The Electric Furnace is a medium-sized, rectangular industrial machine with a clean, metallic exterior. It features a large, glowing heating element at its center, visible through a reinforced glass panel, emitting a soft orange light when active. The furnace has a pixel-art isometric design with sharp edges and a functional, no-nonsense appearance, typical of Factorio's industrial aesthetic. Its base is sturdy and slightly raised, with visible electrical conduits and vents for heat dissipation. The color scheme is predominantly steel gray with accent colors indicating input and output ports.
