Oxylite

Oxylite is a solid mineral resource found in Oxygen Not Included that passively emits Oxygen when exposed to open air. It commonly appears as veins or deposits in certain biomes and ruins and serves as an early-to-midgame Oxygen source that can reduce reliance on Algae-based methods if managed properly. Oxylite emits clean Oxygen (not Polluted Oxygen) as it sublimates, so it bypasses Slimelung concerns associated with some other natural Oxygen sources.

Oxylite behaves like other sublimating solids: when exposed (dug up or otherwise placed in an open tile) it will gradually lose mass while producing Oxygen gas. Sublimation continues while Oxylite sits in a Storage Bin unless the tiles above are pressurized; storing Oxylite submerged in a liquid or under at least 1.8 kg/tile of gas prevents sublimation and preserves the material. Because sublimation reduces the Oxylite mass, compacting and storage logistics are important for long-term use.

Practical usage and behavior notes:

• Oxylite provides clean Oxygen and does not produce Polluted Water or Polluted Oxygen byproduct; it is therefore a straightforward air source for closed rooms and early colonies.
• Store Oxylite submerged in water or under sufficient gas pressure if you want to keep it from producing Oxygen immediately. Submersion is the most reliable prevention method but requires layout planning.
• Oxylite in hot environments can change behavior like other materials that have temperature-dependent state changes; be mindful of ambient temperatures when using Oxylite near thermal hazards or heat-generating buildings.
• Sublimating Oxylite can cause over-pressurization if large quantities are left exposed in confined spaces. Monitor gas pressure and provide ventilation to avoid unwanted pressure build-up.
• Oxylite is best used as a supplementary or emergency Oxygen source rather than the sole long-term supply for large colonies; it is valuable for jump-starting life support or for small, controlled rooms.
• When harvesting natural Oxylite veins, take care not to disturb temperature regulation in adjacent biomes (for example Abyssalite seams or Volcanic neighbors), and plan for containment to capture the released Oxygen efficiently.

Acquisition:

• Oxylite appears as natural deposits in the world generation and can also be found in certain ruins and POIs. It can be harvested with normal digging operations.
• Some Space POIs can yield organic and mineral resources; check mission loot tables if attempting to collect Oxylite or similar materials during rocket expeditions.

Because Oxylite produces breathable Oxygen without generating polluted byproducts, it is a convenient building-block resource when creating breathable rooms, emergency shelters, or compact bases where Algae or Electrolyzer infrastructure is impractical. Plan storage and ventilation to control its sublimation and to avoid waste or over-pressurization.
