Separate burning slag from processing burnt slag.

Community discussions describe burning slag with heat and then routing burnt slag onward. The Kinetic Slag Press entry describes a later processing role; exact recipes remain build-sensitive.

01

Definition

“Slag burner” is community shorthand for the heat stage.

The captured Steam discussion says lava can be placed inside a filter so slag passing over it cooks automatically; a developer reply calls it an autoburner setup. Treat this as Community behavior for that build, not an official blueprint.

02

Use sequence

Keep burning and pressing as two separate stages.

Slag→Lava + filter heat stage→Burnt slag→Kinetic Slag Press→1 Gold + 1 Spore

The captured publisher wiki entry says the Kinetic Slag Press turns 1 Burnt Slag into 1 Gold and 1 Spore. That numeric recipe comes from an inferred wiki entry, not an official first-hand test; confirm it in the current Early Access build.

Layout guidance

Separate the hot zone, recirculation check, and press feed.

  • Contain lava inside the filter area described by the discussion.
  • Let slag pass over the hot zone rather than mixing lava into the main feed.
  • Keep a route for burnt slag to leave toward the press.
  • The discussion suggests recirculating uncooked slag that slips through; test that failsafe with a small batch.

04

Scope

No first-hand recipe or ratio claim.

The lava-and-filter behavior and recirculation suggestion come from one captured Steam discussion. The press role comes from the captured publisher wiki entry. Reproduce both in the current build before relying on the layout.

Questions this page can answer

Is slag burner an official machine name here?

This page uses it as community shorthand for the heat stage.

Are exact outputs verified?

The 1 Gold plus 1 Spore output comes from an inferred wiki entry, not an official first-hand test; recheck it in the current build.
