Blast furnace

The Blast furnace performs a similar function to the Smelter, although it can't smelt the ores that the Smelter can.
== General information ==
The Blast furnace is used to process certain raw materials into Metal using Coal as fuel. Materials that can be smelted are:
* Black metal scrap
* Flametal ore
The Blast furnace uses approximately 1 Coal every 15 seconds as fuel. It takes 30 secondsOres used to take 31 seconds to smelt, but this was fixed in update 0.208.1. to produce one bar of Metal.
It can hold a total of 20 coal and 10 ores.
== Building ==
It will be unlocked after the player has killed Moder and built an Artisan table.
Blast furnaces can be placed directly onto terrain and stone structures. Currently, they cannot be placed on wood structures but it is possible to bypass this to an extent by terraforming terrain with a Hoe to be in line with wooden floors.
Unlike the Smelter, Blast furnaces have both of their refueling ports to the LEFT of the bar chute.
== Notes ==
* Like other structures that process materials, Blast furnaces are sped up with the passage of time that happens when the player is sleeping.
* The blast furnace while active gives off the Fire effect for about 3 meters from any side (not just the interaction point).
