As for staining and residue I see non. However, I did weigh the meteorite and before I did this process it weighed 3.48g and now it weighs 3.43g. So if you have a small fragment this process could make your 1g rare meteorite a 1 gram lesser meteorite and take it out of the 1 gram and over bracket. But for what I did, the results are fantastic and losing 50mg of the meteorite was worth it, and I think the 50mg was the rust, so it was a win win situation.

Stone meteorites are more porous and absorbent than irons. Have you noticed any residual smells, staining, or residue?

The meteorite looks so much better. I can see the true color of the meteorite, I can see the texture and the gray matrix. I have a link down below of before and after images of the meteorite :) Take a look and you will be amazed of the results. > > http://www.flickr.com/photos/48262799 at N03/4985819064/sizes/l/in/photostream/ > > Shawn Alan > IMCA 1633 > eBaystore > http://shop.ebay.com/photophlow/m.html?_nkw=&_armrs=1&_from=&_ipg=&_trksid=p4340 > > > [meteorite-list] Rust Question about my stone meteorite. > Jimski47 at aol.com Jimski47 at aol.com > Sat Sep 11 07:38:57 EDT 2010 > > Previous message: [meteorite-list] Tunkuska Tektites? > Next message: [meteorite-list] Rocks from Space Picture of the Day - September 11, 2010 > Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] > > -------------------------------------------------------------------------------- > Hi Shawn, > > I doubt that soaking a meteorite in alcohol will remove rust.
