anybody got a workable process for making the above ?

 

they use a chlorate rp composition coated onto coarse gravel  

 

the chinese have got this down to a commercial process and are literally "banging" them out.

 

they produce a very satisfactory bang when thrown, but do not explode when dropped from ~90cm onto a hard floor.

 

a fine balancing act indeed

You're here with 300+ posts? Do you wonder why nobody's responded to your two threads on friction/impact-sensitive compositions yet? Sheesh, this is not top secret knowledge, but is probably also not a topic of open/public conversation, ffs. Torpedoes and their modern relatives are nothing new. Use your wits, man.

When I was a kid these kinds of fireworks were readily available

They were called Torpedoes and generally came as a silver

painted balls about three quarters of an inch in diameter.

 

The Classic Work by Tenney L. Davis, The Chemistry of Powder

and Explosives has a section describing the process of how

they were made back in the day.  The book is still available and

is one that all aspiring pyrotechnicians, in my opinion, should

possess.

 

It is true that this sort of knowledge is becoming more and more

controlled by our society.  Public discussion is often frowned upon

as the topic nowadays is considered "dangerous" or "far right wing

extremist" in nature.  Times have changed.

 

They weren't available in Iowa where I grew up, but we could easily

get them by ordering by mail from Banner Fireworks Company in

Dayton, Ohio, or Rich Brothers Fireworks in Sioux Falls, South Dakota,

for freight delivery in Iowa; or we could drive down to Missouri where

they could be purchased an any fireworks stand.  Fireworks were

legal in Missouri but illegal in Iowa.  Even so, we in Iowa had no real

difficulty in getting anything we wanted.

 

Correction:  Banner Fireworks was in Toledo, Ohio.

 

 

The Chinese made "snappers" which are tiny pieces of gravel wrapped

in paper and twisted closed are a different composition, usually a tiny

pinch of Silver Fulminate in with the pieces of gravel.  Very tiny.

happy for the post to be moved accordingly, but technically the items are pyrotechnic.

 

also some stuff in davis is not totally accurate, and the sensitivity of some mixtures does not seem to be born out in practice.

 

commercial process for current manufacture by the Chinese are not documented, and for completeness this would be useful to add to the knowledge base, if any one knows.

 

your post was unnecessarily aggressive in nature and unwarranted, please modify your responses in fututre

i already have the john donner's book, but the other references i will peruse at my leasure

thank you

[Piccaso]

Thanks for the info. I wish people here could be more welcoming to posters and not try and attack and scold all posters.

[WRAITH]

Potassium chlorate & Sulfur or..
Potassium chlorate & Red Phosphorus (the shavings off a box of safety matches work) & is reasonably shock sensitive. What your after is silver fulminate, very scary stuff.

Sea monkey your awesome!!  I asked a few weeks ago for books and only one guy was nice enough to help out and gave me 2 excellent books. Everyone else yelled at me for piracy and stealing and i was scratching my head thinking"no one buys music or books or movies anymore,what is up with these guys. I quit buying cd's and movies 15 years ago when 56k modems and the piratebay was founded.The link above is much appreciated,i have about half but the rest of these books i wanted badly,awesome link!!!!!!

This is why people don't share. A simple thank you to the guy, without billboarding the very thing that draws negative attention, would have been suffice.

You clearly have no appreciation that this forum, and every other fireworking and rocketry and energetic substances forum, are actively monitored by a variety of alphabet agencies. Or that some of your less-than-wise posts suggesting illegal or dangerous activity are probably flagged and logged for future reference. Anything on the internet is permanent. As in permanent evidence. Against you. Or that tracking individuals with questionable motives is a simple button-clicking task, whether a VPN/Tor used or not, to track you back to your front door. And they could use the silliest pretense of tracking your pirating habits and illegally downloading pyro texts to gain warrant access to poke around further. No question Ron, you've been flagged. Now they're just waiting to see precisely how stupid or dangerous you might be. So continue to help them build a case against you. Might just find yourself back in the courtroom again sometime in the future for preventable stupid shit. This is probably one of the first stops some idiot with nefarious intentions will lurk and scour for pyrotechnic information. Impact explosives? Sure you can find the info. Useful info for fusing destructive devices. HE synthesis? Well, your chem knowledge is even below most of the inexperienced TATP bombers in Europe, including the several that accidentally blew their own asses up, but please realize that your claims do not go unseen or unnoticed by LEOs. Even if your statements don't rise to the level of federal attention/concern, don't think for a second that this information, if worrisome in the least, won't be shared with local LE in your state/town who I'm sure would be happy to find the time to investigate a little further.

 

You should be neither annoyed nor laughing, but instead taking this shit a little more seriously.

 

Not to mention the black eye some of your claims and poorly-considered statements give to the responsible fireworking community.

i would like to re visit this topic,

so how would you coat coarse gravel with an armstrongs type mix ??

 

see attached pic.

 

because the( presumably) chinese are making these adult throw downs by the thousands

 

it must be a simple process done by cheap labour i am guesssing ?

 

coated wet and allowed to dry in tube ?

 

there was no loose powder it was all coated on the gravel.

coated gravel weighed about 0.88g so the actual weight of composition would be quite small.

 

choice of glue?

 

would appreciate any useful comments, since no book seems to have documented the process, maybe the closest is shimizue with cracker balls 9using chlorate /realgar).

it would be a shame to loose this knowledge if only for posterity

Honestly, I have no interest in something this sensitive. OTOH..I bought a case of them and use the “guts” with a perc/mag comp and paper soda straws. But I’d never wanna make it. Let the Chinee do this work.

[dave321]

just found this on youtube,

 

difficult to say if this is authentic or fake, but knowing the sensitivity involved probably accurate

beware the warning
