Arw Posted September 2, 2016 Share Posted September 2, 2016 hey guys.as I told you I was trying to make red pillbox star and i done.i think about prime that whit sulfurless primer.for test i use H3 and it dosent work well.when i thinking again i starting playing white them.i just roll 3or4 of them in a bucket and suddenly they starting to burn and fire move to other stars and .......now I'm OK and I know chlorate composition is so danger and unstable even without sulfur.that's my comp.Lancaster's Red Pillbox Star, Page 9264...Potassium Chlorate19...Strontium Carbonate13...Red Gum04...Dextrin my dear shimizu :-( I can to save them I'm ok cause I use my PPE and i never use dmn chlorate composition.

OldMarine Posted September 2, 2016 Share Posted September 2, 2016 Yikes! I'm glad you're alright. Link to comment Share on other sites More sharing options...
MondoMage Posted September 2, 2016 Share Posted September 2, 2016 I'm curious what caused them to ignite. To my (admittedly inexperienced) eye it doesn't look like there was anything in there that should have induced a spontaneous reaction. Unless it was caused by the stars bumping into each other as you were rolling them around for priming. I've heard that chlorate comps are sensitive, but are they that sensitive?

I've heard that chlorate comps are sensitive, but are they that sensitive?Friction!when they ignite they were dry and I'm not rolling them for priming.I'm just playing with them.I think there is no reason but friction.

Adrenaline Posted September 3, 2016 Share Posted September 3, 2016 The composition shouldn't be that sensitive. The only thing that comes to mind is impure strontium carbonate causing the problems. Did you by any chance use strontium carbonate sold in pottery/ceramics stores? It often contains sulfides. This would of course make any chlorate composition very sensitiveto both friction and pressure.An easy way to check for sulfides is adding vinegar to a sample of your strontium carbonate. A smell of rotten eggs would confirm the presence sulfide-impurities. Link to comment Share on other sites More sharing options...

Mumbles Posted September 6, 2016 Share Posted September 6, 2016 Not this sensitive. There is something else at play, or something you're overlooking. Link to comment Share on other sites More sharing options...
