Sodium Persulphate

[ollie1016]

Hello All,

 

The other day I came across this video on YouTube (

) and I wondered if anyone on this forum has any knowlege/experience with it.

My thoughts:

1) Possible use in salute shells

2) use as break for 3" shells?

 

 

Thanks

You can never really trust what you see on youtube. There is so much BS out there. Even if sodium persulfate could provide a oxidizing effect, it would make for a dangerous mix. Im sure they could have used Ti, or other metal laced flash to give the impression it is what they say it is. My advise is to stick with the proven/ safe materials in use for these fireworks. Dont re-invent the wheel of fireworks . Also the Standard 70/30 flash would be much safer than "exotic " flash comps . Your health or life is not worth it.

 

Here is a bit of info. From SM forum: it goes over the uses of sulfates in terms of a oxidizer for flash or comps:

Sodium persulphate is too expensive for practical use. It can oxidise chlorates into perchlorates.

 

It would be interesting to see flash using bromates or iodates. I know that PowerLabs did some experiments with bromates.

I have found 500g on eBay for around £4, in a few weeks time after exams and work I'm going to experiment with some exotic flash powders
