Before going through the arduous task of building a furnace of your own, you need to know the definitions of some technical terms you might encounter when researching how to melt gold. The five most common ones you’ll find on the internet are smithing, forging, karats, oxidation, and ductility. Smithing and forging are synonyms that both mean using...
The furnace is the heart of every forge. Without it, you won’t a high-enough source of heat to melt your gold and shape it into something useful. Thankfully, you won’t need thousands of dollars of equipment to make a furnace that will burn hot enough for you to begin smithing. First, determine how much gold you intend to melt. The size of the furna...
Most gold items you’ll find in the market are zinc, copper, and nickel alloysbecause these minerals allow gold to keep its shape. Thankfully, none of them bond with oxygen at the same temperature as your precious metal. Using a mixture of sulfuric acid, sodium nitrate, and silica, you can watch the zinc, lead, copper, and nickel parts surface at th...
Place your gold ore into the crucible and start heating the furnace by setting alight the charcoal surrounding it. As the charcoal turns orange, put your crucible directly on top and add some more until it’s full up to the sides. Turn your hairdryer on so your coals burn with more steady heat. You’re going to need a lot of air and charcoal to reach...
Before your gold begins to cool, take it out of the furnace and pour it into your casting dish. A casting dish with no bends or creases will give you a flat plate or coin shape, perfect for inscription if you want to make it truly yours. If you’d like to turn your gold into another more complex shape, you’ll need to look into gold casting, which is...

- Getting the Right Equipment. Buy a crucible container to hold the gold as it melts. You need the right equipment to melt gold. A crucible is a container that is specifically designed to hold gold as it melts because it can withstand the extreme heat.
- Using a Heating Kit. Buy an electric furnace that is used for melting gold. These are small, high-powered kilns that are specifically designed to melt precious metals, including gold and silver.
- Finding Other Sources of Heat. Try using a propane torch to melt gold. As noted before, you must be extremely careful about safety concerns if you are going to use a torch.
- Melt Gold with a Metal Melting Furnace. If you want to melt a lot of gold for DIY projects, a metal melting furnace may be a smart investment. Melting gold in furnaces with Borax is easy!
- Melt Gold with a Propane Torch. If you don’t want to use an electric furnace or microwave, then you can melt gold with a propane torch. All you need are scrap or some jewelry pieces, sodium bicarbonate, and water.
- Melt Gold with Microwave. If you want to melt gold flake or dust, then you can use a microwave. Here are the steps: Place small portions of gold flakes inside a crucible.
