Nitre is one of those materials you never think about until a recipe suddenly demands four of it. It powers gunpowder, keeps you cool in summer, and feeds a surprising number of character-specific builds. Getting it is simple, but knowing where the dense deposits sit saves you a lot of walking.
Quick answer: Equip a pickaxe and mine smooth boulders — the round, speckled rocks that cluster in rocky and desert areas. Every boulder drops at least one nitre along with rocks and flint.
What you need before mining nitre
A pickaxe is the only requirement. It costs 1 twig and 2 flint, and you can prototype it without any science station, so it is available from day one. Flint comes from the same boulder fields you are about to mine, which means the tool pays for itself almost immediately.
Bring a second pickaxe if you plan a long trip. A single boulder takes several swings, and durability drains faster than most players expect when clearing a whole rocky patch.
Mine boulders for nitre on the surface
Boulders with visible gold veins behave the same way when you mine them, except they hand you gold nuggets alongside the usual rubble. If you are short on gold for a Science Machine or a Birdcage, those are the ones to prioritize.
Nitre stacks to 40, so a single trip through a decent rocky biome can cover your needs for a long stretch of the game.
Every nitre source in Don’t Starve Together
Surface boulders are the fastest early option, but they do not come back. These are the other places nitre shows up once you have stripped your local rocks.
| Source | Tool | Notes |
|---|---|---|
| Boulder | Pickaxe | Guaranteed at least one nitre per boulder, alongside rocks and flint |
| Cave earthquake | None | 20% chance for falling debris to be nitre |
| Moleworm burrow | Shovel | 20% chance per dug burrow; the mole rebuilds it if left alive |
| Petrified tree | Pickaxe | Found in petrified forests |
| Nitre Formation | Pickaxe | Dedicated nitre deposit |
| Wilson transmutation | None | 2 gold nuggets into 1 nitre with the Transmute Ore II skill |
Boulders in meteor fields are also worth a detour, since meteors keep dropping fresh rock there long after your starting biome is picked clean.
Note: Digging a moleworm burrow while the mole is out at dusk or night leaves the creature alive, and it will build a new burrow you can dig again. Killing the mole ends the loop.
Why earthquake nitre disappears before you grab it
Slurtles and Snurtles emerge from slurtle mounds after an earthquake specifically to eat the rocks, flint, nitre, gold, and gems that fall from the ceiling. If you are mining near a mound and the ground stops glittering, they took the loot.
Either clear the mounds first or trigger your earthquakes well away from them. The same appetite applies to Rock Lobsters, which will also happily eat a nitre you dropped on the floor.
What nitre is used for
How much nitre you need depends entirely on what you plan to build. Gunpowder is the biggest sink for boss fights, while summer survival leans on the endothermic recipes.
| Item | Nitre | Other ingredients |
|---|---|---|
| Gunpowder | 1 | Charcoal, rotten egg (Alchemy Engine) |
| Endothermic Fire | 2 | 3 cut grass (Science Machine) |
| Endothermic Fire Pit | 2 | 4 cut stone, 2 electrical doodads (Alchemy Engine) |
| Salt Lick | 4 | 2 boards (Alchemy Engine) |
| Morning Star | 2 | 2 electrical doodads, volt goat horn (Alchemy Engine) |
| Flare | 1 | Twigs, cut grass |
| Booster Shot | 2 | 8 rot, stinger (Alchemy Engine) |
| Winona’s Generator | 2 | Trusty tape, 2 logs (Winona only) |
| Chef Pouch | 2 | 4 twigs, 4 cut grass (Warly only) |
Nitre also works as fuel. It burns for 1.5 minutes, refuels an endothermic fire, tops up Winona’s Generator, and restores 19% to an Ice Flingomatic.
Confirming you actually picked it up
Nitre appears in your inventory as a pale, crystal-flecked chunk and stacks up to 40 in a single slot. If a boulder broke and no nitre landed in your bag, check the ground for the “Pick up Nitre” prompt before walking away, since drops sit loose rather than going straight to your inventory.
Two things commonly explain a missing haul. A creature ate the drop before you reached it, or your inventory was full and the item stayed on the floor. Both are fixed by clearing space and collecting each pile immediately after the boulder breaks.
Once you have a stack banked, the material stops being a bottleneck. Most players end up with far more nitre than they need simply from clearing rocks for stone, and the surplus quietly turns into gunpowder the first time a giant wanders into camp.
