ok thanks for all that, il be sure to make my own jar or use the plastic one. yer what the hell is that envalope?been wondering about that for ages. should i use one set of milling media for milling chlorate... and one set of milling media for BP then?

[bernie]

Yes. One batch of media for KCLO3. All by itself. Another set for BP. Keep them labeled.

[Pyromaster2003]

ok then, cheers.

[Pyromaster2003]

what chems have you found you can buy from looking in the yellow pages?and have you had any trouble in purchasing?

[smpip]

The list is long, but I think its more to do with were I am, (industrial, rural areas as opposed to City areas), the other thing is having existing business accounts, and also that thing that one hopes comes with age, Wisdom.

[Pyromaster2003]

yes i think it must be. iv looked in my yellow pages and havnt found a damb thing. where about do you live?

[adamw]

I don't think there is a 'Pyro chemical' section. Laboratory supplies / Industrial etc is where you want to be looking.

About the topic of milling media being porous and absorbing chlorate, then used for milling BP and the BP spontaneously ignites while loading a finale for example.

Just ordered my ball mill two days ago(same dual ball mill from UN just 1/4 cost and without the UN stickers). First project will be BP, then comes rolled stars in a rolling machine, mines, quickmatch, etc.

Now some stars require chlorates be used. Is there a specific way to clean my media to rid it of any possible contaminants of other chemicals? I will be purchasing a set of Lead/Antimony media and two sets of ceramic media. Lead/Antimony for BP and ceramic for individual chemicals (one set in each drum of the mill). I wont only be milling one chemical with each set so I would just like to know the best way, which liquid, disposing of the liquid safely, etc. would be safest, cleanest, etc.

Thanks!

Go for it Bernie, Your the Man when it comes to The Individual Media per Chem, in those nicely labled Jars

What should i buy as my first chems? and what quantities?

[broadsword]

Assuming u want to make pyro things then i would have said, Potassium Nitrate, Sulphur and Lumpwood Charcoal! At a guess!

[Yugen-biki]

Ha ha ha! Yes...
But some perc, red gum , atomized Al and some "colour salts" ( SrCO3, Cu(III)O ) is a good start.

With it you can make some stars, bursts and Lift (BP) Used for rockets or shells, and drivers.

[broadsword]

Perchlorate, where we meant to buy that? I thought it was REALLY hard to find?

Hope this is the most appropriate thread

Just a quick post to let you all know about a source of Strontium Sulphate. Celestite is Strontium Sulphate in crystal form. It is very brittle, and can be crushed into a useable powder easily in a pestle and mortar. Processing shiny blue crystals into pyrotechnic ingredients is very rewarding

It is easily available from various sources (think gem/fossil shops) and is cheap. I paid two quid for a chunk of roughly 100g.

Now, I've only ever seen AP strobe formulas using the stuff, but a simple 3 part formula with sugar, oxidiser, and the Celestite produced a most wonderful colour.

It's like a pinky red on it's way to purple. Nothing like Strontium Carbonate or Nitrate formulas I've seen. I think this chemical has superb potential for producing vivid reds and purples. Just got some experimental tweaking to do now

sorry for posting this but does anybody know any online pottery shops which sell chemicals because i have typed in pottery supplies ect on google and nothing useful came up, and i want to try pottery shops because i have read in previous post's that you can get for eg. 1KG of CuO for a few pounds
