Lava is a confirmed physical material in Sandustry that can be redirected as an alternative way to deal with thick ice, while cryoblaster-produced snow can solidify lava. The official description and supplied gameplay both connect lava to heat, ice, water, and exploration. Exact flow speed, temperature values, damage rules, and production ratios remain 待确认 (to be confirmed).
Lava As An Ice Solution
The official game description says a flamethrower can punch through a thick wall of ice and asks whether the player could redirect lava instead. This confirms lava as a possible environmental heat source or puzzle solution around ice. It does not provide a universal layout or required quantity.
Solidifying Lava
One gameplay transcript describes the cryoblaster as producing infinite snow that can freeze water, solidify lava, or later become steam and rain. That recording confirms an interaction between snow and lava in its captured build. The exact resulting material and whether it can be processed are not clearly documented, so those details are 待确认.
Heat, Water, And Steam
Sandustry's official pixel-physics description says ice becomes water when heated and boiling water rises as steam. Steam can return as rain if it reaches the sky, connecting underground heat to water-supply design. Lava may participate in those systems, but the sources do not quantify its heat range or transfer rate.
Player Safety In The Recording
One demo video states that the player does not take damage and can enter lava or water safely in that recorded build. The Steam feature description does not independently document damage or survival rules. Treat invulnerability around lava as build-specific evidence rather than a permanent guarantee.
Factory And Exploration Risks
Even without confirmed player damage, redirected lava can change nearby ice, water, snow, and terrain. Sandustry's resources interact physically, so an uncontrolled path may affect a production area or block access. The supplied sources do not provide containment dimensions, pipe support, or a formal hazard system.
Verified Boundary
Use lava as a confirmed environmental option for thick ice and recognize that snow can solidify it in the shown gameplay. Do not assume exact temperatures, outputs, immunity, or optimal routing from these sources. Those values and any lava-specific machine recipe remain 待确认.
