As a Gold Smelting Machine Supplier, share with you. The elders at home like
to buy gold, thinking that the value of gold is preserved. Even if it is not
worn every day, it can be a heritage for children in the future.
Recently, someone saw a question saying that there is old gold stored in the family for decades. I don’t know whether to keep it or send it to a gold store to replace it with new gold.
If you want to replace it, you feel that the old gold is too old, the style is not trendy, and you won’t wear it normally; you don’t want to change it, and you are worried that the price increase of the old gold will grow very fierce in the future. inestimable.

If you put old gold and new gold together, should everyone be able to tell quickly?
Let's not talk about the texture first. At first glance, the old gold color is not as bright as the new gold. The surface is imprinted with the signs of years, and the new gold has a strong sense of luster. There is no historical staleness except for its own pattern.
Generally speaking, the old gold color is yellower and the texture is softer, the new gold color will be lighter and the texture is harder.
1. It is also a gold product. Why does old gold look yellower than new gold?
Because the old gold has been worn for many years, plus decades of tossing and even hundreds of years of tossing, the surface naturally forms a layer of paste.
Moreover, in the old days, some gold shops used turmeric powder to bake the processed gold jewelry to add a layer of color, thereby increasing the color of the gold jewelry. Therefore, the old gold will look more yellow.
The color of the new gold is lighter because the modern polishing process is more advanced than in the past, so the new gold becomes shiny after being polished. The higher the brightness, the lighter the color.
2. It is also a gold product. Why does old gold feel softer than new gold?
In the past, after the processing of old gold was completed, there would be an additional process called "tempering".
Tempering is a kind of metal treatment process, which can reduce the hardness of the metal and enhance the toughness and ductility. Tempering gold jewelry can make jewelry soft.
Nowadays, when processing gold, the tempering process is cancelled. On the one hand, it is to maintain the hardness of the gold jewelry to facilitate wearing, and on the other hand, to prevent the gloss of the jewelry surface from weakening.
Is old gold worthless or worthless?
In fact, purely from the perspective of purity, the purity of old gold is not as high as that of current gold. The purity of regular gold jewelry sold on the market today can reach a maximum of 99.99%. However, in the past, this technology was not available, and the purity is not so high.
The true value of old gold is not reflected in the purity of gold, but its craft value and historical value.
