Strike anywhere matches from safety matches
Few mounts ago I have made some strike anywhere matches from safety matches - NaClO3 + P (red) and little water. I can ignite it anywhere (glass,
wood, paper, skin), but they are not safe. Falling from 10 sm on glass cause ignition. 0,005g composition per one match.

I think that`s IT.
(s)he`s sharing this "Idea" with us.

That "Idea" is not so bad. Natrium chlorate is better than KClO3, but matches must be in a dry and cool place. They are too sensitive to be really
useful, but I like it.

You might try using perchlorate instead of chlorate, it will probably be a lot safer as perchlorates tend to be much more stable than chlorates.

But then, you don't really get the "strike anywhere" reaction.

The red P, mixed with any usual oxidiser is too sensitive. It's harder, to dissolve KClO3 or KClO4, than NaClO3. NaClO3 contains more O, but is more
hygroscopic.

a little bit safer method would be the one outlined here: http://www.popsci.com/popsci/how20/7308716ca54f8010vgnvcm100...
for the outside coating, you may use NC laquer instead, it also gives them a more water resistant quality.

good point Chemoleo, sorry each.
I don`t have Quicktime player, and so cannot see this. but I must say that lighting a match on your hand is Crazy! esp homemade sorts and with such a
volatile/unpredictable mixture.
in 100, 99 may work fine and them one will hurt you

still, it is not a risk I would wish to take (I have Pain allergies).
IIRC, Phosphorus sesquisulphide is used in the stike anywhere types nowadays, although where you get this or even make this I don`t know.
I`m assuming it`s a little more stable as a compound than the raw RP and Chlorate with binder mixture though.
I`ve had plenty of sucess with home made matches in the past and in different flame colors similar to bengal matches, you may wish to try these also

Alternatively, one could imbue matchsticks with a soluble metalic salt (copper cloride?) for colouring effects.
F. de Lalande and M. Prud'homme showed that a mixture of boric oxide and sodium chloride is decomposed in a stream of dry air or oxygen at a red heat
with the evolution of chlorine.

You will need a chlorine donor + replacement of oxidizer. Sodium Chlorate will dilute any sort of blue/green color from the copper.

Bit of powdered PVC would sort that out though.

Sort out sodium yellow???
That seems unlikely...
Works fine with KClO3 though, the coloring.

I remember one of my friends trying the popsci-article method to make arrow heads. I'm going to assume that since he has all his limbs he hasn't
gotten around to firing them at anything yet...

Hehe, even the smallest presence of Na+ will make pure blue or green impossible indeed. I finally got some ammoniumperchlorate today, for making some
blue light comps, but I was very disappointed to see that it burned with a slight yellow flame in the flame test. (Is this normal?!)
Btw, if you think KClO3 + red P is too sensitive you can also replace half of the red P by sulpher, like is used in toycap compositions. Always use
enough water though, I found that pure KClO3 + red P can explode from friction even with a decent amount of water present! So a "little" water aint
going to do it...

I do the sulpher mix also, the RP has to be in the smallest amounts possible, or put on the outside later as a seperate coating entirely, and even
then you only need to do the very Tip of the match.
I am curious as to a technicality though, does KClO3 and RP mix actualy Detonate, or just burn very quickly?

This has been the subject of considerable discussion in pyro circles for years. May depend on howthe word "detonation" is defined. It definitely
explodes in very small quantities.
In any case this is very hazardous stuff because of its extreme sensitivity. Look up "Armstrong's Mixture" and "Union Torpedoes" in other forums. I
don't have the exact citation at hand, but you might find Charles Nelson's patent from ca 1880 of interest -- see USPTO web site. Many people were
killed and injured manufacturing and transporting these toys way back when.

I am not sure, but i remember reading somewere that adding sulpher to ANY red P mix actually increases sensitivity.

"somewhere"?
Sulfur and red P are used together in many toycap compositions. I tried a couple of them and found that using only a small percentage of red P reduces
sensitivity somewhat. Mixtures of sulfur and chlorate alone need a rather strong hamerblow, whereas using 5:1 sulfur/red P needs something bigger than
a small tap and using red P alone as a fuel will make it very susceptable to even the smallest taps with a spoon...
