Where to Find Lava

Lava occurs naturally deep underground in the Lava Cave. Deeper caves may expose larger orange pools beneath Ice layers, behind Shatterstone, or inside open chambers, but world generation means there is no fixed route.

When you see a new pool's glow, stop before breaking through. Prepare containment and keep Snow or a Cryoblaster ready if you need to solidify the flow.

What Is Lava Used For?

Module 01

Automatic Burning

Contained Lava can ignite burnable pixels passing over it, including supported Residue and Flower setups.

Module 02

Heat and Thermal Buffers

Direct Lava contact or rising flames can provide heat. Some heat setups may gradually consume Lava.

Module 03

Making Steam

Water landing on Lava becomes Steam. This specific reaction does not reduce the Lava.

Module 04

Smelting and Exploration

Lava can provide heat for smelting contexts, melt Ice, and appear in exploration puzzles.

Consumption depends on the use: turning Water into Steam does not reduce Lava, while a recent guide reports gradual consumption in some Thermal Buffer and burning setups.

How Lava Works

Lava, Scoria, and Cinder

  1. 01Lava + Snow
  2. 02Scoria
  3. 03Break Scoria
  4. 04Cinder
  5. 05Ignite
  6. 06Lava

A Cryoblaster can provide Snow. Breaking the resulting Scoria drops Cinder, which can travel through solid-material systems such as Conveyor Belts and Launchers.

How to Get Access to Lava

If the natural pool is near the machine that needs it, contain and use Lava at the source. If it must return to your factory, freeze it into Scoria, break the Scoria into Cinder, and transport the solid material.

There is no confirmed Factory Level, Objective, or Research point for first access to Lava.

How to Handle and Store Lava

Contain Liquid Lava

Build a solid-walled chamber and seal every side. Filters can help control what enters from above.

Store Cinder for Later

Cinder is often the more practical storage form. Keep a visible stockpile and filter Sand, Residue, and Snow out of the conversion area.

Manage Steam and Heat

Give Steam a controlled route with Walls, Filters, or Vents. If Lava supplies heat, watch both the chamber level and output.

Common Lava Handling Problems

Problem 01

Lava Leaks from the Chamber

Inspect every wall pixel and seal the gap before adding more Cinder or Lava.

Problem 02

Raw Lava Will Not Travel on a Belt

Convert it to Cinder first. Conveyor Belts transport solid Cinder, not raw Lava.

Problem 03

Snow and Water Create Ice Clogs

Keep Snow separated from Water lines and filter it before the materials combine.

Problem 04

The Heat System Runs Out

Keep a Cinder buffer nearby and monitor the Lava level. Heat systems may need top-ups.

Problem 05

Steam Escapes into the Factory

Enclose the reaction area and give Steam an intentional route.

No specific game build or Demo comparison is confirmed. Direct-flame conversion and Lava consumption in heat systems are documented mainly by one recent guide, so treat those details as setup-specific rather than universal rules.

How to Move Lava

Freeze raw Lava into Scoria, break it into Cinder, transport the Cinder, and ignite it inside a sealed destination chamber.
