Bricked Blast Furnace
The Bricked Blast Furnace (BBF) is a GregTech multiblock unlocked in the Steam Age. Its recipes are listed under the NEI "Primitive Blast Furnace" tab. It is typically the first source of Steel Ingots, used for LV Machines and High Pressure Steam Age Machines. It can also increase the yield of certain metal oxides and sulfates (Pyrite, Magnetite, Cassiterite, etc.).
Construction
The Bricked Blast Furnace is constructed by laying a 3x3 foundation of the Firebricks followed by hollow ring of Firebricks above it with the Bricked Blast Furnace (Controller) on front center and another two hollow rings of Firebricks above it.
Attention! Top center block of the Bricked Blast Furnace must be empty.
The BBF can be wallshared. However, it will only allow horizontal wallsharing. The section below explains this in more detail.

Usage
The BBF is the only way to obtain steel in the Steam Age. It can also be used to obtain extra output from metal oxides and sulfates (Pyrite, Magnetite, Cassiterite, etc.). Doing this returns 3 ingots for every 2 dust.
Fuels
- Coal Coke
- Coal
- Charcoal
- Charcoal Dust
- Coal Dust
- Coal Powder
- Cactus Coke
- Sugar Coke
- Block of Coal Coke
- Block of Charcoal
- Block of Coal
- Colored Block of Coal
Note that recipes that use the block form of fuel are typically more efficient; each block is made by compressing 9 fuel items, but often substitutes for 10 recipes (ex. 2 blocks of coal coke and 10 iron ingots can make 10 steel ingots, 20 coal coke and 10 iron ingots also makes 10 steel ingots).

Trivia
- There is lava inside the working Bricked Blast Furnace but it can't be pumped out.
- You can save 8 Firebricks by sharing the walls of the 2xM version instead of 1xM one.
- Although in the interface, input slot #1 has an ingot icon and input slot #2 features a dust icon, either slot can be used for either state of material and in some recipes blocks, such as sand, are used.
- The Steam Age blast furnace of choice used to be the Bronze Plated Blast Furnace, which has since been deprecated.
