The piece I was using here is a bit less than half of the chunk I acquired. Would be good if it was at least useful for something.
Get a nice big pile of coals and bury it as close to the middle as possible then let it cool down on its own.
Since you're already going to have the bonfire might as well try it. Nothing ventured, nothing gained.
Cut a test piece after the annealing to see if its machinable. If so find someone with a big tub (Blanchard) grinder to finish the top & bottom at a reasonable price.. A reasonable price should be much less than buying a new piece of material.
