Transform boring furnaces into efficient smelting machines, capable of holding more material, and yielding more product in less time. In the more furnaces mod, players can create better furnaces by crafting their old ones, allowing one furnace to hold more material. This saves space in homes while smelting more material efficiently.
Diamond furnaces increase the efficiency of fuel used, and obsidian furnaces allow for two materials to smelt at a time. Players can even place different materials in a furnace, allowing them to smelt multiple different types of ore at the same time.
