Use a knife to scoop out the charcoal until you have a small bowl-like container. A gold ring or small necklace should fit nicely into the bowl you have created from the piece of charcoal.

Scrape the bottom of the charcoal bowl so it sits flat on a safe object that won’t burn. Do this outside or in a very well ventilated place.

Place the gold piece into the charcoal container and put on your safety mask or goggles.

Light a propane torch and begin moving the flame over the gold. Hold the flame over the gold until the gold is red-hot.

Prepare to melt the gold. Sprinkle a little borax onto your gold piece. Increase the amount of heat on the torch until the gold starts to melt. It should look bright orange with a green tint as it nears its melting point. All the fine particles of gold will melt together into a bright ball.
