LOCATION
Go deep for the natural source
Current official documentation places natural lava in the deep Lava Cave.
Because the world is procedural, this guide does not publish a fixed coordinate or fake universal map. Use your current exploration and map systems to locate the deep biome in your own seed.
STATE CHANGE
Freeze → break → move → reignite
Treat Cinder as the transport form and lava as the working form.
- 01SOURCELava

STATE ROUTE✓Scoria → Cinder → lava
HEAT / REACTION
Use lava as controlled heat
Current documentation describes direct burning interactions, including material held in filters.
Filter-held burning
Lava trapped in a filter can ignite burnable material that passes through the setup. The filter is part of the material-control logic, not decoration.
Residue and flowers
The documented use cases include automating the burning of Residue and flowers. Keep the heat source contained and the route observable.
LAYOUT LOGIC
Separate transport from reaction
A readable lava system has a cold side, a transfer line, and a hot side.
Make the resource safe to move.
Keep the Cinder route separate.
Restore lava beside the reaction.
VERIFIED VISUALIZATION This diagram explains the documented state logic. It is not a copyable blueprint or a claim about optimal tile ratios.
LEGACY SEARCH TERM
What “Slag Burner” probably means now
The demand is real; the current entity name is not.
Search phrase seen in old or player language. Do not treat it as a current official machine.
Current material names in the official knowledge base.
Current named systems relevant to heat and burning.
FAULT FINDER
Why the lava line stops
01You are trying to put lava into a normal pipe
Use the documented state-change route. Convert lava to Scoria, break it into Cinder, transport the solid, and reignite at the destination.
02Scoria reaches the line but does not move as expected
Scoria is the frozen state; the transport step is Cinder. Confirm the break step occurs before the transfer route.
03The destination has Cinder but no heat
The final state change is missing. Provide the current ignition method at the destination and verify that the hot zone is contained.
04An old guide uses Slag or Kinetic Slag Press
That terminology belongs to older evidence. Re-check the current Early Access names before following the layout.
