A photograph of an open outdoor furnace on bare red-brown earth, built from grey concrete blocks around a flat metal plate. Bright orange flames and glowing embers burn beneath the plate, with smoke rising. Scattered around are a grey lump of metal or slag, a dark rock, a pair of tongs or a long iron rod, and piles of ash and debris. A corrugated metal wall sits at the top edge. No people are visible; the scene shows a metal casting or smelting setup.
