Mike in Co & List, Good question Mike. I have a big ugly Nantan of about 2000 gr. that was covered in concretions and rust. I ended up high pressure sandblasting it and ended up with a very even grey patination. I then struck it with a hammer and it cleaved along natural lines. When I blasted these interior surfaces I got the same dark grey color. Interestingly, the sanding did not remove metal, and flow lines were revealed. Deciding that this abrasive removal was acceptable, I took a 600 gr. rusted Campo and tried stainles steel wire brushing with a hand held Dremel tool. This also resulted in an overall dark grey patination with all of the aerodynamic and melt features still present.
I would ask the List for a discusion on, not only your interst in electrolysis for removing non-meteoric material, but the wire brush technique also, With regards to all, Guido -----Original Message----- >From: Michael Murray <mmur...@montrose.net> >Sent: Sep 27, 2009 9:49 AM >To: Meteorite-list@meteoritecentral.com >Subject: [meteorite-list] question on cleaning irons > >I'd like to try cleaning a small suspect iron so that I can see what >it looks like without all the rust and other buildup.
