Scratch test Gold is a very soft element, so scratching it will leave marks. Use a knife to try and scratch the surface of your rock. If it's gold, you'll see scratches. Pyrite will be too hard to be affected, and mica will flake off when scratched. If you don't have a knife handy, scratch gold with a piece of copper (like a penny).

With some borax, heat, and a little know-how, it's possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.
