Poudre Noire in Atomcraft

Poudre Noire was added in the July 29, 2026 update alongside the Blender Gun improvements and Blueprint flipping controls. It is Atomcraft entry-level explosive: a spark-triggered compound made from three readily available reagents, less catastrophic than Nitroglycerine but reliable enough for mining shafts, demolition work, and controlled blast chambers.

Crafting Poudre Noire

Combine the following three materials in a reaction chamber:

Reagent	Notes
Charbon	Produced by heating Wood in a low-oxygen or controlled-heat environment
Nitrate de Potassium	Found as a mineral deposit or produced via the nitrification loop (Nitrogen cycle + Heat)
Soufre	Mined from volcanic or geothermal surface deposits

The reaction is spark-triggered: Poudre Noire will not detonate on its own. Use a heater pixel, flint-spark setup, or the Nuke Launcher controlled blast to ignite it. Once sparked, the explosion propagates through the powder mass rapidly.

What Poudre Noire does

Poudre Noire explodes on spark with a moderate destructive radius. It is useful for:

• Mining shafts - blast through hard rock without the overkill of Nitroglycerine
• Demolition - remove old forge walls or clear blocked passages
• Controlled blast chambers - small, repeatable explosions for moving heavy materials
• Legacy compatibility - Nitroglycerine remains available for endgame destruction

Poudre Noire vs. Nitroglycerine

Property	Poudre Noire	Nitroglycerine
Power	Moderate	Extreme
Trigger	Spark	Impact or spark
Stability	Stable - stores safely	Volatile - risky to transport
Reagents	Charbon + Nitrate de Potassium + Soufre	Glycerin + Nitric Acid
Use case	Mining, controlled demolition	Endgame bulk demolition

Poudre Noire is the gradual step up from pickaxes and drills. Nitroglycerine is for when you need to level a mountainside or carve a new river channel.

How to set up a spark trigger

The simplest spark trigger uses a pixel Chauffant adjacent to the Poudre Noire mass:

1. Place Poudre Noire pixels in the target zone.
2. Adjacent to one end of the powder mass, place a pixel Chauffant.
3. Wire the Heater to a Bouton or Switch so you control the timing.
4. Press the Bouton; the Heater sparks and ignites the Poudre Noire.

For more precision, use a Timer to delay ignition after the Bouton press, giving you time to retreat.

Safety notes

• Store Poudre Noire away from active heat sources until you are ready to blast
• Do not place Poudre Noire adjacent to your main forge - a temperature fluctuation could trigger premature ignition
• Use conveyor locks or filter pixels to move Poudre Noire only when the blast zone is clear
• The explosion does not discriminate between ore and bedrock; plan your blast geometry before pressing the Bouton

Poudre Noire in the July 2026 patch notes

Poudre Noire arrived alongside several other quality-of-life additions:

• Blender Gun now respects islands - blending across a wall will not throw materials outside your forge
• Blueprint flipping with B and N keys for easier mirrored builds
• Spaceship Inventory Hold button - materials with Hold enabled skip the Transfer All pass
• Hypochlorous Acid reactions - no longer a dead-end reagent

Poudre Noire fills the gap between manual tools and endgame explosives. Stock it near your mining fronts, wire it to a controlled timer, and blast smarter - not harder.
