Odd furnace. Is it supposed to be made of cast metal or something? If so, it would be a tremeandous waste of energy. Or is the shape indicative of some hidden meaning? If anything, I would have the narrow part at the top and the wider bit at the bottom.
Also that's the earliest picture of double action bellows that I have seen so far, I suspect they are a late 16th/ early 17th century invention at the moment, never seen any real research about them.
