Limestone is a non-renewable natural resource found only on the island. It is obtained solely via mining in a Designations. It is a required ingredient for the production on Cement, Glass Mix, and late-game Molten Copper. It can also be used as an input in the conversion of excess Sulfur into Slag, though care should be given to monitor resource levels to avoid exhausting Limestone mines.
