The Iron Furnace is a machine in IndustrialCraft 2 that functions as a faster and more fuel efficient version of the vanilla Furnace.


Pre 2.0 (Minecraft 1.6.2 and below)

This information pertains to an older version of the mod.


The Iron Furnace GUI

The Iron Furnace's GUI

Like the vanila Furnace, the top slot in the Iron Furnace GUI is the input slot; whatever material that is being smelted goes there. The bottom slot in the GUI is the Fuel slot; the Iron Furnace, unlike most IndustrialCraft 2 machines, does not operate using EU, but rather by burning Fuel like a vanilla Furnace. Lastly, the slot on the right is the output slot; smelted materials will be placed there upon completion.

The Iron Furnace is 25% more fuel efficient than the vanilla Furnace, and also 20% faster. Lava based fuel sources are only 10% as efficient in an Iron Furnace as they are in a vanilla Furnace.

When used in conjunction with Buildcraft Transport Pipes or RedPower 2 Pneumatic Tubes, any material for the input slot needs to come from the top of the Extractor, while anything for the Battery slot should come from the bottom. Output can be taken from the sides of the machine.

Fuel/Speed Comparison

A vanilla Furnace uses 200 Heat Units and takes 10 seconds to complete one smelting operation, while an Iron Furnace uses 160 Heat Units and takes 8 seconds to do the same.
