I think in that case You must make the same "tricks" like with iron meteorites. Using oil +heating or try to put it into red devil solution to remove all acids that can start rusting. Ghubara must fall in very "bad" place, thats why he is now heavy ruster. -----[ MARCIN CIMALA ]-----[ I.M.C.A.#3667 ]----- I am sorry but I have to disagree with both of you. Ghubara is not a ruster. In fact it is quite stable. Look at this one: _http://www.impactika.com/catpix/AB145.jpg_ (http://www.impactika.com/catpix/AB145.jpg) I have had it a couple years, it is in a Riker mount, no special care at all. And it is just fine. And I have a few other slices of Ghubara, all are in Rikers, and there is no rust on anyone of them. In fact, I think that Ghubara is a very pretty, very interesting meteorite, and greatly under-rated. But then I like those dark meteorites, they look like thousands of stars in a dark night sky.
