Molten magnesium in a air atmosphere is quite exciting to say the least,
the alloy you desire requires smelting the two metals in a oxygen free
enviroment, a bbq will not meet these requirements. I suggest you purchase
the alloy ready made from a metals supplier, far to dangerous to attempt
to cook up some at home without the proper equiptment.


The metals will be contained in a cast iron pot with a heavy lid, I suspect
that only a limited amount of oxygen is going to get in, and even then an
oxidised layer on the top of the melt should stop any further oxidation. My
theory anyway! I've read of pyrotechnists trying this without incident, so
my main concern is generating the heat to melt the metals sufficiently.

Obviously I will be taking precautions just in case something happens, I'm
well aware of the reactive nature of magnesium and aluminium, afterall this
is why we use them in fireworks :-)


On your head be it ...

I have sucessfully melted aluminium on a ceramic electric kitchen cooker hob
in a stainless steel cooking pan with a glass lid. IIRC magnesium has a
similar mp.

I'm in the UK though, and we have proper electricity (240V) here.
