Potassium chlorate with metal powders?
Did you try such mixtures?
I think, that Mg or Al are too dangerous to be mixed with KClO3 and ignited. I think that iron powder is much safer.

Download "The Chemistry of Powder and Explosives" out of the forum library and read it. It will answer many of your questions.

You really should use the search engine, the forum's and Google, before starting a new thread. This has all been covered many times. Mixing Al and Mg
with KClO3 was and still is to some extent commonly done, however, KClO4 is more commonly used now in such mixtures. Iron powder and KClO3, never
tried that one, it doesn't sound like much fun though, storage must be difficult.

Al + KClO3 (stoichiom.) is fine and burns very hot. Mg + KClO3 = flash powder.

Storage? I see no need for storage.
Potassium chlorate and iron should be stored separately. Just mixing few grams and igniting would be enough, at least for me.

Yeah, some years back I started mixing varies things in small quantities, lighting these mixtures, hitting them with a hammer, etc, etc and from there
it just grew and grew kind of like some sort of strange disease. It's a great hobby, I like it a lot.

I had a gorgeous (and very old) hard copy of this book which my friend luckily found amidst a bunch of junk at a church rummage sale. I just
recently lost it at a camp site, and I was only 3/4 of the way through reading it. The worst part is that even if I did find it, it was pouring down
rain. I may never be the same. I was sure it would become my bible, as it was certainly becoming very dear to me. Furthermore, as far as I can tell,
Tenney L. Davis is my freakin' hero.
I was also disappointed to see that the copy in the forum library did not contain the foreward about some of Davis' purposes behind writing the
book (besides the class he taught). If I remember it correctly, at one point he states the possible need for young chemists to aid Allied troops by
providing innovations on the WWII battlefront?

The Tenney Davis book, originally written in 2 volumes, WAS intended to teach the vast number of engineers, chemists and pyrotechnists needed for
production during WWII. My hard copy contains a forward indicating this-
I will compare the forum version with my hard copy when business allows. October?!

1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

A couple interesting books on the subject.

With more than a 4 to 1 difference in downloads I think the author should have used 'star-bursts' instead of glitter. Maybe people think the title
suggests glitter the shiny sprinkle kind.
While somewhat old these titles probably should be added to the library if for no other reason than the safety information which seldom gets mentioned
in this area. Knowing not to use flowers of Sulfur for instance. Not knowing that one fact alone caused severe burns to a hand one day in the early
70's as a few items were created for the 4th of July.
