Instructions
Place the gold dental crowns that you would like to melt into a crucible. A crucible is a container made from metal or thick ceramic that is used to melt gold by placing it under very high temperatures. After filling the crucible with the gold, place it on a fireproof surface such as brick or cement
Put on safety goggles and leather gloves. Light the propane torch with a lighter, and turn the gas to the highest setting. Place the flame to the gold, moving it in a slightly circular pattern so the heat reaches the edges of the metal. As the gold begins to liquefy, add 1/2 tsp. of borax to prevent oxidation of the metal. Continue to heat the gold until it has completely melted, then turn off the torch.
Pour the melted gold from the crucible into a button-style mold using the metal tongs. The gold will re-harden in the mold as it cools, and can be used to create something at a later date.
