This is a blueprint for theoretically infinite recursive smelting in the Factorissimo mod. The theory is, most of the input is passed to the next level while a small amount is done on each level. This blueprint is far from perfect, but can handle up to 16 blue belts of Iron/copper input/output with 32 nested levels.
