How to Move and Transport Lava in Sandustry

Direct answer: do not pipe Lava

Normal Pipe and Pump networks do not transport Lava. Lava also cannot be handled by normal grabbing. The verified workaround is to change the material state: use Snow to turn Lava through Scoria into Cinder, move the Cinder as a solid, then relight it as Lava at the destination.

Do not connect a Pipe and wait for pressure to solve the problem. A Pump touching Lava, an empty Pipe or a Liquid Vent downstream does not change the compatibility rule.

Turn Lava into a movable material

The source conversion should be physically separated from Water lines and valuable structures. Snow touching Lava forms Scoria and then Cinder according to the current official sources, but the transition details are version sensitive. Prove the transformation on a small sample before exposing a large Lava reservoir.

Use this test order:

1. Build a contained source zone with a clear escape route for the player.
2. Remove unrelated Water, Steam and solid materials from the test area.
3. Expose only a small amount of Lava to Snow.
4. Watch for the material-state change rather than relying on the color of a mixed pile.
5. Confirm Cinder can be separated from the hot source zone.
6. Repeat the same small conversion before scaling it.

Water touching Lava can produce Steam. That is a separate reaction, not the Snow-to-Cinder transport route. If Steam appears during the test, first check whether Water entered the source area.

Transport Cinder with normal logistics

Once the material is Cinder, the problem becomes solid logistics. Keep conversion and transport as two visible zones. This lets you identify whether a stopped line is caused by incomplete solidification or by the conveyor path.

Build a short route first:

• Place the collection point beside the conversion area, not inside active Lava.
• Confirm only solid Cinder reaches the first transport segment.
• Use one direct path to an empty destination buffer.
• Leave room to inspect the handoff from the final transport segment.
• Do not add branching, filtering or a long vertical lift until the direct route works.

The current evidence supports the material-state strategy, but it does not establish a best conveyor speed, buffer size or conversion-to-transport ratio. Treat any pile-up as a layout observation, not a universal rate claim.

Before scaling the route, run a handoff test. Stop Snow input, allow the conversion area to settle, and take one visible Cinder batch through the entire transport line. Mark the last point where the batch is still identifiable. If it disappears before the destination, inspect only the next handoff instead of rebuilding the source conversion. If it reaches the buffer but cannot be isolated for ignition, enlarge or simplify the destination buffer. This single-batch test separates material identity, transport continuity and destination capacity.

After the handoff works, resume conversion in short intervals. Compare whether the source produces Cinder faster than the transport line removes it, but record that only as an observation for the tested layout. Do not convert a short run into a universal production rate.

Relight the material at the destination

The destination is a controlled reaction area, not merely the end of a conveyor. Cinder can be reignited as Lava, so the area needs boundaries before the first delivery.

Use three zones:

1. A buffer zone where Cinder arrives and can be inspected as a solid.
2. An ignition zone isolated from the transport machinery.
3. A Lava-use zone that receives the resulting Lava without exposing the incoming line.

The exact ignition tool, action order and safe spacing must be reproduced against the current game version before this route can be presented as a copyable blueprint. The guide therefore gives a safe diagnostic sequence without inventing a fixed geometry.

Keep an emergency stop at the boundary between buffer and ignition. The practical goal is to make the incoming solid line stoppable without entering the active Lava zone. During the first repeat test, pause after every small batch and confirm the ignition area has returned to the expected contained state. If containment depends on material piling in one exact shape, treat the layout as fragile rather than verified.

Late-game Volcanizer route

Current official sources identify the Volcanizer as a later-game way to provide Lava. That can remove the need to carry material from a distant natural source, but this guide does not give an unlock requirement or production rate because those details have not been confirmed for a named version.

Choose between the routes by task:

• Use Snow, Cinder transport and relighting when the problem is moving an existing source through normal factory logistics.
• Consider the Volcanizer when it is already available and the objective is local Lava production.
• Do not assume the later-game route is automatically cheaper, faster or safer without current-version measurements.

Lava transport failures

The Pump touches Lava but nothing enters the Pipe

That is expected. Pipe and Pump networks do not support Lava. Remove the liquid-network assumption and begin with state conversion.

Snow creates a mixed or incomplete layer

Reduce the test volume. Isolate a small Lava sample, remove Water contamination and verify the change through Scoria to Cinder before attaching transport.

Steam appears instead of a clean Cinder route

Water touching Lava can produce Steam. Trace nearby Water outlets, leaking production zones or mixed-liquid paths and separate them from the Snow conversion test.

Cinder never reaches the destination

Confirm it fully left the active Lava area and entered the solid collection point. Then inspect the transport line as a normal solid route: continuity, direction, blocked handoffs and destination capacity.

The destination ignites outside its boundary

Stop incoming Cinder and return to a smaller sample. A working conversion claim does not prove a specific safety enclosure. The destination geometry remains a reproduction requirement.

The factory needs Water and Lava near each other

Keep their transport systems separate and join them only at the intended reaction area. Use the Water guide for Pump, Pipe and Vent behavior, and the Pumps and transport guide to diagnose a nearby liquid network without treating Lava as a supported liquid.
