    Wow,
    This is cool, a group of people who think like I do, safe is better, thinking ahead is good. Glad I could ask a question that inspired a new forum that was needed. Ron

    Don't ignit magnesium! If you haven't already anyway. It will not be put out by any means other than the exhaustion of fuel. Sand only makes it a little less dangerous. There is a chemical that you can buy from the pharmacy, you put a couple of drops on the material and if it turns grey it is mag. I'll try to find the info on it if anyone is still interest...still has any skin.
    Stop talking about it and do it already!!!!!

    Hobbiest,
    That would be good information to know. If you remember what chemical it is please post it. Thanks Ron

    found info!

    Here is the info for telling whether aly or mag. Magnesium is distinguished from aluminum by the use of a silver nitrate solution. The solution does not react with aluminum, but leaves a black deposit of silver on magnesium. Magnesium is produced in large quantities from sea water. It has excellent machinability, but special care must be used when machining because of its low kindling point. Knew I'd find it sooner or later!

    Archimedes law

    Find the volume of the part by putting it in a cylindrical waterbucket. Measure waterlevel before and after the part is in. The difference is the volume. Then weigh the part. You can now find the density. Al is 2.7kg/liter and Mg is 1.6kg/liter. Safe and simple.

    Best regards

    John

    Too many pieces to that puzzle though. Silver nitrate is easier, and just as safe.
    Stop talking about it and do it already!!!!!
