<p>[QUOTE=&quot;SuperDave, post: 101812, member: 1892&quot;]My understanding of the process is still imperfect. It seems to me that the top few molecules of silver on a toned coin are something other than silver, i.e. silver sulfide. Unlike dipping, which chemically removes these few molecules forever, the electrochemical reaction described here removes only the &quot;sulfide&quot; part of the toning, by attracting the sulfur which combined with the silver to another substance which likes sulfur better than silver does. No silver is removed during the process - it&#039;s merely freed of the sulfur monkey on its&#039; back.</p><p><br /></p><p>Under strict definitions of the term &quot;cleaned,&quot; it&#039;s cleaning, because a process which changes the appearance of the coin has taken place. After the cleaning, though, no silver has left the coin. A coin treated this way should weigh almost exactly the same as it did before any silver sulfide was formed.</p><p><br /></p><p>I&#039;m looking for a good candidate to try this process on - a nicely toned coin which wouldn&#039;t cost me much if I kill it. I already have a couple of extreme tarnish examples for a worst-case scenario attempt, but I want one which, if the process is successful, would become a very appealing coin.[/QUOTE]</p><p><br /></p>
