Are the big gold chains on the market pure gold? How is it made?

Are the big gold chains on the market pure gold? How is it made? The owner of the gold shop finally told the truth!

Nowadays, with the popularity of costume dramas, many people have a different love for gold jewelry, ** itself is rare, so his ** is more expensive, so it is classified as *** ranks, although the popularity of various gemstone strings now looks very foreign, but ** jewelry can always bring people a symbol of status, many people show off their wealth depends on **, some people are several gold beads as soon as they make a shot, and even the neck is hung with a thick gold chain, which makes people look very envious, Although many people will think that they are showing off with a gold chain, but you must know that showing off also requires capital, and a chain composed of gold beads around the neck is at least a hundred thousand, just imagine what kind of symbol a person will be if he puts hundreds of thousands around his neck?

For a while, gold chains were in vogue, as if people all over the street had such a chain around their necks, but was this chain pure gold or not? We all know that the texture of ** is softer than silver, and only 1g of ** can make dozens of meters of thin strips, if you want to make ** into a thick chain, it is technically impossible to achieve, so we can deduce that the gold chain is not pure gold texture, it is bound to be mixed with some synthetic metal materials to create a large gold chain.

It is understood that the materials required to make gold chains are sand gold and alloy, and the gold chains made in this way are a little worse than ** in terms of fineness and conduct, so the last process is also needed, gold plating. The large gold chain that is only done is plated with **, so that its appearance is no different from **, although the gold chain is not pure gold, but its gold content is still standard to some extent. The color of the finished gold chain is the same as that of the **, although the big gold chain looks good on the neck, but in order for it to be not easily damaged, it is necessary to mix some other metals to ensure its forming.

To make gold chains, you need to put sand gold and alloy in a crucible, heat and melt to form a relatively strong gold, and then use a relatively strong alloy to process it into metal wire with a hot rolling process.

After the gold is made, the color is relatively dull, so you need to soak it in the water of the king, a piece of jewelry has been initially formed, and finally the jewelry made is gilded, which looks the same as the jewelry made of pure gold. To sum up, large gold chains are not pure gold, and the thicker the chain, the lower the purity; Wearing a gold chain is a kind of temperament, even if it is not pure gold, as long as the temperament is there, it is very attractive.

It is pure gold, which is formed by melting gold in a special container and pouring it into a mold, which is a relatively simple process.

It's not pure gold, I think it's just a layer of gold paint on it.

None of these gold chains are pure gold. Most of them are plated with a layer of copper on the iron chain to get by.

The large gold chain is made by fusing sand gold and alloy at high temperatures.

Loved by people. **The texture is soft and the extension is very good, whether it is ancient or modern, people's popularity of it is very high and does not necessarily decrease in the slightest. It can also be a symbol of high status.

In TV, people who have been noble for seventy or eighty years, or who have a certain social status, will wear a large gold chain around their necks, and the gold chain makes people want to ignore it, which is enviable.

The big gold chain is not made of pure **. Everyone knows that **of** is not low, how can such a large gold chain be made of pure gold, which is mixed with synthetic metal materials. The large gold chain is actually made of sand gold and alloy melted in a crucible with a temperature of up to 1000 degrees Celsius to form an alloy liquid.

After the alloy liquid is poured into the die-casting machine, it can be quickly cooled down, and then die-cast through a round steel mold, and the large gold rod comes out. Put the big gold rod into the two large rollers of the extended rolling mill, roll it from right to left, repeat many times, and the big gold rod "**" becomes a small gold rod, and the small gold rod is accurately processed by the finishing mill and transformed into a gold bar with noodle thickness. At this time, the gold bars can be made into coarse gold chains, while the fine gold chains have to be processed by a finishing mill.

Gold bars have to go through a twisting ring before they can become gold chains.

Gold chains mixed with other alloy materials can be compared to gold in color, and the key link is gold plating. Students who have listened to chemistry class know that gold plating is done by electrolytic cells, connecting the metal to be plated with the cathode, the gold with the anode, and the electrolyte is an electrolyte containing gold elements.

In this way, the large gold chain can have the color of gold.

The production process of the big gold chain is to put the sand gold and alloy in the smelting furnace to heat and melt, and then process it into metal wire, and then process it into a large gold chain according to human needs.

First of all, a certain proportion of the metal raw material is placed in a crucible for high-temperature melting. Then, the melted liquid is poured into a die-casting machine to cool down, and then die-cast through a round steel mold, rolled on the upper and lower rollers to form a thin and long metal body like noodles, and then put it in the oven for annealing to make it soft. Finally, use a torsion ring machine to make it form, and then weld the left and right sides.

It is made by a more mature master and in accordance with the drawings of the design drawings, so the big gold chain will be extraordinarily exquisite.

Made from molds. The gold is melted at a high temperature and placed in a mold, where it is cooled and molded into a chain.

Of course, it's made with **.
