Crude Blast Furnace - Official Feed The Beast Wiki

The Crude Blast Furnace produces Steel Ingots and Slag by smelting Iron Ingots with Coal Coke or Charcoal as fuel. One Coal Coke burns long enough to smelt one ingot, which produces one Slag piece. A Block of Coal Coke smelts 10 ingots (so it's 11.11% more fuel efficient). A Block of Iron smelts in less time than 9 single pieces.. Coal Cokes come from roasting Coal inside a Coke Oven
