Scorpion812 Posted June 4, 2017 Share Posted June 4, 2017 Hi guys, i am new here, I have been making pyrotechnics for around a year rught now and just made some aluminium based flash powder and i know that you shouldnt really store it as spontaneous ignition might occur. I alsi made some fountain composition consisting of Kno3CharcoalSulfurAluminiumMealpowder Is this stuff safe to store (i only have 10g)Thanks for your replies in advance!

lloyd Posted June 5, 2017 Share Posted June 5, 2017 Scorpion,That nitrate-based flash powder is subject to decomposition if it accumulates moisture, but it's not terribly reactive. Just keep it VERY dry. Unless it actually gets 'damp', about the only bad thing that will happen is that it will lose its potency. But that's hardly 'flash powder' by modern terms. Even if 10g of it were to spontaneously ignite, it would do little damage, unless it started a fire! It certainly would NOT 'explosively damage' anything. In fact, I doubt that it will even 'explosively damage' a contained 'salute' made of that material. <grin> I imagine you must live in a place where potassium perchlorate is unavailable. The most common 'flash' these days is 7:3 KClO4/Aluminum. Lloyd Link to comment Share on other sites More sharing options...
Scorpion812 Posted June 5, 2017 Author Share Posted June 5, 2017 Thanks for your reply! I will store my flsh and fountain powder in a vacuum container. Yes i sadly live in an area where you can't get potassium perchlorate, but i am planning on making some from potassium chloride Link to comment Share on other sites More sharing options...
