Remelting of gold, is it necessary and in what cases?

Most likely, everyone had cases in their lives,when the favorite gold ornaments broke down, thin chains burst, one piece from the pair, an earring, was lost, for example. Or just the decoration became irrelevant, out of fashion ... One of the acceptable solutions from this situation is, for example, remelting the rings from gold into a new piece of jewelry.

Before deciding to re-melting

The melting of gold by itself is an eventunprofitable. And the more unprofitable it will be, the smaller the weight of the remelted product. The fact is that when there is a remelting of gold, there is a process of technological abrasion. The volume index of abnormalities directly depends on the sample of the product (the lower the sample, the higher the index) and can reach 10%. Therefore, if a final decision is made to re-melt the product, it is better to collect more gold scrap as much as possible, and then to give it to the jewelery workshop.

Remelting products from gold: an individual method

There are two ways of melting gold, and they both do not contain any super complicated technological nuances:

1. Initially, products and scrap are cleaned of dust and dirt.
2. Then, with an individual method of melting scrap is placed in a special cup or even a spoon for melting. To warm up the metal, a gas burner is usually used.
3. The molten metal can be pre-alloyed into an ingot for further work with it, or it can be immediately poured into the prepared form.

Remelting of gold: a centralized method

Another method of melting gold is called centralized. In this case, not one or two pieces of jewelry are melted, but some quantity of gold scrap from different products with different breakdown.

Here, the finished alloy will have a test different fromsource materials. The sample is determined using a special chemical analysis after cooling of the metal. Such remelting of gold is not made with the help of a heating pad - special electric furnaces with electrodes are used. Also, during the melting process for a cleaner metal, graphite powder is used at the outlet. There are also high-frequency furnaces for melting gold, but they are advisable to use them already on an industrial scale.

The duration of the process and its cost

There are many factors that affect both theduration, and the cost of the process of melting gold scrap and making a finished jewelry. This is the complexity of the product ordered by the customer, and what kind of samples are scrap gold for remelting. Of course, not the last place is the skill of the jeweler, who will work with the product.

On average, the production time can vary fromseveral hours - to melt a simple gold ingot - and up to several months, when it comes to a complex weaving jewelry and with inserts of precious stones.

Samples of gold: what are, what is meant

And finally, for those who do not know, I would like towould say a few words about what a test is. In itself gold - metal is very soft and unstable before the influence of physical factors. Therefore, for everyday wearing it is not suitable, and to give it a fortress, as well as a special stable shade, gold is fused with other metals, such as silver, copper, etc.

So, that very test is the amount of pureGold in the product in comparison with the amount of impurities of other metals. We can see six samples: 375, 500, 583, 585, 750, 958. Take, for example, the 375th test. This number means that in a thousand grams of the alloy of pure gold was only 375 grams, and the remaining 625 accounted for impurities. Well, accordingly, the 958th test - for one kilogram of pure gold alloy will account for 958 grams, and for impurities - only 42 grams. So the amount of impurities is considered for the remaining samples.
