Within a rudimentary workshop in Adankolo, Nigeria, a shirtless, lean adult male is observed operating a large brick furnace. The man, wearing dark shorts, flip-flops, and dark gloves, holds a long metallic rod with both hands, inserting it into the rectangular opening of the furnace. The furnace, constructed from brick and partially covered in light-colored plaster, shows significant soot staining around its opening, which reveals a visible accumulation of glowing embers and ash. A metal door is partially open to the immediate right of the furnace opening. The ground in the immediate foreground consists of compacted earth mixed with ash, gravel, and fragmented bricks. An unpainted corrugated metal roof, supported by visible wooden beams, covers the structure, allowing sunlight to penetrate from above.
