Blast Furnace
The Blast Furnace is used to obtain  Ultra-Hard Steel . The GUI has 4 slots: the Left Slot is where the combustible ( Lava ) goes, the Upper and Lower Slots are for Input 1 or Input 2 and the Right Slot is for Output.

When putting  Obsidian  in the Upper Input Slot and an Iron Ingot in the Lower Input Slot  Ultra-Hard Steel  will come out. When inserting a  Diamond  in the Upper Input Slot and an  Ultra-Hard Steel Ingot  in the Lower Input Slot  Reinforced Diamond , used to build the  Reinforced Diamond Pickaxe , will come out.
