Mg on Sparklers
I've recently chipped the Mg of a pack of sparklers and crushed it up into a fine powder. After i'd done this, i mixed it with KClO3+Sugar mix. I lit
the mixture however it was very slow burning and nothing like what i'd expected from flashpowder. At first i though it was due to the Mg off the
sparklers and this is still my theory now, however i was wondering if anyone could give me any ideas as to why the reaction is so 'boring' and what i
could do to improve it or any suggestions as to how i could 'refine' my Mg powder.
Thanks

Sparklers are typically Fe based, not Mg. Iron has yellower, more interesting (forked) and safer (cooler, less reactive) sparks than Mg or Al.
Further, it is relatively coarse and not likely to explode in any preparation. Third, sparklers are a composition, not powdered metal! I don't know
why you would expect to "chip Mg of [sic] a pack of sparklers" in the first place. And finally, KClO3 tends not to explode with metals -- I don't
know why. I've never had KClO3 burn with the finest magnalium I have prepared (probably circa 200 mesh).
Besides that, the sparklers may contain sulfur (I don't know...all the more reason) which is a BIG naughty no-no around any chlorate.

Magnesium
Under U.S. Federal law, magnesium isn't allowed in consumer fireworks.
Magnalium is permitted however. As for flash using chlorates, get the mesh
size up to 600+ and you'll notice a difference in how it performs.
