The best way to melt gold is in a melting dish, a shallow bowl shaped dish made from clay, silica, or some similar material that the gold will not blend with. In a pinch, you can use a piece of charcoal with a hollow area carved into it. If you're desperate to melt it, you can use a piece of drywall or a block of wood.
