Sandustry Burnt Slag: Current Burnt Residue Guide
Quick answer
Maps the old Burnt Slag name to the current Burnt Residue chain and links to the Kinetic Press setup.
Quick Answer
Burnt Slag is older/common wording for the current Burnt Residue material. In the current official chain, Residue is created from Wet Sand on a Shaker, then ignited to create Burnt Residue. Burnt Residue dropped through a Kinetic Press from at least 25 blocks turns into 1 Gold and 1 Seed.
Use this page as a terminology bridge. For the full current chain, start with the materials guide, then use the Kinetic Press guide for the actual press layout.
How to Make Burnt Residue
| Requirement | Current detail |
|---|---|
| Input | Residue |
| Source of input | Wet Sand dropped on a Shaker |
| Processing | Fire, Lava, Flamethrower, Rocket Launcher napalm, or Pyro Dispenser |
| Output chance | About 1 Burnt Residue per 4 Residue |
| Next machine | Kinetic Press |
| Press output | 1 Gold and 1 Seed per Burnt Residue |
Residue burns, but it does not always convert. Some pixels become Burnt Residue; some are consumed with no output. That makes flow control more important than raw speed.
Automation Notes
The current official Burnt Residue page documents several ignition options:
- Manual ignition with the Flamethrower.
- Rocket Launcher napalm upgrade.
- Pyro Dispenser automation.
- Running Residue over Lava trapped in Filters.
For most factories, the Lava-in-Filter approach is the practical automation bridge because it can sit between a Residue lane and the Kinetic Press tower. Keep the burn zone contained and avoid routing Water or valuable materials through the same space.
Kinetic Press Requirements
Burnt Residue must fall far enough to activate the Kinetic Press. If it falls from too low, it rests on top of the press and blocks later input.
| Press check | What to do |
|---|---|
| Drop height | Give Burnt Residue a 25+ block fall |
| Input purity | Keep non-Burnt Residue out of the shaft |
| Blockage cleanup | Aim angled Launchers across the top to clear stagnant pixels |
| Output routing | Keep Gold and Seed falling out of the bottom into separate lanes |
If the press works once and then stops, look for a stray pixel sitting on top. The Kinetic Press setup page has the anti-jam layout.
Old Names and Current Names
| Old/common wording | Current official wording |
|---|---|
| Burnt Slag or Burned Slag | Burnt Residue |
| Slag | Residue |
| Kinetic Slag Press | Kinetic Press |
| Spore from pressing | Seed |
| Wet Spore | Wet Seed |
These old terms are useful for search, but the current pages use the official names so filters, tables, and relationship cards stay consistent.
