Crude Blast Furnace

The Blast Furnace is a block added by Immersive Engineering. It is a multi-block: it must be arranging it in a 3x3 solid cube to work. After it is arranged in that pattern, the player must right-click one of the center blocks with an Engineer's Hammer, then the multi-block is complete.



The Blast Furnace works much like a normal Furnace, but it is only for making Steel. Coal Coke or Charcoal can be used as a fuel. One Coal Coke is the perfect amount of fuel to smelt one Iron Ingot.

A Block of Coal Coke can be used as fuel, with 11.11% extra efficiency. A Block of Iron can be used instead of an Iron Ingot, although it doesn't have any extra efficiency except for time.

Bugs
In version 0.3.3 and before:
 * Charcoal (block or otherwise) cannot be used.
 * One Coal Coke is one tick off from being able to smelt one Iron Ingot.
