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.
