Can You Turn 14k Gold Into 24k

How To Melt Gold Step by Step

For example, 14k gold is roughly 58 percent gold content, 18k gold is roughly 75 percent gold content and 24k gold is pure gold. It is possible to use a chemical process to remove these excess materials so that your gold is more refined. Using this process, you can turn lower quality gold into pure 24k gold.

    Things you should know about Melting Gold

    Gold melts at a much cooler temperature about 2,000 degrees Fahrenheit but that’s enough to survive most house fires. Platinum jewelry is the priciest, so it’s a good thing that the metal’s melting point is just higher than 3,200 degrees Fahrenheit. Sapphire and Ruby also possess extremely high melting points.

    How Do You Melt Gold Jewelry

    Can I do this at home?

    Answer by dhp

    You definitely can NOT do this at home, it is both dangerous and likely impossible. Gold is a metal, which means you will need to achieve very high temperatures and have the right equipment both to melt it and manage it after melting. Leave this to the professionals.

    Answer by SallyJ64

    Melting gold takes extreme heat and you would need a foundry to do so. The only way to do this is to get it done professionally by someone who has the equipment.

    Answer by lala13

    No. Do not do this at home. You need to go to a jeweler or a place/person that buys gold. Gold melts at higher temperatures and it would not be safe to do this at home. YOu need to go to a professional to request that this be done, as they have proper equipment and tools.

    Answer by

    i think you cant do this in your home.. only goldsmith knew the melting range of gold.. it is taken in a sand container heated and melted use some salt elements..

    Answer by Cecilia

    You can melt gold jewelry at home but it’s probably not a good idea. You don’t want to mix karats and you want to remove any stones. Then you need some pretty specialized equipment. Take it to several local jewelers and ask for an estimate. The range will surprise you.

    Answer by Darkephoenix

    No, you can not melt gold at home without special equipment. It requires extremely high temperatures to melt and is NOT safe to attempt without the proper tools.

    Melt Gold Using The Propane

    The most efficient way to melt gold at home is by using a propane torch. This method will melt gold in a matter of minutes.

  • Place the gold inside a graphite crucible. Then, gradually direct the propane torch toward the gold. As the torch transfers heat, the gold will begin to spread out, protecting the underlying layers of gold from flowing out of the crucible.
  • Adding borax to the gold can slow down the melting speed. This is ideal if you have a sizeable amount of gold to melt. However, attempting to melt too much metal fast can break the crucible or cause the gold to explode under the intense heat.
  • When melting fine gold particles or powder, be sure to direct the torch throughout the crucible so that the entire quantity of gold melts evenly.
  • Once it has melted, use a pair of industrial tongs to transfer the liquefied gold into a mold of your desired shape.
  • Pro Tip: Consider using an oxy-acetylene torch if you need more heat. This is ideal if you are looking to melt a large amount of gold within the shortest time possible.

    Smelting Gold Everything You Need To Know

    How To Make Gold Melt

    There are a variety of methods that you can use for smelting gold, but the main equipment necessary is a heat source and a crucible, a heatproof container for the gold. Make sure that you research thoroughly and are completely prepared when you begin the process because without certain precautions smelting can be dangerous. Its important to pay attention to the material of your container to ensure that smelting will not cause it to crack. Additionally, having long, heat sensitive tongs is beneficial for transporting the gold.

    It is important to wear heat-proof goggles and gloves when smelting gold in case of materials escaping from their container. Another precaution that frequent gold smelters often practice is having a separate area in which to perform the process, such as a workbench or shed a few feet from the house. This ensures that your work will be further away if an emergency happens, which is always a good thing. Also, you would never want your children to happen across a heat source such as a propane torch, so having a separate work area is strongly advised.

    Traditional Gold Bar Production Technology

    The first step in the process of making gold bars is that the ore must be extracted from the ground. After a gold-bearing deposit has been located, the gold is extracted by mining. In old times hydraulic mining was often performed using high pressure water jets to mine, move and separate gold from deposits. However in modern times, explosives are used. Much of the ore from which gold is mined in modern times is not the nugget-laden ore one imagines from the old days of the gold rush, but is low grade ore. A ton of low-grade gold ore may only yield on average 6.5 grams of gold however the high value of the gold still makes the operation worthwhile.

    After the rock containing the gold has been mined, it is crushed to grains the size of sand. Next, gold is extracted from the crushed rock using a multi-stage process. The preliminary processing varies slightly depending on the quality and composition of the ore, but eventually the gold is dissolved from the ore using cyanide, in a process called leaching: A water and cyanide solution is added to the gold, which is then ground to a mud. The mud is agitated and air is bubbled through it, which causes the gold to react with the cyanide and dissolve. Zinc powder is added to the dissolved gold solution and the resulting solids collected.

    Obtain Other Heat Sources

    If you are unable to buy a microwave or electric furnace, you may have to be more creative when obtaining a heat source for smelting gold. A propane torch can be a successful heat source, and an added bonus is that it will melt the gold within a few minutes. To use a torch, place the gold into a crucible, place the crucible on a surface that withstands heat, and point your propane torch toward the gold. Add chemical borax to the gold first if you need it to melt at lower temperatures.

    If the gold in the crucible is fine and powdered, it is important to move the torch down to it very gradually to avoid blowing it around and to make sure the crucible is heated slowly to ensure that it doesnt crack. An oxy-acetylene torch melts the gold faster than propane, which is important to keep in mind when buying your equipment. Hold your torch above your gold and move it slowly in a circle. When the gold powder becomes red it has begun to heat up and you can begin to work the torch in gradually until the powder forms into a nugget-like shape.

  • 1Try 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. However, a torch will melt gold within a few minutes.
  • The gold should be placed into a crucible. Then, put the crucible on a fireproof surface, and direct a torch toward the gold within the crucible. If you add the chemical borax to the gold first, you can melt it at lower temperatures, which might be needed if youre using a torch.
  • Be careful to bring the torch down slowly if you have fine powdered gold in the crucible because you could easily blow it around. Heating the crucible too fast also could crack it. You want to heat it thoroughly and slowly. An oxy-acetylene torch will melt the gold faster than propane.XResearch source
  • With a torch, hold the flame well above the gold powder and slowly work in a circular motion. Once the powder begins to heat up and turn red, you can begin to work the torch in slowly until your powder is reduced to a nugget.
  • 2Shape your melted gold. You need to decide what you are going to do with the melted gold. Perhaps you want to sell it in a new form. You could try to make an ingot out of it or another shape, like a gold bar.
  • Pour the melted gold into the ingot mold or other mold before it hardens. Then, let the gold cool. The mold should be made from similar material as the crucible
  • Dont forget to clean up your mess! You never want to leave heat sources unattended or in the reach of children.
