[meteorite-list] Possible new Illinois meteorite

[Joe Kerchner]

I tried the allertest on a few known chondrites and they did not show positive, maybe the allertest I have is bunk. I tried it on a few H chondrites and it not once tested positive. I have had it for a long time, maybe it is too old, I'm not sure, but it didnt work. I'll have to order some more and try it again..
Best,
Joe K

Joe,
If you read about allertest on Randy's site you will see that it is a very sensitive test and will detect even trace amounts of nickel. I have had the same results. Fe Ni will test positive evey time. Having said that , there is magnetite on Mars right? 
Good luck. Carl

Al Metterling is running a few tests on it and sending a couple sample to a friend of his for further testing.

This is just a feel good test but if it is malleable that is a good sign. I hope it is. I am very excited for you. This kind of thing inspires all of us. Carl
