If You Have Sentimental Reasons To Re
If you have strong feelings about your grandfathers wedding band or the ring that came over from the old country 100 years ago, its understandable that you may want that actual gold to used in your design no matter what.
There is a way to do this. I work with a refiner who will refine the troublesome alloys out of a small amount of gold. I can then directly use your gold, add more fresh gold and do a single casting that will use your gold. It is not an economical way to go, but it is doable.
How Does Any Gold Item Melt
Jewelers say this is a laborious process that takes anywhere from two weeks to a month. Before the melting procedure, you need to clean the gold from dust, dirt that could get there, impurities can spoil appearance future product. At the beginning, the gold that you brought to remelt is placed in a special container, where it is heated to the melting point, namely, to 1064 degrees Celsius.
When all the items placed in the thicket have completely melted until a homogeneous mass is obtained, the master places it in a special mold. This form will depend on what you want the output to be. After that, the object that you want to get is made from the dissolved gold, like a ring, earrings, bracelet or chain.
How Do I Calculate Gold Coin Melt Value
Here are the steps for calculating gold coin value:
Measure the weight of the gold.
Note the purity of the gold in percentage.
Find the current price per unit mass of gold.
Multiply the weight with the quality and the current price, which mathematically is:
Value of gold = Weight of gold × × Price per unit mass of gold

Scientists Find Way To Melt Gold At Room Temperature
Melting gold normally requires temperatures upwards of 1,064° C , but physics is never quite that simple. A team of researchers has now found a way to melt gold at room temperature using an electric field and an electron microscope.
Although we’re all familiar with the phenomenon of melting, most of us don’t really think about the physics behind the process. Essentially, when something melts all that’s happening is that the bonds between its molecules break down and they begin to move more freely. For instance, they might transition from the well-ordered structure of an ice cube to the less ordered state of a shapeless puddle of water.
Heat is the usual trigger for the change, but it’s not the only one pressure plays a part too. Experimenting with those conditions has let scientists do all sorts of unexpected things recently, like making water freeze at temperatures well above its usual boiling point.
In the new study, the researchers tested another trigger: an electric field. The team placed a small piece of gold in an electron microscope, and observed it at the highest level of magnification. Then, they slowly ramped up the strength of an electric field to see how the gold atoms reacted.
“I was really stunned by the discovery,” says Ludvig de Knoop, first author of the study. “This is an extraordinary phenomenon, and it gives us new, foundational knowledge of gold.”
The research was published in the journal Physical Review Materials.
Refining Scrap Gold Faq
What Is A Scrap Gold Refining Lot
All the metal delivered to us as a refining lot are first inspected for magnetic metals like iron, low grade stainless steel, nickel, and cobalt. Once the magnetics are removed and other non-precious metals are removed, all of the gold, the 10k, 14k, 18k for example are combined and melted together into one homogeneous mass and poured into an ingot mold forning a bar.
When molten, a small pin sample was drawn and saved for future analysis to determine the final purity of the poured ingot. The pin sample is then analyzed by x-ray fluorescence spectromerty and/or fire assay to determine purity. That is, how much pure gold, 24k gold, is contained in the ingot. This amount of pure gold can now be sold on the market or placed in your pool account and sold later. There is no need to wait for the final refining process phase
The impure bar, or ingot, then proceeds to the primary refinery where the pure metals are separated and reclaimed. All of the gold, copper, silver. Most of the other trace elemnts have no value and are discarded. This final refining phase can take up to 18 months to complete.
Diamonds reclaimed from stone removal lots can also be “frosted” to determine whether or not they are in fact diamonds. Frosting service subjects the stones to an acid bath which will mar the finish, or “frost” the stones that are not diamond. Diamond frosting will help separate zircon and glass from diamond.

Recycling: Its Hip And Old Golds Not Helping You By Taking Up Space
A better alternative to trying to re-cast your old jewelry is to recycle it. I give my clients credit on old gold jewelry that they use toward new projects.
For example, my client Mary was helped in paying for her new ruby and diamond ring by giving me a heavy old broken chain worth $500.00. And my contractor client Billy, totally paid for the repair of his wedding band by trading in his old, out of date, 70s gold bracelet. I actually gave him money when I delivered his wedding band to him. It was cool and made us laugh.
What if that tangled ball of ancient gold chains in the back of your jewelry box would actually pay for a brand new ring? Wouldnt that be nice!
Before You Start Melting Gold
It is important to remember that before melting the gold you should remove the impurities in the metal by using flux. This chemical will remove all of the impurities in your gold. The fewer the impurities, the easier it is to meltdown or refine your gold because there wont be much else besides metal. Depending on the size of the gold melting project, there are numerous forms of flux solutions.
To refine gold and keep small gold particles together for DIY gold melting projects, you may use accessible chemicals like borax and sodium bicarbonate. Borax is available to purchase in the home cleaning section of your local grocery store. Sodium carbonate is produced when you heat baking soda , which is also known as sodium bicarbonate.
To create a decent DIY flux, combine borax and sodium carbonate in an equal amount. Add 3 to 4 pinches of flux for each ounce of gold melted. If the gold is particularly dirty, you may add a pinch or two more of flux. However, keep in mind that applying too much flux might cause it to eat through ceramic crucibles.

Each person was once presented with gold items that either did not fit in size or did not like in shape. Not many partners can please a capricious lady with a gift. To melt gold and make another piece of jewelry out of it, which will delight you is a rather difficult and long process. Many jewelry workshops accept jewelry for melting that did not suit you, did not like it, and was torn. Sometimes a completely new ring can be made from a torn bracelet or chain, which will delight you no longer on the neck or hand, but will look elegant on the phalanx of the finger.

Hassles With Melting Your Old Gold Jewellery
Remove Impurities Using Flux
Before melting your gold, you must get rid of the impurities in the metal using flux.
- No matter how clean your gold items seem, they contain some traces of impurities that should be eliminated before starting the melting process. A chemical known as flux is used to remove impurities from gold the fewer the impurities, the easier it will be to melt the metal.
- Flux also coalesces fine gold particles, preventing them from being blown away during the melting process. Never melt fine gold particles using a propane torch without applying fluxthis will result in massive losses as the force from the torch will blow the gold particles into the air, leaving you with little or nothing to smelt.
- There are different types of flux formulas depending on the extent of the gold melting project. For DIY gold melting projects, you can use accessible compounds such as borax and sodium bicarbonate to refine the gold and hold fine gold particles together.
- Purchase borax from the home cleaning aisle in your local grocery store. Heating bicarbonate or baking soda will produce sodium carbonate.
- Mix borax and sodium carbonate in equal portions to form an effective DIY flux. For each ounce of gold you want to melt, add 3 to 4 pinches of flux. You can increase the amount of flux by a pinch or two if the gold is particularly dirty. However, be careful not to apply excessive flux flux containing borax eats through ceramic crucibles, creating a hole and rendering the crucible useless.

Remelting With A Homemade Furnace
If it is not possible to buy a muffle furnace for melting gold, you can make a furnace for melting metals. The first thing is to define the requirements for such a furnace. It should be compact and easy to use, while still having a wide heating range. With enough skills, you can assemble such a stove at home on your own.
It will look like this: carbon-graphite powder is poured between two electrodes, which are made of graphite and to which a voltage of 25-50 V is transmitted. For the stove, you will need a very powerful transformer . Gradual and intense heating is formed in graphite powder due to its characteristics, making gold melting as efficient as possible. The main advantage of such a furnace is the fact that it can heat the required sample to very high temperatures, including those required to melt gold.
The furnace heats up in 3-5 minutes, which allows you to fairly accurately control the metal soldering process. The oven itself is made from available materials: ceramic or cement tiles, mica and graphite. The dimensions of the furnace, that is, the distance between the electrodes, directly depends on the output voltage of the transformer. The volume of the furnace will be enough to melt a few grams of metal.
