Hello, I've been all over google also tried to search "Magnesium Mesh" in your search bar in here.


I used to make flashes that went off really quickly with a mix of KNO3/Mg/S. The magnesium was from Frederiksen.eu, but it was not stated how fine mesh it was.

How fine should my magnesium be for this fast explosion that makes a great flash? I know the mix is highly explosive, and I am taking the right safety measures to stay safe.


Thanks in advance.

Not sure if I should "feed the boomer" or if forum protocol is to ignore these kinds of posts


I think the main concern here is that if you knew enough to make flash safely, you would not ask this question. 


Second, I tend to stay away from powdered magnesium in general, for all compositions. I certainly would never use it in flash - it is considered one of the more dangerous/unpredictable flash mixtures. Especially adding sulfur as a sensitizer - asking for trouble even more. Don't make Mg flash. That's all I have to say on that.

While, I wont say don't make mg based reports. ( its pretty much required for good colored reports ) If you dont know what mesh size to use, you probably also dont really understand the hazards of it. And, really shouldn't be playing with it.
