How would a flour bomb work in Pathfinder?

[Icy Turbo]

Hello everyone! I have been trying to determine how a flammable flour bomb would work in Pathfinder, as I know in the real world flour or other high density powders can ignite and create giant flames given the ability to. How would this translate to Pathfinder? Would it even work? And how much would I need at minimum to damage an enemy with it, and how big could I make it?

Flower bomb: the ultimate tuxedo mask effect...
As for a flour bomb, I think an enclosed space is required... Making it unsuitable as an adventurer etfect. I think this would be an environmental hazard, like swamp gas.

Also, the flour back then wasn't ground fine enuf.

It doesn't.

Try any number of damaging alchemical items for a similar effect. At best I might allow it to cause 2d6 fire damage, similar to some firework listed in alchemical weapons.

Thanks for all the input guys! Would anyone have suggestions of mundane materials that could be used in damaging ways?

Flour bombs are the trick to understanding low-order explosives. It's just something flammable that's spread out into the air enough and fine enough to burn all at once, so fast it creates a concussion wave.

Next popular low-order explosive on everyone's list? Gunpowder. An alchemical item (in pathfinder terms) of course, but you can make kegs of the stuff with the right feat, and for darn cheap.

Flour tossed on the floor makes trouble for invisible people, but that's not directly damaging. If you want weaponized chemistry and physics you're generally going to be buying or crafting alchemy.

Anything lower than that is low-level stuff of limited power, but it's all in how you look at it. As a psychotic halflingwise man once said, "when in doubt, set something on fire." Lamp oil isn't a combat-round weapon, but you can carry a gallon of it for a few gold and that's more than enough to set some really big fires while you run away/bait an enemy.

Personally, I just grab a few kegs of gunpowder, strap them to a few animated halfling skeletons, and keep them in a magic bag until I need a little ground-bound cruise missile.
