Human: Make a concise location description of a dark scene inside a building with a crucible, a bellows, and stone molds. Assistant: 
The floor slopes toward a circular firepit fed by a large pile of crushed coal. A huge iron crucible hangs over the fire, suspended by heavy chains from a thick wooden beam. A leather bellows lies close at hand, while stone molds of various sizes and shapes, waiting to be filled, line the far wall. The only exit is a blackened doorway to the west.
