How Hot Does Coal Burn? | Reference

Outside of a crucible or forge, coal can burn at a temperature as high as 3590 degrees F, since there's more air and the coal won't lose energy warming up the forge. This temperature makes it possible to melt even tungsten, which has the highest melting temperature of any metal on the periodic table.
