24 hours, and the longest time is 1 month. Imperial salt is a kind of salt with high mineral content produced in Japan, which can eliminate dead skin tissue in a short time and will not cause discoloration of silver jewelry. Sometimes it is also used to purify jade and crystal jewelry.
Primary color, polished surface, the simplest, you can go to the jewelry store and let the master polish it with a cloth wheel. After polishing the cloth wheel, wipe it with silver cloth. If there are cracks on the unpolished surface, just wash it with silver washing water. Don't wash too much water with silver at a time, it is better to rub it repeatedly. Too much will reduce the weight of silver.
The electroplating surface should be wiped with soft cloth, preferably high-grade decorative cloth such as chicken skin cloth, because the electroplating layer is very thin, and the wiping of rough cloth and the damage of chemicals will affect the surface brightness. Once it's not as bright as before. Soak the silver jewelry in white vinegar for 48 hours to remove the faint black oxide layer, then rinse it with clear water and brush the silver jewelry with toothpaste to completely remove the black oxide layer. No matter what kind of jewelry it is, it is best for MM to take it off and store it in a dry place when taking a shower and sleeping. Pure silver is a kind of metal that changes color easily, and of course it should change color.
