ModThermal Expansion 5

The Igneous Extruder is a machine added by Thermal Expansion 5. It uses Redstone Flux (RF) to mix Water and Lava together to create igneous rocks, like Cobblestone, Granite, or Obsidian.

The Igneous Extruder has one input (blue) and one output (orange). These can be changed to different faces using the Configuration menu in the machine's GUI.



The Igneous Extruder has two internal tanks, and will not function unless both tanks have at least 1,000mB of fluid. A button in the center of the GUI cycles through available recipes. When running, the extruder will consume fluids in the tank to produce items using the selected recipe. Some recipes require 0mb of one or both fluids. In this case, those fluids will not be consumed.


An Igneous Extruder can accept the following Augments:

Image Name Type Description

Auxiliary Reception Coil Augment Increases max power usage (speed) at the cost of higher power use per operation. Stackable. Multiplies max power usage by 1+n, and increases power use per operation by (10n)%, where n is the amount of coils installed.

Pyroclastic Injection Specialization Allows the extruder to function without water.

Clastic Deposition Specialization Allows the extruder to produce sedimentary rocks, such as Sandstone or Gravel. The extruder cannot produce igneous rocks.


An Igneous is crafted at the lowest tier (Basic). It can be upgraded to higher tiers using Upgrade Kits. As it is upgraded it is able to use more RF per tick, which allows it to process items faster. Upgrading also adds augment slots, and increases the input and output rate of items and fluids.

Tier Max Power Usage Power Storage Augments

Hardened 30 RF/t 30,000 RF 1
Reinforced 40 RF/t 40,000 RF 2
Signalum 50 RF/t 50,000 RF 3
Resonant 60 RF/t 60,000 RF 4
