Gel

Gel is a basic resource in Stellaris: Galaxy Command. It can be collected by workships from deposits inside sectors that contain gel.

Alternatively, once upgrading the station nexus to level 10, the resource forge can be built. The resource forge will produce gas as long as the players station is located in a sector that contains gel.

Uses
Gel can be used alongside alloys and gas in a chemical refinery to produce chemical motes.
