Material Settling Order
When a tank contains several materials, their physical order can determine whether a Filter ever reaches its target. This community-tested table reads from the highest layer to the lowest layer.
Top-to-Bottom Order
| Order | Material | Community classification |
|---|---|---|
| 1 — highest | Steam / Depleted Steam | Gas; listed on the same layer |
| 2 | Prismaline | Gas |
| 3 | Florin | Gas |
| 4 | Void Seed / Voidbloom / Prismite / Florinol | Liquids sharing one layer |
| 5 | Amethelis | Solid |
| 6 | Dry Amethelis | Solid |
| 7 | Void Petal | Solid |
| 8 | Cinder / Residue / Burnt Residue | Solids sharing one layer |
| 9 | Lava | Liquid |
| 10 | Moonhop | Solid |
| 11 | Water | Liquid |
| 12 | Auralite | Solid |
| 13 | Wet Seed | Solid/slushy |
| 14 | Seed | Solid |
| 15 | Auxrinite | Solid |
| 16 | Sand / Wet Sand / Snow | Materials sharing one layer |
| 17 | Redsand | Solid |
| 18 | Sunsand | Solid |
| 19 | Liquid Gold | Liquid |
| 20 | Liquid Copper | Liquid |
| 21 | Copper | Solid |
| 22 — lowest | Gold | Solid |
A slash means the source places those materials on the same layer; same-layer materials may mix instead of separating cleanly.
How to Use the Table
- Find the lowest, densest output in the mixture.
- Give that layer the first Filter exit at the bottom.
- Remove it before attempting to extract the next layer.
- Keep reacting materials in separate chambers when a shared layer would let them touch.
- Test with the real feed mixture; an empty demonstration tank can hide a blocked outlet.
Same-Layer Materials Need Active Separation
Materials written on one row cannot be assumed to settle into a stable internal order. If the recipe or byproduct creates two of them together, use separate inputs, a reaction boundary or an Advanced Filter rather than gravity alone.
Version and Evidence Limit
The order comes from Bone White’s Material Settling Order Steam guide, updated for v0.5.3. It is a useful community observation, not an official density specification. New materials and physics patches can move entries.
Settling Order FAQ
Should I filter the lightest material first?
Do materials on the same row separate by themselves?
Is this table an official game specification?
Density-first is an outlet rule
The table does not replace throughput testing. It tells you which layer must be given a reachable exit before the next Filter can work.
