hmm, my 3kg nantan that I cut using water cooling is stay also on near my Dronino endpiece and without any protection its stable like hell. Another endpiece also. Slices from this specimens I have from, I dont know, maybe a year here and no rust. I'm also surprized about my nantans, becouse I see too many rusting nantans and other meteorites, -----[ MARCIN CIMALA ]-----[ I.M.C.A.#3667 ]----- http://www.Meteoryt.net [EMAIL PROTECTED] http://www.PolandMET.com [EMAIL PROTECTED] http://www.Gao-Guenie.com GSM +48(607)535 195 --------[ Member of: Polish Meteoritical Society ]-------- ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list
