Magma Crucible

Magma crucible

Yes, it can make lava. You monster.

A magma crucible, or crucible for short, is a machine that melts items into fluids.


A placed magma crucible can be instantly picked up by dismantling it with a wrench. Its configuration is preserved in the item. It can also be mined using a pickaxe, though this can be much slower.



A magma crucible is initially at the lowest tier (basic). It can be upgraded to higher tiers using upgrade kits and conversion kits.



When placed, a magma crucible faces the player. It can face any of the four cardinal directions, and can be rotated using a wrench.


When items are placed in a magma crucible’s input slot, the machine will start consuming Redstone Flux to process them. Every item requires a certain amount of energy to process. When enough energy has been consumed for an item, the input is consumed and the output is placed in the output tank.

The speed at which a magma crucible processes items depends on how much energy it can use per tick. This in turn depends on how much power is being supplied, and on the machine’s maximum power usage. A basic crucible has a maximum power usage of 50 RF/t. This can be increased by upgrading the machine to a higher tier, and by installing certain augments.

Input and output

Items and fluids can enter and exit a magma crucible through its sides. Every side of a crucible may correspond to its input slot, its output tank, or both at the same time.

A magma crucible can automatically transfer fluids out of any sides that directly correspond to its output tank. This is called auto-output. It can also transfer items from adjacent inventories into any sides that directly correspond to its input slot. This is called auto-input. Auto-output and auto-input occur whenever the machine finishes processing an item, or every 32 ticks (1.6 seconds) if the machine is inactive.

A basic magma crucible can automatically transfer up to 16 items and up to 1,000 mB of fluid at a time. These amounts can be increased by upgrading the machine to a higher tier.

Which sides correspond to which slots/tanks and whether auto-output and auto-input are enabled can be configured using the Configuration tab in the machine’s GUI.

Redstone control

A magma crucible may be configured to respond to redstone signals. It can be in one of three modes:

Redstone control is disabled. The crucible works whenever possible. This is the default mode.
The crucible works when not powered. When powered, it stops working.
The crucible only works when powered.

The current mode can be set using the Redstone Control tab in the machine’s GUI.

When a magma crucible must stop working due to a redstone signal and is still processing an item, it will finish processing that item before stopping.


A magma crucible can have a signalum security lock installed to restrict who can access it.


A magma crucible’s configuration can be saved on a redprint to be copied to other crucibles.

Light source

When a magma crucible is active, it emits a light level of 14.


Magma crucibles come in five tiers.

Tier Max. power usage Augment slots Max. items per auto-transfer Max. fluid per auto-transfer
Basic 50 RF/t 0 16 1,000 mB
Hardened 75 RF/t 1 16 1,000 mB
Reinforced 100 RF/t 2 28 3,000 mB
Signalum 125 RF/t 3 44 6,000 mB
Resonant 150 RF/t 4 64 10,000 mB


A magma crucible can have augments installed to improve certain properties or to change how it works. The amount of augments that can be installed depends on the machine’s tier. A basic crucible cannot be augmented.

Augments can be installed in the Augmentation tab in a crucible’s GUI.

Augment Installable in Description
Auxiliary Reception Coil Auxiliary Reception Coil Any machine Increases a machine's maximum power usage (speed). However, also increases the amount of energy required per operation. Can be installed multiple times.
Pyroconvective Loop Pyroconvective Loop Magma Crucible A specialization that increases a magma crucible's maximum power usage (speed) by a factor of 10. However, a crucible can only produce lava when installed.
