[meteorite-list] Reverse Electrolysis [was: List of known Rusters?

[Greg Hupe]

Hello Concerned Iron Owners,

Has anyone tried 'Reverse Electrolysis' on an iron or pallasite? I  
conserved a batch on shipwreck cannon balls that had been in the ocean  
for over 200 years. I ran them for two years then brushed 'Ospho' on  
them and then flat black paint, not a speck of rust one year after  
treatment conclusion. Obviously we wouldn't want to use the Ospho or  
paint but think I will try one of my complete Mounionalusta stones and  
see what results I get after a year of Reverse Electrolysis. If  
someone has tried this method, please let me know... It will be  
interesting to see if it works since it will be submersed in fresh  
water with an electrolite to draw any rust-causing minerals out of the  
metal.

Best Regards,
Greg Hupe
