Slime is a toxic biomass that is found in the Swamp biome and Ruins. The tiles can be mined, and can leach germs onto adjacent tiles. Mined balls of slime are also generated by Pufts consuming Polluted Oxygen.
If Slime is not under a pressure of 1.8kg/tile it converts slowly into Polluted Oxygen (42.5 g/s) at a mass rate of 1:1. Slime stored in the open, in storage, submersed in liquids or under solids without enough pressure will convert.
Danger 
Edit
Slime is often infected with Slimelung Germs and any Polluted Oxygen created will also be infected.
Until you have researched Algae Distillers and ways to deal with Polluted Oxygen you should NOT mine towards slime or areas where Pufts live.
Uses Edit
Algae Distillers can be build to convert slime into algae.
Heating Slime above 125 degree Celsius transforms it into dirt.
Slime is used to farm Dusk Caps which consume 4kg/cycle and reduces the growth period from 40 to 10 cycles.
