As a newbie, both to this list and meteorites, I want to thank everyone. Im on several lists but this one is the most easy-going one. You people have a great community here!
I feel compelled to share my recent involvement into meteorites. I have been a metallurgist for one of the largest defense contractors in the US for almost 10 years. I have two hobbies; high power rockets and astronomy. I build 100-pound rockets that go well over 2 miles high, and have built an award-winning 20 f5 telescope. (Are you seeing a theme here?) It was only recently that I realized how blatantly obvious it should have been for me to collect meteorites. (particularly iron meteorites!) So, I bought a Nantan and a Compo meteorite to play with. I have a full metallurgical laboratory at my disposal with everything a meteorite lover could ever dream of. from sectioning equipment, to grinding/polishing equipment, to digital microscopes with bright field/darkfield, polarizers and differential interference contrast prisms. Ive been surfing the web for various etchants but am not having much luck. Ive cut a few sections and etched them using my own etchants used for Fe-Ni alloys, even ones with picric acid and hydrofluoric acid. I just cant get as much contrast as I see pictured on websites. Can some of you help me with some various etching techniques?
