The Advanced Furnace is a perk for the Miner Class on MedievalCraft, it is unlocked at level 40 and can then be crafted.
The advanced furnace has 3 slots, which act as a highly efficiant queuing system, there are also 3 product slots. It is a must have for any blacksmith/miner and a very usefull thing to have in a kingdom!
This is the recipe, I was on SSP when I took the screenshot and it does not work correctly. I have tried it on SMP and it works 100%
