   The furnace, built on the outside of the workshop, featured earthen pipe-like air vents with hundreds of tiny holes in them and a prototype chimney to ensure air goes into the furnace to feed the fire and smoke comes out safely. [39] Passive ventilation and passive cooling systems were widely written about around the Mediterranean by Classical ...
