Someone at the PGI convention this August was shooting large straight
fire magnesium aerial salutes. From the sound and shock wave they must
have been three to five pounds and the flash was so brilliant that they
caused ones eyes to ache for a moment. They may have been magnalium but
they looked like magnesium/perchlorate or magnesium /potassium nitrate
to me. Many years ago as a kid I thought all flash powder was
magnesium based and that's what I used. It is noticeably brighter than
4-1-1 black aluminum flash in a side by side comparison. Not knowing
any better, I used to make a 2-1-1 mixture of 200 mesh magnesium,
potassium nitrate and sulfur. In time this will start "cooking"
especially in humid climates and can heat liberating hydrogen sufide.
Don't make it. I once retrieved a large dud magnesium, KNO3, Sulfur
aerial salute that had been floating overnight in a lake. The thing
reeked with the familiar rotten egg odor and the heavy, soaked
cardboard casing felt WARM. I should have stayed away from it but I
re-fused it and lit it on the ground. It went off as normal but I
learned a few things about magnesium. It's not aluminum.
