We are struggling a bit with electrolysis of some massive cast iron  
pieces and would really appreciate an opportunity to discuss with an  
expert.  While I know that there are lots of labs doing this work, I  
am not personally familiar with any of the technicians.  Any  
suggestions would be gratefully received.
