Edit: Which part of the pencil sharpener is made of magnallium? The spiraled blade thing?
Edit 2: Heres a good non-antimony glitter.

What did you prime your crackle with? What method did you use, cut , roll and to what size?

i thought it was a 90:10 mgal alloy?On the metal sharpners, the big chunk of metal that the blade is screwed to.

Not sure what a sensible offer for the 4Kg lumps would be, but if anyone gets one, let me know.
I believe they also sell Mg/Al scrap in various grades, but you will need to contact them for that. They actually sell pyro powdered Mg/Al but only in quantities of about 50Kg

i have made small fountains using MgAl from pencil sharpeners. It makes a nice, bright effect - more like Mg than Al.

I haven't actually used pencil sharpeners, I found a much more plentiful supply.
Motorcycle cylinder heads and engine casings are often magnalium. Ranging from 2-10% Magnesium (I checked this on casting materials company websites).
It burns well and bright white, I guess the magnesium colour intensity drowns out the aluminium.
Go for the parts of the casings which corrode fastest.
I have no easy way to process it (my hands are sore and my file is blunt ).
Anyone know an easier way of producing small granules? (you can have some)
I will try old brake calipers next.

Yes indeed, but I fear it will only really work on the brittle MgAl (50/50?).
