Modern artillery rounds obviously use smokeless powder.
At Ft. Sill, I heard one old sergeant talking about using a couple of handfulls of water into the powder to produce a large volume of smoke - for a fire-power demonstration.

So, there is SOME validity to a portion of the smoke being steam.

When shooting my 10 pounder Parrott Rifle at re-enactments I usualy added one heaping cup of flour in a seperate baggie on top of 12 oz. of powder.  I tried it with and without the flour.  I can't tell you it ever made any difference.  I certainly never could tell any difference in the noise.  For some reason I still did it. ???  Habit I guess.

as a kid we'd blow flour out of a straw across a birthday candle . Nice whoosh !

Every year at New Years we have a large fire and shoot large quantities of fireworks to ring in the new year.  What would happen if a cannon loaded with the charge described above was fired across the fire?  Large fireball?

Large fireball?

Maybe.  Maybe blow the fire all over the place, too.  Something to try without a lot of people around first.

I don't think I would want ot be loading black powder into a cannon that was that close to a large fire...

"... it seemed like a good idea at the time" comes to mind.

One fellow uses corn starch and a primer (on another board, in a pistol) to make a 'smoke' round with little report.

This brings to mind an article of some years ago , a fellow looking for extreme velocity compressed corn starch into a jacket for a handgun . I wonder if a corn starch ball would give a bang and then shatter ? Armorer77

Any kind of combustible particle that can be dispersed in air will become a good fuel/air explosive.  The quantity of material burning causes rapid expansion of the air and will build enough pressure to explode a grain elevator.

I think this Myth Busters experiment with "non-dairy coffee creamer" pretty much proves GG's statement. :o

RIP John. While on vacation July 4th 2013 in northern Wisconsin, he was ATVing with family and pulled ahead of everyone and took off at break-neck speed without a helmet. He lost control.....hit a tree....and the tree won.  He died instantly.

The one thing that you can almost always rely on research leading to, is more research.

Hi
I've tried a lot.
No wads, can give a bad burn with bad sound,
with wads, get a better combustion and better bang.
The reason why I often use the flour is that it is easy to pour in.
I have good results using the isolation rocwall
Of course, you will get higher pressure, which provides higher sound.

But a little warning.

Use of wet paper, then the weight will be high, and very high pressure as a result.
I do not like to see them filling barrel with a wet paper without the control weight,
that's when accidents can happen.
