The blast furnace is a lava/solid fuel-powered furnace used to create different alloys out of two inputs. It was formerly known as the alloy furnace.
Crafting
The blast furnace can be crafted in an anvil with the following recipe:
A blast furnace extension is also generally desirable to craft, for increased fuel efficiency and processing speed:
Usage
The blast furnace takes two compatible items in the top and bottom slots (order does not matter) and can be powered by a lava bucket or certain solid fuels on the slot of the right.
It can accept materials in ingot/solid or powder form: however, it is more fuel-efficient to combine powders inside a crafting grid beforehand, and smelt the alloyed powder some other way.
A separate block, the blast furnace extension, can be placed on top of the blast furnace to make it operate faster. Without the extension, it smelts items at about half the rate of a furnace; the extension triples that rate. Fuel consumption remains constant, meaning the extension also triples the efficiency of fuel consumption.

The blast furnace has relatively few recipes, but most of them are crucial to progression in the mod:
- Steel = Iron ore + Coal
- Steel = Iron + Coal (produces 1)
- Red copper = Copper + Redstone
- Advanced alloy = Steel + Red Copper
- Napalm = Diesel canister + Slimeball (produces 1)
- Magnetized Tungsten = Tungsten + Schrabidium nugget (produces 1)
- Neutron Reflector = Tungsten + Coal
- PaA Alloy Plate = Mixed Plate + Gold plate
- Starmetal = Saturnite + Meteorite powder
- Technetium Steel = Steel + Technetium-99 nugget (produces 1)
Fuels
The blast furnace can accept alternative fuels over the non-renewable lava. Most are high yield solid fuels like coal, coal blocks, solid fuel, coke, and charcoal. The fuel storage takes a lot of coal/charcoal to reach its approximate maximum, a whopping stack of 64 (or ~6 coal blocks). Blaze rods (~12) and powder (~42) are also accepted, meaning that access to a nether fortress can secure quite a lot of blast furnace fuel;
Notes
- It will grant the player the Bobmazon "Metalworks" achievement when crafted.
- A bucket of lava will fill it to the top with fuel, so even if the furnace has just a tiny amount of fuel in it, it won't accept it.
- All of the alloying recipes can be made much faster in the crucible.
Trivia
- In older versions, the "alloy furnace" accepted charcoal as an alternative to coal in the recipes. Coal was thus only an ingredient, and charcoal only a fuel.
Nuclear Blast Furnace

The nuclear blast furnace is an RTG-powered alternative to the standard blast furnace. It has 6 slots for RTG pellets, and requires a minimum of 15 heat to operate (the equivalent of 3 Plutonium-238 RTG pellets). It is significantly faster than the regular blast furnace.
Pellets with higher power levels will have a better effect of heating and thus speed : if sufficient heat is provided, it can alloy items near-instantaneously.
