Ok, thanks.

I've mailed my chemicals shop 'bout the prices for silver chloride and  
silver nitrate and they put quite the dampener on the idea anyway. While  
it is probably very sparingly used it is still not cheap. Also, the layer  
is probably very, very thin. I guess it would be more economical if one  
would use "junk" silver and convert it into silver chloride with  
electrodes or to silver nitrate with acid. I guess plumbing solder is  
really the most economical way.
