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.

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.

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
