A person in protective gear is stirring molten material in a furnace. The furnace is circular and lined with firebrick, glowing with intense heat. The person, wearing a silver protective apron and gloves, uses a long metal rod with a tool on the end to agitate the molten substance. Sparks fly from the furnace opening. The furnace sits on a gray, bolted metal base, and a red fire extinguisher is visible in the background. A metal plate rests on the side of the furnace top.
