Direct answer
Lava is a current liquid entity, while Scoria and Cinder are also present in the current material index. The official guidance describes freezing Lava for solid transport and heating it again later, so design the route around controlled phase changes instead of moving exposed liquid across the whole factory.
Field note
Prepare a contained thermal area
Separate Lava handling from ordinary walking and mixed-material paths. Leave room to stop input, cool the material, remove an obstruction, and inspect the state before it reaches the next process.
A barrier is useful only if it also prevents overflow into unrelated production. Test a small amount before scaling the source.
Field note
Freeze, transport, and reheat
Use the current game's cooling tool or process to turn Lava into a transportable solid state, then route that material through a controlled lane. At the destination, apply heat only after confirming there is capacity for the resulting phase.
Scoria and Cinder belong to the current entity set, but this guide does not invent a universal conversion rate. Observe the output in the same version before designing capacity around a number.
Field note
Recover from a thermal blockage
Stop fresh Lava first. Determine whether the blockage is still liquid, frozen material, or an unintended product, then clear the safest downstream space before reheating anything.
Avoid alternating strong heating and cooling without observing the result. A phase-handling line should make each transition visible and reversible at a small scale.
