General alloy ornaments will fade and rust. Relatively durable rhodium-plated jewelry. Or pure gold or pure platinum jewelry. As for chromium plating, it is best not to wear it, because chromium can cause cancer.
Customers often ask the question: Will the things they buy fade? That's understandable.
So I'm here to tell my dear ones.
alloy
◆ Alloy is defined as:
A substance composed of one metal and another (or several) metals or nonmetals, which has the universality of metals. Generally, it is melted into a uniform liquid and solidified. What we are talking about here is mainly a substance called "lead-tin alloy". Mainly used to produce all kinds of exquisite alloy ornaments and alloy handicrafts, such as rings, necklaces, bracelets, earrings, brooches, tie clips, alloy photo frames, religious emblems, etc.
As long as the alloy ornaments are properly maintained, they will be as bright as new for several years and will not turn black. This kind of jewelry does not need to be maintained with very expensive maintenance water, as long as it is kept away from acid, alkali and humid environment.
① It should not be worn when sweating heavily. Especially in the hot summer, jewelry coating is exposed to sweat for a long time, and it is easy to be eroded when it meets the acid and alkali components in sweat.
② Don't wear it when taking a bath or washing your face. Contact with chemicals, jewelry is easy to damage. The smell of bathing, chlorine gas during swimming and salt in seawater will corrode the necklace, so all the ornaments should be taken off before bathing or swimming.
③ Dry with a dry cloth before storage. When not in use, jewelry should be put into jewelry boxes or sealed containers in time to avoid long-term contact with air alone.
Maintenance of sterling silver jewelry.
s925silver
◆925 silver is alloy silver with other metals added. Generally, all the sterling silver ornaments sold in the market are 925 silver, which is also internationally recognized as sterling silver.
The biggest reason for the oxidation of silverware is oxygen in the air, so blocking the air is the best maintenance method.
For example, put the silver ornaments in a sealed plastic bag and then put them in a pearl box to block the contact between air and silver.
When silver is oxidized, you can use silver washing water or silver cloth to wipe the silver ornaments, but silver washing water is more lethal. Please try to wipe them with silver cloth unless you have to. If it is brightened with silver water, it should be rubbed immediately, and the chemicals on the surface should be cleaned and dried with a hair dryer, otherwise the oxygen in the water will accelerate the oxidation of silverware. In addition, soak in 90% alcohol 12 hours, wipe clean and dry; Or squeeze toothpaste on a dry cloth and wipe it directly, and the effect is also very good.
All in all. As long as it is metal, whether it is alloy or silver ornaments, or even gold, it can't resist the power of oxidation.
There is no way to stop them from oxidizing, and we can only find ways to slow down the speed of oxidation. Take good care of them and be beautiful as long as possible.
Finally, I'll tell you an old method. It's convenient and easy. Just carefully apply transparent nail polish to prevent fading. Super good.
Everyone knows that the jewelry we are talking about should be called simulation jewelry strictly.
One of its characteristics is that it will change color. Of course, depending on the quality, the time of color change will be different.
Generally speaking, silver-plated and gold-plated ones are easier to change color than those plated with white K, and the thicker the coating, the less likely it is to change color (of course, the thicker the coating, the easier it is to die-that is, the joints can move originally, but the coating will stick together if it is too thick. Of course, I'm not a producer, I just know a little technology. ) and it is easier to change color in summer than in winter. Because of the hot weather, the chemical reaction will be accelerated. In addition, if jewelry is worn on the human body, the human body will secrete more sweat. Sweat contains salt.
How can we keep jewelry from changing color for a long time?
Simply put, it is to isolate the ornaments from the air. Because the air contains sulfur, carbon dioxide and other chemical components, these will chemically react with jewelry. Practices include: packaging and displaying in transparent bags, or putting them in glass windows. Of course, the actual sales experience tells us that some products are sold naked to sell faster. You can weigh the pros and cons and show them in an appropriate way.
How to restore discolored ornaments as new?
Some people say that silver washing water is used. Yes, washing with silver can immediately make yellow ornaments shiny. But you will find that the next day or the third day, it will return to its original state. I don't advocate this method. Just wash it with silver, for example, an old man peeled a layer of skin alive. After peeling, it is as bright as new, but it will soon become bad and ugly.
Is there a better way? I wonder if you have heard of baking soda? The "baking powder" used for the fermentation of steamed bread that everyone eats contains baking soda. The chemical formula of baking soda is: NaHCO3 baking soda can be bought in big pharmacies.
The method is to soak the color-changing ornaments in water and take them out. Put some baking soda on it. Then use a small toothbrush or something, but don't brush off the drill on it. Then wash it in water. Dry it and it will be as bright as new. The method is the same as washing clothes by hand.
This method can keep the color unchanged for a longer time after washing. And the cost is low, a big bag of baking soda is only four or five yuan.
If the packaged ornaments turn yellow, there is no need to pick them up and wash them. You can polish it with a soft cloth.
With this method, don't throw it away casually. After washing, accessories can also be used for special sales, which can attract popularity and recover costs.
