Gun powder comes out in batches a single volcano can't finish. Craft one white volcano and half a batch of gun powder stays in your inventory; craft a pair and the batches come out exact. So queue them in twos, or count the spare powder into your next ammo craft.
Only owners of the Steam item see this recipe, and there is no blueprint for anyone to research.
Colour changes nothing in the bill: a red volcano costs the same, so mixed pairs work too. If a white boomer goes up the same night, craft the powder for everything in one queue and round up once, not per firework. The sulfur comes from your raid pile either way.
