Solid Chlorine is an element that can be obtained in the base game from the Chlorine planet on the Starmap. It serves as a chlorine-related resource in the broader resource set, but the provided sources only confirm its source of acquisition rather than any deeper crafting or use details.
Because it comes from a specific Starmap destination, Solid Chlorine is tied to space exploration rather than early terrestrial production. Players looking to stockpile it must reach the Chlorine planet and bring it back through their usual interplanetary logistics.
