Human: Write a detailed description of a gloomy scene inside a building workshop with shovels, crucible, coal, and fire. Assistant: 
Windows high up in the stone walls provide just a hint of fresh air over the stench of burning coal and molten metal. Supported by chains from a wooden beam, a heavy ceramic crucible swings over the fire or over to the molds lined against the wall. Shovels protrude from a pile of fuel nearby, the blackened coal waiting to be added to the fire.
