Blast Furnace

Blast Furnace automatically smelts 2 ores into 1 bar (e.g. Ferozium Ore into Ferozium Bar) and has a chance to produce additional materials.

It can only smelt ores of tier 1-5. Later in the game it gets replaced by Arc Smelter, which can smelt tier 6 ores, can smelt Metallic Hydrogen and Deuterium, and also produces more additional materials.
