Buy some manganese dioxide, potassium nitrate and potassium hydroxide. Fuse all three salts together and dissovle the resulting mass in water. Acidify the solution and collect the potassium permanganate.

 

 

For more info/more detailed procedure utfse......

That's the problem. There is no right way to use it in pyro, period. The compositions made from it are not safe to use, expecially for inexperienced people. They are also overly reactive, and not storage stable.

 

Also, in order to maintain a relatively professional appearance, could you please use full words, such as you, why, and because. People can only gather an opinion of you from what you type, and if you type like an idiot........well you get the picture. It can also cause issues with our non-native english speakers.

if it has nothing to do with pyro then why do i read stuff about it being used in pyro or maybe i'm just stupid but anyway does anyone even know what it does

Q: Why do you read stuff about it ?

A: Because kewlz think it's well... cool.

 

Q: Does anyone even know what it does ?

A: It's an unstable oxidizer. If you know enough to be thinking of playing with it, that's enough to tell you all you need to know about it.

You can buy it anyways, why bother synthesizing it? This stuff is nasty crap, I have plenty but won't touch it because it's such a friggin mess. You and your clothes will be purple for quite some time. Oh yeah, it's unpredictable, which in pyro is something like being handed a lit piece of pyro, you know there is a chance you can properly guage a reasonable amount of time you can hang on to it before throwing it, but screw that you instictively throw it right away not wanting to take a chance on a myriad of unknown variables. Self preservation should trump all else.

I used KMnO4 in flash powder because I can't get somme KClO4:(( but the point is: about 5minutes afther I finsh my flash I heard a big baaaannnngggggggg and my lab blowup. A huge fire afther the bang and my pulse was 160b/min :((( afther accident I decide that I never use KMnO4 for pyro.

 

 

 

P.S. Srry for my english level.

Can someone tell me a company name who schips chemicals in holle Europe??/ pls

Where I am KMnO4 can be purchased at pharmacies.

 

KMnO4 is nasty to handle as it will stain anything a vibrant pink, not to mention that it's also not good to be breathing.

 

KMnO4 is a strong oxidiser, as many of us may have been shown at school when glycerine was added to it.

 

Mixing KMnO4 with an excess of nitrocellulose lacquer produces a gelatinous and rubbery mass, the surfaces of which soon harden, along with the remaining mass.

Once dry it is quite hard, and unlike KMnO4 is not readily soluble in water.

 

I have extruded the gelatinous mass through a large bore syringe to avoid having one solid mass.

I have also simply broken up the gelatinous mass using a sharp edge.

Both of these have to be done quickly, as the rubbery mass very quickly hardens.

 

The resulting hard product ignites very readily and energetically, leaving the tell-tale brownish stain of Mn.

 

Difficult to grind using mortar and pestle, not only because of it's hardness, but it may spontaneously ignite; I've had my small 7cm pestle suddenly erupt with an ~25cm burst of flame, and that was only a small amount of product.

 

To view the following, right click either image, or the link to the burn video.

For some reason I don't know, when left=button clicked nothing happens,

KMnO4 crystals, AFTER excess NCL added, and gelatinous mass dried

KMnO4 crystals, AFTER excess NCL, dried, set aflame.
Note how rapidly it burns. and how hot it remains for some time afterwards.

  • In the image of the KMnO4 after the NCL was applied, there appears to be crystal facets similar to straight KMnO4, yet this product is only rarely soluble in water, unlike straight KMnO4.
  • Straight KMnO4 does not burn by itself so readily.
  • It could be postulated that the KMnO4 merely serves as a holder, or transport, for the NCL, yet the development of the initial gelatinous mass would indicate some form of reaction has occurred, supported by the fact that this product does not readily dissolve in water.
  • The final product may turn out to be useful in e-match mixtures, as the sparks are presumably hot particles of Mn.
    This is something I plan on exploring further.
