Gold Smelting: Everything You Need to Know

Do you have any gold jewelry that you don’t wear? Maybe it’s been sitting in your jewelry box for a long time and collecting dust. If that’s the case, smelting the gold might be a good choice. Smelting is when you melt down the gold and get rid of all the other materials that are mixed in with it.

Gold smelting has been practiced for centuries as a time-honored method for purifying and forming metals. People discovered this process a long time ago, and it helped start the Bronze Age. People started using this process to create new weapons for war.

If you have gold at home that you want to turn into something else, smelting is a process you can do yourself with the right equipment and precautions.

What Is Smelting?

Although many people think smelting and melting are the same, they are not. Smelting is when you turn a solid into a liquid using heat. When it is melted, the material becomes a liquid. But when it cools down, it becomes solid again.

Smelting is a process that changes the chemical content of a material. When you smelt, you remove other materials mixed with the gold. This leaves pure gold. In addition to copper, silver, and lead, additional metals that can be melted include copper, silver, and lead. Historically, smelting was employed to produce guns for World War I. Currently, it is also utilized to manufacture smartphones.

This is a good hobby for people who like science and have a lot of extra metal at home. It is affordable and easy to do if you have the right equipment. Smelting gold cleans it of any sand, dirt, or other metals, making it more beautiful and valuable.

Why Smelt Gold?

Gold smelting is a viable choice if you wish to create gold jewelry or artwork. This is the process of melting gold together with other substances. Gold is an elegant technique to enhance the appearance of your artwork, and it is exquisite for earrings and necklaces. Gold smelting is also beneficial if you have unused jewelry or gold objects.

If you melt down your old gold, you will earn extra money. Gold smelting is superior to gold melting because melting gold successfully is more difficult.

Smelting Gold – Everything You Need to Know

There are different ways to smelt gold. The main equipment you need is a heat source and a crucible- a heat-proof container for the gold. Make sure you research thoroughly before starting because smelting can be dangerous if you’re not careful.

You need to pay attention to your container’s material to ensure it will not crack when you smelt the gold. It is also helpful to have long tongs that can withstand high temperatures to move the gold safely.

When smelting gold, it is important to wear heat-proof goggles and gloves in case materials escape from their container. A separate location, such as a workbench or shed a few feet from home, is also recommended.

This will help keep you safe if something bad happens. It’s also a good idea to have a separate workplace for your children, in case they see something hazardous by accident.

Use Flux To Remove Impurities

This technique for gold smelting employs a flux. Borax and sodium carbonate constitutes the flow. The first step is to purchase a crucible vessel. This container can endure the melting process’s high temperatures.

Typically composed of clay or graphite carbon, a crucible can tolerate extremely high temperatures without shattering.

If you cannot get a crucible, you can use a potato to hold the gold during the melting process. Cut a hole in the potato and pour gold into it. Ensure you have a pair of heat-resistant tongs for handling the crucible or potato.

You can add flux to your gold once you have the necessary gold-smelting equipment. The more impure the gold, the greater the quantity of flux required to purify it.

There are many ways to create flux, but combining borax and sodium carbonate is the most common way. This can be done by buying regular baking soda and heating it. For every ounce of gold, you will need two pinches of flux. However, if the jewelry scraps are dirty, you need to use more flux.

The flux holds the gold particles together while removing impurities from the gold. Make sure you take safety precautions when you perform this method!

Use a Healing Kit

You can use an electric furnace if you don’t have access to a crucible or flux. Electric furnaces are available online to melt precious metals like gold and silver. They let you mix metals and melt them at home, which is perfect for gold smelting.

Suppose you plan on smelting the gold item containing silver, copper, or zinc. In that case, the heat level necessary for smelting will be lower. It will require less heat to melt the gold and be easier.

Another option for smelting gold is a 1,200-watt microwave. The magnetron should be located on the side or back of the microwave, not on the top. You can also buy a microwave gold smelting kit or a kiln which you can place on a kiln shelf in the microwave.

If you use a microwave for smelting gold, do not cook food in it again. This can be dangerous.

Obtain Other Heat Sources

If you don’t have a microwave or electric furnace, you can use a propane torch to heat the gold. It only takes a few minutes to melt it.

To use a torch, but the gold in a crucible. Put the crucible on something that doesn’t melt when it gets hot. And then use the torch to heat the gold. If you need to melt it at a lower temperature, add chemical borax first.

If the gold is in a fine and powdered form, it is important to slowly move the torch down to it to avoid blowing it around. Make sure to heat the crucible slowly so that it doesn’t crack. When using an oxy-acetylene torch, remember that it melts gold faster than propane. Hold your torch above your gold and slowly rotate it in a circular motion.

When the gold powder turns red, it begins to heat. You can gently mold it into a nugget-like form with the flame.

Shaping Your Gold

After successfully purifying and melting your gold, you must determine what to do with it. This decision depends on the intended use of the melted gold. Will it be sold, fashioned into earrings, or used for other purposes?

If using a mold, pour the gold into the mold before it sets. Allow it to cool completely. When deciding on a mold, ensure the material is similar to the crucible.

Many people shape their gold into blocks. These blocks are called ingots. They are easy to weigh and transport because they are square-shaped.

If you are making jewelry out of gold, you may need smaller molds in the shapes of your jewelry pieces. You can do this by packing sand inside a crucible. The sand can be carved, hollowed, or shaped to your desired form. However, the mold must be ready for your smelted gold immediately because it cools and hardens quickly.


These methods can help anyone become an amateur alchemist. Melting gold is a great way to use old jewelry or start a new craft. If you’re looking to sell your melted gold, you can use your new abilities to earn some cash.

Ensure that safety procedures are taken when melting gold. This involves wearing protective eyewear and gloves and removing combustible objects from the area. Now that you understand the objective and steps of this procedure, go to smelting!

Frequently Asked Questions About Gold Smelting

Does Smelting Gold Purify It?

Gold smelting is a process used to purify gold. The process removes impurities from gold ore. These could be the original impurities found in gold deposits on the earth or impurities added to gold in manufacturing.

Can I Smelt Gold at Home?

The best way to melt gold at home is by using a propane torch. This method will melt the gold in minutes. Place the gold inside a graphite crucible. Then, direct the propane torch gradually toward the gold.

Can You Sell Melted Gold?

People who buy gold jewelry usually melt it down to get the metal without paying for the craftsmanship or style. This means that traders must pay a smelter up to 30% of the gold’s value to purify it. Then, the dealer makes a profit when they sell it.

What Does Borax Do When Melting Gold?

Borax helps dissolve impurities like oxides when you are melting gold or silver. The fluid borate slag will collect on the surface of the metal. Periodically remove this slag with a carbon-graphite or clay rod.

Is It Hard to Melt Gold?

Gold has a melting point of 1,943 degrees Fahrenheit (1064 °C). If you want to melt it down, you will need hot temperatures. Make sure you use the right container. You will also need a pair of tongs to move the crucible and hold it.

Who First Smelted Gold?

Gold smelting began around 6000-3000 BC. The technique started in Mesopotamia or Syria. In ancient Greece, Heraclitus wrote about it.
