ingot mold or any type of casting mold Gather separate and clean the gold scrap you want to melt. Remember to be careful that the same karat gold is sorted together.
You can mix scrap of different karat, however the result may be gold of lesser karat and may not work as well for your jewelry making project or change the gold scrap prices you want to obtain.
As a rule of thumb and to remain in compliance with FTC labeling laws for gold jewelry, it is a good idea to sort the gold by karat (eg. 14K with 14k).
Once you have cleaned and sorted your gold scrap, cut it into small pieces. This helps the melting process.
Cover the crucible with borax or flux to help the metal move and melt faster. Place the gold into the crucible
Melt the gold with your torch until it is a hot liquid. Gold tends to require a temperature of approximately 1650 degrees. Wait until the gold has melted into liquid and pour the gold into the ingot mold.
Once the mold has cooled down, you can use the rolling mill to make gold sheet or wire.
Continue to run the gold through the rolling mill until you achieve the gauge you need. You may need to anneal the metal every time you run it through the mill to soften it.
Remember to take all the necessary safety precautions when melting metal. I always keep a bucket filled with cold water in case a need to cool the metal faster.
This process requires some practice and in time you will be able to produce the gold medal and wire that you need to create your own unique jewelry designs. This technique can help you maintain more consistent gold scrap prices.
