Flash Powder with KNO3

Zyklon-A - 28-11-2013 at 11:16

I have alot of KNO3, and want to make a very fast burning flash powder.
I have Mg powder, Al powder, Sulfer, sugar, fuses, and a scale.
I do not have KClO3/KClO4, the olny oxidiser I have is KNO3.


PS. I don't have much Mg/Al powder.

KNO3 and Magnesium burn very fast, and I dont think you can use it as a fuse. I've tried it before. The ratio of KNO3/Mg could be 1:1 or 3:2. 1:1 will get you a bright sparks, and 3:2 is more powerful.

I suggest you to make very little, few grams, when you try it.

Nitrate salts with aluminum powder is much harder to ignite, and burn much worse than nitrate with magnesium.

I would not have used it as a fuse, as stated earlier I have fuses.
Is it as good as Al+KClO4?

Yes you can try that, I tried it also, aluminum generally tend to react less violent than magnesium. When a metal reaches its boiling point, or near that, it will react, you can see aluminum's boiling point is much higher than magnesium's, which is why magnesium can react easier, however aluminum burns more exothermic.

I don't have KClO4, I just wanted a comparison, I've used Al+KClO4, but ran out of KClO4:mad:, now that I have KNO3, I wanted to know if I can make a flash powder as good as Al+KClO4.

Do they let you shoot off rockets in Dubai? Lol.

As I said KNO3 would make a very nice spark with Magnesium powder, maybe better than KP+Al.

No they don't, I also think I can get deported easily. the laws here are extremely strict

Ha ha, I've been to Dubai, it was awesome, but I'm sure the laws are strict.

I tried it with turnings see this video:

I tried with Al (mixed with other chemicals or not), see here:

Cool videos, thanks.
