    Iron melts at 1800°C (3270°F) and gold melts at 1062°C (1943°F). Because iron has a higher melting temperature than gold, we hope that, even with our limited resources, we can get a furnace originally used to smelt iron to work our gold. A furnace also helps maintain certain chemical conditions during smelting.
