I happen to have a lot of MgAl, and not much use for it as I don't make dragon eggs anymore. I was thinking of using it for Glitter.

 

Is there anything in particular I should know about using MgAl? Does it behave the same as Al when it comes to the water-nitrate reaction?

 

Besides substituting it directly in formulas like D1 and N1... W19 looks like a good comp to try out.

Although I usually add coarse MgAl in small amounts to many AL glitter formulas, I'd suggest trying a glitter formulated for it, like W20. It behaves much different than AL and has a slightly different fuel value. You won't be disappointed.

What mesh size MgAl do you have?

I have -325, -200, and some other size.

 

The -325 stuff is like almost stuck together after a few years... Has to be scraped hard with a plastic spoon to get it back to powder. Odd. :/

USA, not at all 'odd'.  ANY humidity at all will cause Mg/Al to agglomerate.  Your best bet (because it also partly decomposes when that happens) is to have enough to meet current needs, and not store it for long periods of time.

W19 is a nice one. I use 100-200 mesh granular mgnal in it. Nice bright flashes. Don't over wet them, and I found they do best rolled.
