To be extra safe, give the drum a rinse with a sulfate solution afterwards. Any remaining barium compounds will be converted into harmless barium sulfate.

I've tried using it as lift, but had to use powder weighing half as much as the shell to gain acceptable height for 1" shells. It seems to be much less pressure sensitive than BP. The stuff becomes quite hygroscopic if oven dried, much less so if it's dried in a pot set in a boiling water bath and stirred frequently. Too much work to make in any case, imho.

I think ordering different types of alu will just make it more clear that you're going for pretty effects and not bangers.

Petroleum spirit works well for dissolving stearine, paraffin and similar, acetone is not nearly as efficient. I suspect it's the same way with stearic acid, but I haven't tested it.
