Alright, I have a few questions;

1. Exactly what good is iodine crystals to any plausable pyrotechnic mixture?
I have a lot of them; a friend acquired them (don't know how) and gave them to me, around 20 ounces of them.

2. what good are Iron filings ; could someone give me some compositions that I could use? The mesh is around 80-100.

3.I actually am striving to make my own fuse, AKA not buying fuse any more. Anybody have any good, slow, and reliable formulas that may be good for coating string with for some fuse?

Read the MSDS for iodine crystals. Good stuff, its a must. Sorry too much of a hurry to post link.

P.S If your going to expirement, All I can say is REALLY know what you are doing.

miniskinny,

Regarding points 2 and 3, please make use of the search funtion on the forum. You will find that there are formulas posted with regards to both of these points.

As for iodene, I know it will give you purple smoke, other than that I personaly have not used it for anything else but as pointed out, check the safety msds notes and that goes for any chemicals used in formulas. Always a good idea to understand possible side effects etc.

1. Exactly what good is iodine crystals to any plausable pyrotechnic mixture?

Depends what you mean by Plausable pyrotechnic mixture - I'm pretty sure Iodine is not used in any fireworks. It is used in "water starts a fire" type lab demonstrations, and is the precursor to some nasty compounds.

1- I had wondered if iodine might work as a colour enhancer, being a halogen. However, it isn't used in any firework formulae that I'm aware of, so it probably doesn't, and also because it slowly sublimes and disappears from your firework comp, but reappears all over eveyrthing in the vicinity.

That is how purple iodine smoke is produced - the iodine vapourises then solidifies again in the air. However, if you do this, be extremely careful to keep well out of the smoke, as it is poisonous and will turn you purple.

2- Iron filings are probably the fifth most useful chemical you can have (KNO3, C, S and Dextrin being just before them). Take a look at Flashy's avatar, for example.

3- BP:90, Dextrin:10 is a little slower that the normal 95:5.

Miniskinny, a word of warning. You may find directions for making Ammonium Iodide elesewhere on the web with your iodine crystals, please DO NOT do it. This is a VERY sensitive and unstable explosive that can cause injury or death. This is so sensitive that a fly landing on it or touching it with a feather can cause it to explode violently. It is a nasty mixture best avoided even by the experienced.

To add another word of warning, Ammonium Iodide is also called Nitrogen Triiodide. Watch this to see why you shouldnt really be making it:

Can I suggest you dont use Iodine in pyrotechnic compounds, not unless you want everything stained purple brown. Plus getting iodine vapour in your eyes/lungs is none too wise either.

I have a solution to all problems. Give me the iodine and Iron filings and Ill give you fuse

[miniskinny]

Eh, I'm actually going to get rid of the iodine then...Or better, sell it to someone on Ebay; the prices there for iodine are pretty steep. I have heard of triiodide crystals (bombed the name, sorry), and I have NOT desired to make them, nor do I ever intend to try, unless I'm in need of some fly traps . But I actually was given extra credit in 9th grade science to perform the "water makes fire" experiment in front of my class; though my teacher was rather disturbed, when he later asked me how many differant chemicals I owned. It seems that he didn't really trust me to make fireworks . Anyway...Next time I'll search around before I just mindlessly post; make sure that my topic wasn't already answered.

By the way, I got the mixture of "water makes fire" from unitednuclear.com, NOT the "Negative X" that they have in a step-by-step method, though that is probably a safer method to obtain a chemical composition that ignites by water.

Enough. If you made high explosive - we DON'T want to hear about it here. Enough was mentioned on the subject.

P.S.

This post is referring to someone whose post I have deleted ? not to the last person on this thread.
