alternative ignition of thermite

allright im looking for information on a number of different ways to ignite thermite. sure we've all heard of magnesium and yes it's usually third or fourth time is the charm also potassium permanganate which is pretty cool too and the ever popular sparkler of course lots of companies have taken out the magnesium chlorates and perchlorates from these sparklers and are now selling crappy ones without hazmat fees for them so they don't work worth a crap. i read an article from a guy stating he used simple visco fuse to light it even though ive heard it won't work but perhaps it depends on the mesh as in much finer. i use the dark german aluminum about 625 mesh and it will coat any and everything it touches. really though guys let's come up with some ways to lite thermite outside of tradition and share these methods of doing so along with how to obtain materialsin conventional and unorthodox ways because without frst time reliable ignition it's just no fun. also the first fire mix, much like the thermite ignition mix at united nuclear what exactly is it made of and how are some ways the monetarily cahllenged can obtain it and of course the not so challenged.

I'm fairly certain the little striker lighter plug that is cast into the top of a road flare would be enough to ignite it. The thermite grenades have a "first fire" mixture cast on top of the thermite mixture that you are supposed to scrape some of loose before screwing the fuse/initiator spoon back onto them. I think it may be the same or similar mixture to the road flare igniter. If you pull the top plug out carefully all in one piece and shove it into your mixture then sprinkle a little smokeless powder on top of that to insure that it gets started I suspect it would work every time.

I just ignited it with an iodine and aluminum mixture with a drop of water this morning for my science class, it was pretty impressive. Starting a thermite reaction with a drop of water... they thought I was a wizard. ;)

I was using a 2300 degrees Fahrenheit torch to ignite it, but it would only make pretty sparks and burn for 1-2 seconds. I tried magnesium twice and it didn't work. Is it the ignition system or my thermite itself (I've never done this before) that is the problem?

start thermite
lithium metal from energizer battery
potassium persulfate
from http://en.wikipedia.org/wiki/Ammonium_persulfate
then converting it to potassium persulfate shows how

sodium peroxide from burning sodium metal
making sodium metal http://www.youtube.com/watch?v=rL1cKb3_ojE
then burning it to peroxide

theres a lot of videoes on it

potassium permangate

aluminum and copper chloride
aluminum and sulfur
aluminum and iodine
filaments from light bulbs
aluminium and nickel foil electric fuse

my guess is that the thermite ignition mix on united nuclear includes potassium chlorate, red phosphorus, and magnesium. it looks and acts kinda like the stuff me and my friend make. ground up KCl2: matchhead powder, ground up red P: the powder on the side of the match box, and Mg: shaved off of a campgear Mg and flint combination. its VERY hot when it burns, and explodes if its in a container. the first time i made it in a mortar and pestle it blew up and consumed my hand...which is still healing. kinda like flash powder. it was only about a gram, and it got extremely hot. i do not doubt its ability to ignite thermite. i also have heard that a visco fuse works, i just ordered some from pyrocreations.
No. That mix would explode if you looked at it wrong.
i know first hand how touchy that stuff is, but you would want a ratio of 85% Mg to 12% KCl2 to 3% red P. the amount of Mg that you use in this mixture reduces the chances of an accidental explosion happening by making the mixture less sensitive. however it is still friction sensitive, and you would only want to make a very small amount. if you really wanted to ignite thermite this way you would mix up the Mg and KCl2 and right before your ignite the mixture you would gently add the 3% P to it. i would use a secondary fuse to ignite the mixture, probably a homemade KCl2 fuse.
And what exactly is the purpose of the life-threatening phosphorus? I'd expect that much magnesium with nearly any oxidizer to do pretty well...
well what ive noticed about the explosives ive been messing with is that when i added the phosphorus it burned a lot quicker and a lot hotter, i look at it as more of a catalyst. ive tried many times with simply KCl2 and Mg, with no luck. it just didnt burn hot enough. what oxidizer may you be thinking of? ive been wondering if Mg and Fe2O3 would work. it sounds like it would make a low-grade flash bomb
Ah. I see. I wasn't reading carefully enough; you're using improvised ingredients (match heads for chlorate, Red phosphorus from striker surfaces, coarse 'shaved' Mg...) Please, please, PLEASE if you ever come across pure chemicals, do not try any similar mix! The mixture of red phosphorus and chlorate (called "armstrong's Mixture") is infamous for igniting (and/or detonating) at the slightest provocation, frequently removing fingers, hands, eyes, and etc...
