Review (3/5): NOT GOOD FOR TESTING FOR NICKEL IN METEORITES
I bought this kit to test for nickel in meteorites. Most meteorites have 5% to 15% nickel and a positive check for nickel helps to confirm that it is a meteorite. I tested a number of known meteorites and it was not sensitive enough to indicate positive for nickel. The kit does work because I tested it on an actual nickel (coin) but if your purpose is to try to identify a meteorite, it simply isn't sensitive enough to indicate positive for that amount of nickel (5% to 15%).
