Super flash powder and Armstrong's mixture comparison

[rambbo12]

how do you make your armstrong mix what method and do you make it with a match box or pure chems

[ExothermicVideos]

So were all of these compositions prepared using the special method that you told me about?

This video is impressive; it should have more hits.

Ok so i want to know what armstrongs mixture is made of and the proportions its mixed, also how much ferrocium to use. If you would be so kind to share. What are the do's and dont's when making this mixture. Thank you

[matheusfredrich13]

Nice

@dawson01913

No, I haven't even planned to make ETN. What's the difference between a shocktube and det cord? Is it the amount of explosive?

[Stray03]

@Dornier335A Shocktube is a tube that has a light powdering of HE like PETN or RDX on its walls. when you set it off it causes a shockwave to travel down the tube, but keeps the tube intact. The detcord is full of explosive and acts as one when detonated. you can hold shocktube while the detonation wave travels down it, you don't want to hold det cord. If it doesn't kill you, you'll wish it did.

@Stray03

OK thank you =)

My det cord is something between a shock tube an a det cord. It's flat and the explosive is on the walls. But it's definitely not something I want to hold in my hand when it detonates...

@dawson01913

AP is maybe not safer, but probably less sensitive to impact and friction than AM. It sublimes and looses more than half of its weight in 14 days...

[tyler2260]

what is ferrocerium and is the armstrongs mix made of phosphorus and potassium chlorate thnx

[Dornier335A]

@tyler2260

Ferrocerium is an alloy of rare earth metals like cerium and lanthanum, iron and some magnesium.

The AM was made from pure ingredients but the particle size was a bit bigger than I usually use.

[TheDragonoxx]

I wonder if that he flash powder could b used in a blasting cap? Same with armstrongs mix

[Dornier335A]

@TheDragonoxx

HE FP is not a good option in blasting caps because the ferrocerium powder oxidises very quickly. AM could probably be used but it is way too sensitive.

[TheDragonoxx]

@Dornier335A Really? I thought that AM was less sensitive than AP.

[Dornier335A]

@TheDragonoxx

I know that AM is really sensitive to friction: /watch?v=BV0N8GMVy3c

I don't know how sensitive AP is but it's not the best option either.

[TheDragonoxx]

@Dornier335A Wow, that is sensitive. That actually happened to me while i was mixing some, i wasnt as careful as usual because the amount was so small, and it popped and scared the crap out of me. I do have a pretty safe design for a cap of AM made though. It wont use more than 1.5 grams at very most.

[JaycubL]

@Dornier335A AP is not really super sensitive, that is kindof a myth. If you make it right you really have to hit it hard with a hammer to get it to detonate, and even then only part of it usualy detonates.

[Dornier335A]

@JaycubL

Yeah AP is probably safer to use than AM or HEFP.

[Stray03]

@TheDragonoxx flash powder is never a good option for "blasting caps".

[theguywith1face]

Nice video as usual mate- very informative.

Can you film high speed AM+ ferrocerium, but with the different amounts of ferrocerium to contrast the two? Quite interested after that discussion :)

[Dornier335A]

@theguywith1face

Good suggestion! I might try that when I have time =)

[theguywith1face]

@Dornier335A

Good man. Looking forward to it.

[k3dude]

thanks Dorier335A, I may give a try one day :) 

[tomekkk10000]

Hey i want to ask where you get ferrocerium? I heard this alloy is contained in lighter "stone". But small amounts...

[Dornier335A]

@tomekkk10000

Fire steels are made of ferrocerium.

[k3dude]

equal amounts ?

[Dornier335A]

@k3dude

The armstrong's mix / ferrocerium ratio is not so important.

[MrAde9999]

i vilka affärer kan man köpa tändstål. Då menar jag vanliga affärer som finns runt i hela Sverige t.ex. class ohlson fast där är det ju dyrt

[Dornier335A]

@MrAde9999

Ingen aning =(

[anjin33]

impressive!

[k3dude]

Brilliant vidoe's of the different comps mate, what was the mix of the Armstrong's mixture and the ferrocerium ?

[Dornier335A]

@k3dude

It was KClO3, red P and ferrocerium.
