Old gold is a popular source of materials to make new jewelry, including rings. Melt down any scrap gold, old outdated or broken jewelry and turn the scrap into gold sheet or wire that can be used to fashion a ring. Melting down old gold offers a way to recycle and is likely to be less expensive than buying fabricated gold for your gold jewelry projects.
Collect old gold. Check to be sure all the old gold is the same karat.
Cut your old gold into pieces.
Put the small cut pieces of old gold into a crucible painted with borax to act as flux.
Melt the old gold with a torch or two until the gold is liquid.
Pour the liquid gold into a mold designed to make gold sheet metal or wire.
Allow the gold to cool to room temperature. Roll the molded gold through a rolling mill until the sheet or wire is the gauge you need to make your ring; 18-gauge gold sheet or 14-gauge wire are good sizes to create a ring.
Wrap the 18-gauge gold sheet or 14-gauge wire around a ring mandrel to form the gold into the shape of a ring. Use a forming hammer to round out your ring.
Check the ring mandrel to be sure the ring is sized correctly. Cut off excess gold wire or sheet using a jewelry saw.
Solder the gold ring closed.
Finish the gold ring by sanding away tool marks using 220-grit wet/dry sandpaper. Switch to 400-grit, 600-grit and 800-grit sandpaper until the ring is polished.
