Iceland Posted December 30, 2019 Posted December 30, 2019 I have had some potassium perchlorate for years at least from 2011 it is.. and it seems it lost its potency.. I was wondering if putting it in a stone pounder normally used for herbs.. would the potency come back? or otherwise ball mill it? or should I buy new potassium perchlorate. I asked an expert chemist but he is not into pyrotechnics so he could not answer my question.. back in 2011 this stuff was super potent
Elisabeth Posted January 22, 2020 Posted January 22, 2020 (edited) Blade milling will help, but to fully restore potency, blend in 0.5% finely crushed sildenafil citrate. Not only should it restore potency, but it should make your perchlorate fuller and longer lasting. Edited January 22, 2020 by Elisabeth 1

Its just clumped a bit and not as fine as it was beforehand. Edited January 24, 2020 by PTFE
davidh Posted January 24, 2020 Posted January 24, 2020 Exactly how does a molecule lose "potency"? It would have to react with something in the surrounding environment and change into a different molecule. This happens to aluminum, magnesium, magnalium, red phosphorus, charcoal, iron/steel, and others, but none of the common oxidizers (as far as I know) .
SharkWhisperer Posted January 28, 2020 Posted January 28, 2020 (edited) Well, my Pot Perch seemed to have lost "potency", too. Drawing on my vast knowledge of pyro chemistry, I arrived at the conclusion that my perc had, over the course of several weeks of neglect (I ignored it while I was making BP stuff), degenerated into the typically harmless salt substitute KCl. Genius, right? I know. So I acted accordingly, lest it go to waste, and promptly added it to all of my kitchen salt shakers. You know...KCl and hypertension control vs NaCl. But I was very surprised when I was grilling some heavily "salted" ribeye steaks a few months back, and they immediately burst into flames and shot approximately 4 feet (a little over a meter, Euro People) straight up off the grill, did a perfect flip, landed back on the grill on the opposite side, sizzled for a little while, and then blew up again just like the first time. I was stunned any mystified. But no more explosions and after 6 more minutes I had the tastiest steak ever known to man! The seasoning seemed a little off, though, but it was still super yummy! Now it's been a few months later and I have developed this huge goiter, which I'm sure is unrelated to anything pyro. I mean, of course perc hinders iodine uptake at the thyroid gland, but I stay safe with that stuff, and stick with KCl in the kitchen. So, although anecdotal, this serves as an example of how KClO4 can indeed degrade to a very useful kitchen seasoning! Disclaimer: <<Newbies. This is sarcasm. KClO4 does not degrade without the assistance of a blowtorch. It is mildly toxic. Do not eat it, ever, please. >> Edited January 28, 2020 by SharkWhisperer
Pyro55 Posted March 8, 2020 Posted March 8, 2020 (edited) I still have a pound of dark Al from Star Lake Enterprises*. It is as good as new. I store my AL in large ammo cans with desiccant. I store my oxidizers like this too. They last forever. *Anyone remember Star Lake Enterprises? Edited March 8, 2020 by Pyro55
Jimjimboom Posted April 13, 2020 Posted April 13, 2020 Can someone tell me is this an australian pyro forum?
Mumbles Posted April 13, 2020 Posted April 13, 2020 It is based in the US, but we have members from so over the globe. There's a decent contingent from Australia.
cevmarauder Posted April 13, 2020 Posted April 13, 2020 It's possible that it's absorbed moisture; mine did when the dehumidifier in the bomb shelter bit it during a muggy June. It's got a very low solubility, but it's not insoluble, 9 years is probably enough time to absorb at least a little moisture. You could try drying it in a drying box. And echoing what others said, mill it to get finer particles before drying. Hey Mumbles, sent you a PM a while back. I'm sure your inbox is worse than my work inbox, though.
