I would just like to add one comment to Sally Shelton's excellent advice to the query on the stabilization of a rusting meteorite in a personal collection. If you've been handling the specimen with bare hands? Stop! The chloride salts and acids found in human persperation can etch fingerprints into almost any metal surface. As a metals conservator, when I find an object without such fingerprint corrosion it is definitely the exception. Please wear clean white cotton gloves or vinyl (make sure that there is no gloving powder to get on the object) when handling your collection. Cheers!
