A little light light....

I'm not really sure what the quote is saying? It seems to be trying to give the impression that it is safe but I use it a couple of times a year to show either it's lovely white light when burning or to be used as a burning fuse in the thermite reaction... ! I also drop some in acid to show hydrogen being evolved...so keep it away from your can of coke or you might end up with no torch left! Maybe it is much safer and less flammable as solid block rather than in thin strips.
Enjoy... And regardless of its properties, it looks brill. I must admit, having only ever handled small strips of it, I never appreciated that it was so light weight!!!

From good old wiki...
Magnesium is a highly flammable metal, but while it is easy to ignite when powdered or shaved into thin strips, it is difficult to ignite in mass or bulk
..so there you go!

Not that it helps the discussion much, but I believe that the superstructure of HMS Sheffield was a aluminium-magnesium alloy, which may have contributed to her swift destruction in the Falklands conflict following an Exocet strike.
Chris, do they still demonstrate the thermite reaction in schools? It made a lasting impression on me 50 years ago - the usual spectacular flame from the magnesium fuse, and then great balls of fire - well, molten iron - rolling across the protective metal sheet on the teachers bench.

We used to make parts out of 2 1/2" diameter bar, still got some bars left, probably about 5 or 6 metres.
Problem with magnesium is that although it turns nice and you get a shiny finish it starts to oxidise and get a white flaky appearance very quickly unless anodised.
Best use for the turning is to rub them between your hands with a pair of rigger gloves on to turn it into small chipping, perfectly safe doing this.
Then throw the chippings over someone's shoulder whose welding.
Awesome, definitely a brown underpants day :lol:

You're bl**dy cruel you are John :hammer: It's no wonder it's tropical in your workshop. :lol:
Cheers Dek.
