Gold plating and gold plating are two different processing technologies.
society
This method is more common. Like the literal meaning, gold plating refers to plating a thin layer of gold on the surface of an object. Gold plating is divided into two categories, one is homogeneous material gold plating, and the other is heterogeneous material gold plating. Gold plating of homogeneous materials is gold plating on gold, in order to improve luster. On the other hand, gold plating on the surface of non-gold materials makes raw materials get gold luster, such as silver gold plating and copper gold plating.
We often hear that many jewels have gold-plated signs, so how much gold is there in gold plating? In fact, there is not much gold for gold plating, and the quality of gold plating is also excellent. At present, the international standard is that the coating thickness of gold-plated jewelry is 10 micron to 25 micron. A lot of gold plating on the market is 2-3 microns thick, even a few tenths of a micron, which is not gold plating but gold plating.
Cover with gold leaves
It is to wrap a layer of gold on the material, which is thicker than the gold-plated layer and has much better durability. Gold-plated jewelry will fade when worn for a long time, but this rarely happens when it is covered with gold. Generally speaking, gold-plated jewelry is more expensive than gold-plated jewelry, precisely because the gold-plated process uses more gold.
The difference between gold-plated jewelry and gold-plated jewelry
That is, under the same technical and appearance conditions, the former will be much more expensive than the latter.
Generally speaking, gold plating and gold plating are obviously incomparable with pure gold. Both processes hope to keep the beauty of gold, but at the same time, they can greatly reduce the cost, so they use other relatively cheap metals such as copper and silver to make jewelry blanks, and then try to make them look like gold.
