Infernal Furnace (Thaumcraft 6)

The Infernal Furnace is a 3x3 construct added by Thaumcraft 6. It acts as a standard furnace, except it does not require any fuel and expels items through the Iron Bars, so a Hopper or Hungry Chest will be useful for storing smelted items. Unless it is supported with arcane bellow, the process is incredibly slow. When meat is being cooked it has a chance to also give a nugget corresponding to the type of meat.This is also the way for obtaining Rare Earths.
