Hey, I just had a brainstorm. I don't have any of the weights handy,
but someone who does should try one of those hardware store lead tests
on them. You know, you have the little tube with the swab and it
changes color if lead is present. Someone try it and let us know what
happens, we're all ears! Allison

Magnesium/zinc? This stuff seems awful heavy to be a magnesium zinc
alloy,
at least the ones I have. I won't use it. Color me skeptical and over
cautious.
