Ammonium Perchlorate, roughly half a gram

[iwasapenny]

This is whistle mix, not AP.

[Libertarianist]

Must be very impure.

[adriiPortillo]

this cant be ammonium perchlorate.. only ammonium permanganate burn on its own.

[LETYRONE]

Ammonium Perchlorate by itself does not burn at all. in the video it looks like he used some kind of reducing agent like Al or Mg.

[donnelrj01]

@LETYRONE

I would bet that this is whistle mix.

No commercial fireworks use AP that I'm aware of.

[WEDFED908]

Ammonium Perchlorate does burn by itself and in the video he ignited what appears to be whistle mix since he said he got it from a firework

[v1los]

I'd be very surprised if that was AP in your video. AP does not burn that quickly with any fuel. Plus AP is seldom used in fireworks cos of the cost.

[propyropower]

awesome vid - youre voices sounds like that karakter in postal :O

5*

[ILOVESUBLIME222]

potassium perchlorate and magnalium or potassium permanganate magnalium flash is the best and one of the most dangerous.

[o0Dreamlike0o]

Try KClO3/Al, 70/30. Your Al should be the finest of all 0.o

[murdoch2486]

how well does Ammonium perchlorate work in a flash powder comp, with say Al? cheers

[potassiumperchlorate]

This can't be pure Ammonium perchlorate, since it is only an oxidizer, there must be a reducing agent mixed in to the oxidizing agent.

[MDHmodder]

lol noob

[TheFluorineMartyr]

.... and what, pray. do you make of the NH4 ion?

2NH4ClO4 -> N2 + 2HCl + 3H2O(g) +2.5O2.

You are aware pure Ammonium Detonates? This compound is similar.

[potassiumperchlorate]

The NH4 ion does not exist in a free form.

Only oxidizing ammonium salts have the property of detonating by a shokwave, non-oxidizing ammonium salts don't.

Pure ammonium does not exist, ammonia gass does exist. Ammonia can not be detonatet either.

And again: ammonium perchlorate will never burn of its own on normal sercomstences. AP will only consume itself at high temperture and presure, still it won't detonate if critical mass is not reached.

[TheFluorineMartyr]

I was not disputing that NH4ClO4 shouldn't deflagarate at this pressure when pure, merely addressing your comment that it was "only an Oxidiser"

I was just highlighting that a reducing agent is present.

Ammonium compounds exist in equilibrium - I am aware.

[punishedexistence]

I suppose you could, but perchlorate has more oxygen to supply than nitrate does, plus perchlorate is more reactive. Honestly, I've never tried AN with flashpowder, so I can only guess. Still, I'm sure that ammonium nitrate would do the job in a pinch, as long as it's completely anhydrous.

[ILOVESUBLIME222]

ammonium nitrate+magnesium powder works great but as soon as you add the metal powder to the AN it starts SSDR and giving off lots of ammonia vapor, probably not a good idea to store or make AN+Mg devices before you are going to use them.

[IAintNoHick]

little question. Instead of a potassium perchlorate and aluminum flashpowder, could you supplement the potassium perchlorate with ammonium nitrate and get a more powerful flashpowder

[nitrex]

It will take a high temperature to set off that composition due to the stability of Ammonium nitrate. Even ANFO does not go off without a powerful shockwave or a high temperature.

[FreerunRussell]

and thats what mg ribbon is for lmao jk

[nitrex]

magnesium takes too long to burn if you ever tried it with a lighter. Even a zippo takes long, this is why i couldn't get my thermite going.

[LETYRONE]

you are using wrong mesh size.

[kcnkickthecat]

Pure AP won't sustain a flame below 20 bar, add aluminium and it will burn down to vacuous conditions... good experiment though, 5*

[punishedexistence]

Yeah, I'm quite sure it wasn't 100% AP, I'm guessing there was some powdered sugar or something to be oxidized in there. Still, thanks for the comment!!

[kcnkickthecat]

No problem, by the look of it it may be whistle mix.

[simonmic001]

ya lol

[fantactical]

lol:P

[stoffel123]

AP will deflagrate without additional fuel/reducing agent, but not that fast when u barely touch it with a flame.. this stuff is obviously mixed with a fuel, also because the pure oxidizer wouldnt work as rocket fuel, tough it can deflagrate on its own. and like someone stated before it looks like whistle mix (potassium perchlorate and sodium benzoate or salicylate), because there are not much white colored fuels which are used in commercial pyrotechnics..

[stoffel123]

its also correct that they most likely wouldnt use expensive AP as oxidizer for cheap chinese bottle rockets, which i suggest that this stuff comes from. afaik its only used in bigger model rocket engines

[stoffel123]

and they use it in military rocket engines or spacecrafts of course (like the space shuttles solid booster rockets), but not firework rockets

[stoffel123]

one more thing: i had it wrong, AP can NOT deflagrate on its own, it needs a fuel for that.. but it WILL decompose rapidly when heated above 200°, and thats what happened at pepcon

[punishedexistence]

You know, you are probably right, the flame does have a bright yellow cast to it, probably from sodium benzoate. I just got it out of a big fireworks rocket, and now that I've experemented with it a bit, it obviously is not pure ammonium perchlorate, or even the ammonium salt, as someone else suggested, it may be potassium perchlorate.  Nonetheless, it still makes for a nice flash of pyrotechnic goodness. Thanks for all your comments.

[icelez]

Hey is AP good for Plants

Rich in Oxygen and Nitrogen is there harmful Ingredients in it also

[stoffel123]

i dont think so, chlorine is usually bad for plants.. some chlorates are used as weedkiller, i guess perchlorates will have the same effect.. but ammoniumnitrate is a very good and often used fertilizer

[icelez]

Thank You for the Info = )

[Taydrum]

i think that might be whistle mix

[rgsgww]

just imagine millions of pounds of that...search "pepcon"

[punishedexistence]

Oh yeah, I've seen that one. You'd swear that there was a nuclear bomb in there. And I don't even think there was any oxidizers in there either. Yeah, I should try a little aluminum powder, but I don't wanna burn the house down. Wait till summer...

[rgsgww]

yeah i read about pepcon... you could go to wikipedia and search pepcon if you want... they made the oxidizers for rocket fuel and ever since the challenger rocket failure they kept making it and stockpiling the oxidizers up...there were no real way to extinguish a large fire there...if a big one broke out near the oxidizers...they basically had to get out of there and let it explode

[Eachonset630]

Try it with aluminum.

[crazyboy0602]

WHAT?? you have no knowledge of chemistry or fireworks why would you think the stuff you dug out of a rocket was ammonium perchlorate AP is a oxidizer it supplies oxygen it doesn't burn on its own.

[punishedexistence]

Well, not to sound pedantic, but I have a degree and experience that says I do know what I'm talking about. And who says I'm telling the truth anyways about the rocket. I also said that there was possibly powdered sugar for the AP to oxidize in there. All I can say is that it was just a test to make sure my camera worked. And for the record, Ammonium perchlorate will deflagrate with no additional oxdizing material. I know. I found out the hard way.

[crazyboy0602]

you think commercial fireworks companies actually use sugar in their rockets or for that matter expensive ammonium perchlorate? hell not they just use black powder or whistle mix. ammonium perchlorate will NOT deflagrate on its own w/o oxidizing material because it IS oxidizing material.

[punishedexistence]

I know I could go on all day, but let's just say I know the composition of my reagents. I agree, an oxidzer may not be as aggressive in pure state as one that is mixed with a suitable oxidant, but hey, the stuff will go boom if compressed and personally, it works for me. Oh well, thanks for your input regardless.

[gobidee]

if you obtained it from a whistle rocket it would be potassium perchlorate and sodium benzoate

[Elemental235]

looks like a meth lab lol

pretty fast burn time though

[punishedexistence]

Well, no meth, but yeah, it does flare up pretty fast. It's actually pretty old stuff, it was from a huge bottle rocket I got a long time ago when fireworks wwen't as regulated. I'm almot positive there's powdered sugar added as an oxidant, but maybe not. I got about 5 grams left, maybe I'll make something cool out of it.
