Magma Crucible

Yes, it can make lava. You monster.

The Magma Crucible is one of the Machines added by Thermal Expansion. It uses Redstone Flux to melt down solid materials into fluids. This often takes a large amount of energy. The Machine is required to create most of the fluids in Thermal Foundation.


Shaped Crafting


When working at maximum speed, the Magma Crucible consumes 400 RF per tick. When its internal energy storage is starting to deplete, the Machine will slow down and use less power. This prevents sudden interruptions of the Magma Crucible's work when its power supply cuts short.

The Magma Crucible is currently the Machine in Thermal Expansion that can consume the most power, consuming up to 8000 RF per tick with all three Processing Speed Augments installed.

The different sides of the Magma Crucible correspond to different color-coded slots and tanks in its GUI. These sides can be identified by color-coded openings in the sides of the Magma Crucible. This is used for handling input and output with ducts/pipes/conduits/tubes, other Machines and other types of inventories and/or fluid tanks.

If the Integrated Modular Framework Augment is installed, this feature of the Magma Crucible can be configured. Some things can be inserted from any side.

If the Integrated Servo Mechanism Augment is installed, output fluids are automatically ejected from the corresponding sides of the Magma Crucible, evenly divided between the available outputs.

If the Integrated Hopper Apparatus Augment is installed, input items are automatically pulled into the Magma Crucible from adjacent inventories at the corresponding sides.

Type Color Default Sides
Item input Blue Top, Bottom
Fluid output Orange Left, Right, Back
Any item input/output* (colorless) (not set)
Redstone Flux input - (any side)
*: Cannot be automatically ejected from.


The following table lists the recipes that the Magma Crucible can perform. Recipes that use less energy also take less time.

*: May be changed or disabled in the config.
