The Igneous Extruder is a Thermal Expansion machine which uses Lava and Water to create Cobblestone, Stone or Obsidian.

Infinite Scrap Generation

Because it is self-powering and can produce Cobblestone indefinitely off a single bucket of Lava and Water, the Igneous Extruder is an ideal machine for producing the Scrap needed to lessen the EU cost of each UU-Matter.

The following link is to a tutorial on how to build a scrap generation rig using Igneous Extruders: available here (also in video section below)

While Cobblestone is free, all recipes require at least 1 full bucket (1000 mB) of Lava and Water in the machine.
