Crude Blast Furnace

The Crude Blast Furnace (previously just the Blast Furnace) is a multiblock added by Immersive Engineering. It must be arranged in a 3x3 solid cube of Blast Bricks 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.



Usage
The Crude Blast Furnace works much like a normal Furnace, but it is only for making Steel and Slag (the later as of version 0.7). Coal Coke or Charcoal can be used as a fuel. One Coal Coke is the perfect amount of fuel to smelt one Iron Ingot and create one Slag.

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.

The Crude Blast Furnace is the pre-cursor to the Improved Blast Furnace.
