Will the gold plating oxidize, and will the copper gold plating fade?

Definitely, as jewelry, wear and tear is inevitable after a long time, and your zinc alloy gold-plated jewelry only has a broken gold on the surface to expose the zinc alloy inside. As long as it comes into contact with water, sweat, and these electrolytes, galvanic cell reactions will be formed to accelerate the oxidation of zinc. In other words, your jewelry either doesn't oxidize, or it oxidizes quickly.

No, if the surface is fully gold-plated, it will not oxidize, because gold is an inert metal.

But if you accidentally scratch the plating and expose it, the zinc will oxidize.

If you pay attention to yourself, you'll be fine.

No, at least not in your lifetime. Gold is very stable, and there is doghead gold in nature. degrees of gold will only wear out.

If it is plated with gold (AU), it will not, if it is just brass, it can be distinguished by a strong stroke with a fingernail (there are traces of gold).

However, if the quality of the plating is average, it will come off.

It depends on how long it takes. It is not a problem to not rust and oxidize for more than 10 years, it depends on the environment, and it should be put in a dry place.

Small black spots may appear (depending on how much zinc is used).

If it's pure gold plating, as long as it's not hard grinding, it's okay to pull.

Copper gold plating will fade.

Because the color of copper plating is not its own color, when it comes into contact with some items that cause discoloration, or collides with hard objects, it will cause the surface coating to wear out, and then the metal inside will be oxidized by air, which will also make it gray and dull. Therefore, when maintaining copper gold plating, it is necessary to keep away from acid, alkali, and humid places.

Maintenance method:

Because it is gold-plated, it is plated on the outer surface layer, so try not to cause friction to avoid rubbing off the surface. It is best not to wear it when washing your face and bathing or when you are drenched, and avoid direct contact with acidic and alkaline substances such as soapy water. So it's best not to wear it when you're going to do sports.

Also, try not to touch cosmetics, because the chemicals contained in cosmetics can make your gold-plated jewelry tarnish, fade, etc. The hardness of alloy gold plating will be relatively small, so be careful not to pull it hard, and it is best not to wear it when carrying heavy objects to avoid scratching, etc.

Because the color of copper plating is not its own color, when it comes into contact with some items that cause discoloration, or collides with hard objects, it will cause the surface coating to wear out, and then the metal inside will be oxidized by air, which will also make it gray and dull. Therefore, when maintaining copper gold plating, it is necessary to keep away from acid, alkali, and humid places.

Gold plating will fade, but it will take more severe wear and tear to fade.

Gold plating is a surface treatment technique that electroplates metal on the surface of an object, which can increase the aesthetics and durability of the item. However, the quality and thickness of the gold plating layer are different, which will also affect the durability of the gold plating. Normally, regular gold plating can maintain aesthetics and durability for a longer period of time.

However, if the gold plating layer is of poor quality or not properly handled, it will lead to the problem of gold plating fading or fading. In addition, if used improperly or rubbed for a long time, it may also cause the gold plating to tarnish or fade. Therefore, when using gold-plated products, it is necessary to pay attention to maintenance and use, and avoid excessive friction and collision to maintain their beauty and durability.

Precautions for wearing gold-plated jewelry

1. Avoid contact with chemicals: Chemicals are easy to corrode metal surfaces, so avoid contact with chemicals when wearing gold-plated jewelry, such as perfume, shower gel, etc.

2. Avoid contact with water: water is easy to fade or oxidize the metal surface, and you should avoid contact with water when wearing gold-plated jewelry, such as swimming, bathing, etc.

3. Avoid collision: gold-plated jewelry is fragile and easy to be damaged by collision, so you should avoid colliding with hard objects when wearing.

4. Regular cleaning: gold-plated jewelry is easy to be contaminated with dust and dirt, and should be cleaned regularly after wearing it for a period of time to avoid affecting the appearance and service life.

5. Storage precautions: gold-plated jewelry should be stored in a dry, ventilated, cool and dark place, avoiding direct sunlight or humid environment, so as not to cause oxidation or discoloration.

Silver gold plating will fade.

In fact, silver gilding is very easy to understand, that is, to add a layer of gold coating on the basis of silver jewelry, this process will generally choose the electroplating method, using transparent red or orange-red paint to coat the surface of silver accessories. Silver gold plating is actually adding a layer of gold paint to the surface of silver jewelry, so that silver jewelry has a more shiny color and is more fashionable and beautiful.

When we choose accessories, many sterling silver accessories will also show metallic colors, at this time the shopping guide will tell us that this is the use of silver gilding technology. Silver gold plating will fade, because silver gold plating is only plated on the surface of silver jewelry with a very thin layer of **, after a long time of wear, it will always receive wear, when the ** plated on the surface is worn, it will reveal the silver. Slag racket.

Pay attention to maintenance

And the real ** jewelry will not fade, and long-term wear will only be subject to wear and tear. If you want to wear silver-plated gold-plated jewelry without fading, you need to pay attention to maintenance in daily life, such as trying not to wear silver-plated gold when doing housework, because it is easy to wear off the yellow gold plating.

It is also not recommended to wear it in the bath, as silver gold plating is prone to chemical reactions after contact with shampoo, shower gel and other items containing chemicals, accelerating the loss of silver gold plating. The normal ** will not fade, only wear and tear, but the luster is not as good as before, but after proper maintenance and repair, the sock beam liquid can be renewed.

Copper gold-plated jewelry that is not properly cared for will fade.

This type of jewelry does not need to be maintained with very expensive maintenance water, as long as it is protected from acid, alkali and humid environments. Humid environments include: bathing, washing the face without it, sweating profusely without wearing, and drying with a dry cloth before storage.

1 desiccant should be placed in the jewelry box where the jewelry is placed; When not worn, it should be put into the jewelry box in time. If not properly cared for, brass-plated jewellery will fade.

Do not wear jewelry when exercising, any accessories including silver jewelry, minerals, etc. should not be worn during exercise, because a lot of sweat will be produced during exercise, and sweat is the biggest natural enemy of jewelry.

Do not wear jewelry when touching chemical agents, such as shower gel and shampoo when taking a shower, facial cleanser when washing your face, and liquid foundation and makeup when applying makeup. Long-term contact with the chemicals contained in them will produce a certain chemical reaction.

Jewelry maintenance method:

1. Store jewelry separately and do not mix it with other jewelry or hard objects to avoid grinding the surface.

2. Avoid long-term contact with sweat, which will corrode the surface.

3. Please remove the product when bathing and washing to avoid direct contact with acid and alkali substances.

4. Use water, toothpaste, and soft brush to clean to restore the surface brightness (grinding and scratching will not be able to recover).

5. When collecting, please use cotton cloth or tissue paper to remove sweat and dirt on the surface before storing it in a sealed bag.

6. It is easy to rub the flowers in the collision, be careful in storage, do not overlap the jewelry, and should be stored in the original packaging bag or placed in the jewelry box with an independent small grid to avoid rubbing the surface of each other.
