Short5 Posted April 12, 2012 Posted April 12, 2012 Alan's site is down, hope all is okay. He had a formula for a mix that ignited when struck on a match box. Does anyone know what it was? from memory it was Potassium chlorate, antimony trisulfide, and air float charcoal in a NC slurry. I don't remember the amounts or if that was all that was in it although I think so. Any help appreciated.
Sabdacrab Posted April 12, 2012 Posted April 12, 2012 Hey mate,I don't have Yates' formulae, but here is a link to thegreenman's website. http://www.thegreenm.../pfp/other.htmlThat page details 4 scratch igniter comps, and a heap of other great stuff.Hope this helps! Cheers, Seb.
Short5 Posted April 12, 2012 Author Posted April 12, 2012 Thanks for the link but I am looking for Yate's mix in particular.
Mumbles Posted April 12, 2012 Posted April 12, 2012 It's 7:3:1 Potassium Chlorate:Charcoal:Antimony Trisulfide. http://web.archive.org/web/20090119194209/http://vk2zay.net/composition/52
oldguy Posted April 13, 2012 Posted April 13, 2012 Not sure if this will help you, but here it is: Composition of Commercial Safety Matches and Strikers Component % Match animal (hide) glue 9-11starch 2-3sulfur 3-5potassium chlorate 45-55neutralizer (ZnO, CaCO3) 3diatomaceous earth 5-6other siliceous fillers (powdered glass, "fine" silica) 15-32burning-rate catalyst (K2Cr2O7 or PbS2O3) to suitwater-soluble dye to suit Strikers animal glue or casein 16red phosphorus 50calcium carbonate 5powdered glass 25carbon black 4
Short5 Posted April 13, 2012 Author Posted April 13, 2012 (edited) It's 7:3:1 Potassium Chlorate:Charcoal:Antimony Trisulfide. http://web.archive.o.../composition/52Thank you Mumbles. I see you pulled it up through some sort of archive. Any idea what is up with his site? What I like about this mix is it contains no sulfur and must be scratched on a match striker like a safety match. It seems relatively safe to me. Edited April 13, 2012 by Short5

I like to make smokes and have made pull igniters with matches as shown in a tutorial on here but had an idea for a simpler device using the mixture quoted rather than match heads.
oldguy Posted April 13, 2012 Posted April 13, 2012 This might also interest you. Friction striker paint for roller applicator: Red phosphorus 50 – 70 % Poly(vinyl/acetate) 10 – 20 % (as dry solids) Inert fillers 10 – 40 % Getting RP is a GIANT regulatory PITA. But, if you can acquire it. RP in a PVA solution painted right over the top of little short Emory cloth strips make a fine striker.
Short5 Posted April 13, 2012 Author Posted April 13, 2012 Well it works. It is a bit more sensitive than a match on the striker and will light visco when painted on the outside of it.
mabuse00 Posted April 13, 2012 Posted April 13, 2012 Antimony Trisulfide is optional, but makes it a bit more sensitive. It can be left out, perhaps giving a somewhat safer and cheaper mixture at the expense of having to strike harder or a few times to get reliable ignition. I've never saw a formula without sulphur or antimonsulfide - any experience how good it works on commercial matchboxes surface?
