Blast Furnace (Railcraft)

The Blast Furnace is a multiblock structure added by Railcraft. This structure is used to turn Iron into Steel. The Blast Furnace will only take Coal Coke and Charcoal as fuels, requiring 1 Coal Coke per ingot, and 4 Charcoal per ingot.

To build the structure, 34 Blast Furnace Bricks is required. It is built by placing the bricks in a 3x3x4 with a hollow middle. Once assembled correctly the Blast Furnace will have a window on the bottom-middle of each side. When this furnace is active it will contain lava in the middle; breaking it at this time is, accordingly, dangerous. Blast Furnaces cannot be built directly adjacent to one another; there must be a gap between them, or other (non-blast-furnace) blocks. Though, it may be built directly adjacent to other multiblock structures.
