Ammonia

Ammonia is the fluid resource extracted from ammoniacal solution. It is a core resource for much of Aquilo's industry. It is used to produce solid fuel and rocket fuel, which can be used for making heat on Aquilo via the heating tower. It is needed for building ice platforms that are used to build terrain in Aquilo's otherwise mostly oceanic environment. It is used for fluoroketone (hot) and lithium, both core intermediates for most other manufacturing processes on Aquilo.

Ammonia cannot be put into barrels, so it cannot be transported off of Aquilo. As such, any recipe that uses ammonia as an ingredient can only be used on Aquilo.
