I would be very cautious when it comes to dismantling devices. If you want to experiment with colour, order some perchlorate from Skylighter and items such as strontium can be obtained from pottery suppliers. I know you said before you don?t like paying the shipping charges etc but you need to weigh up the costs against safety. Even if you order 1kg of perc, it will keep you going whilst you find a supplier more local to where you stay.

i was thinking about ordering perclorate from pyrohobby.com. a pound is only like $8 and i could get like 2 or 3. i could also get a pound of barium carbonate, iron oxide red, red gum, strontium carbonate, and parlon. but the dont have pvc . what is the solvent for parlon again? acetone, mek?
btw i have heard that when u order knives, chemicals, etc on the net they put u on a government watch list in the US. does any one now this is true. i dont like the idea of being spied (watched) upon all the time it gives me the creeps.

It is true that the new Homeland Security crap puts you on a list when you order certain chemicals that could be used in es, but as long as you don't actually go around blowing up people or other things, you'll be fine.

"Pottery" is items like cups (φλυτζάνια) and bowls (κύπελλα) which are made from clay (άργιλος).
A pottery supplier will sell things like clay (άργιλος), kilns (κλίβανοι), tools (εργαλεία), and materials to make glaze (λούστρο) to people who wish to make their own pottery. Glaze is sometimes made from chemicals like copper oxide (οξείδιο χαλκού), barium carbonate (ανθρακικό άλας βάριου) and strontium carbonate (ανθρακικό άλας στροντίου) which are used in fireworks to make coloured flames.

So My 2 Cents worth would be in line the the Djinn, Whats the Point of taking these things apart if the tresure inside is fools gold. as to dismantaling, the Primer/Striker Comp on the Top contains red Phosphorous, so the if you insist on this venture, use a hack saw and gently cut about 2"s off of the business end, that should clear the prime.
Mods: I would not recommend this, But I wanted to steer him Clear of the Prime, which I believe is the only real Danger involved here. The Comp itself will not Deflagrate, ignite, even spark when sawn in half.
That being said, I agree with the "Thats Cheating" statement someone made earlier also, There so Many Beautiful Reds Out there Why would you waste your time then take credit for "look what someone else did" Even if you modded it.
Since I have been gone for awhile I am just Catching up, seems like alot of posts regarding taking things apart, in general a bad idea as the Chinese and other production countries don't gerally give you an instruction sheet, formula list or construction details with each device, all of which would be needed to safely carry out some of these"Let see whats inside" posts/ideas.
Yes it can be Done, Heck I've done it.....A LONG time Ago. Allow me to reverse engineer a NIKE commercial Saying...."Just DON'T Do It".

Reading through rec.pyrotechnics I read an comment by Mike Swisher. He said that you can substitute the KClO3 in some formulas directly with KClO4. At least in those formulas with a somewhat lowder KClO3 content.
I really got no very convincing red star with a deep colour. Not with blesers KP or with shimizus formulas. Not at the ground, not in the air.
So I came across a Lancaster red:
Red Gum 13%
As I don?t like chlorate very much and don?t evenb have any I subst. it with an somewhat smaller ammount of KClO4 to balance the oxygen a bit. I used 60% instead.
I was amazed. This is a really deep, red colour with a somewhat light red tip. The color simply satisfies me and the formula works without every PVC or other clorine donor.
Please try it! I try to take a photo of that red today if it gets darker!
My first very own firework pictures are online!!!
