I was wondering if there is any compatibility issues with adding
coarse magnesium 'flakes' to a standard 70/30 flash mix to add sparks
in an aerial salute. I know iron and ti is added but was not sure
about Mg.
If it is fairly safe to do does the Mg need to be coated or can a
pinch just be thrown in the mix? I'm weary of flash as it is and just
want to be safe!
Thanks!
