Pour the acid-and-bleach mixture into the plastic bowl with the ore grains and stir. Allow four hours for the gold to dissolve, stirring every 20 minutes. The chlorine reacts with the gold inside the ore to form gold chloride. Filter the ore and bleach solution to remove all the impurities, such as soil and rock fragments.

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.

Quartz is a mineral composed of silicon and oxygen, with a chemical composition of SiO 2. It is the most abundant mineral in Earth's crust and is resistant to both chemical and physical weathering. When rocks weather away, the residual material usually contains quartz. This is why the sand at most of the world's beaches is quartz.

It's worth noting here that dissolved gold is basically real gold in liquid form. During this process, the liquid reacts to its environment and eventually materializes in the fissures and cracks of various minerals, like quartz for example. Similar to gold, quartz is a 'mineral fluid' which travels upward and solidifies into its mined form.
