<p>[QUOTE=&quot;yakpoo, post: 6653760, member: 18157&quot;]A beautiful tribute to a good friend. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /> ...and a nice pic of you as an added bonus! <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie101" alt=":woot:" unselectable="on" unselectable="on" /></p><p><br /></p><p>My father passed just a few months earlier. He taught me to preserve coins, naturally, as near as possible to the moment they dropped from the die. Dipping is something that has never interested me.</p><p><br /></p><p>If there was a way to reverse the toning process without removing any of the original metal, I would consider it. I&#039;ve posted a method of reversing Silver Sulfide tarnish from silver without removing any metal. I&#039;m still looking for a way to reverse the Milk Spot process, but I haven&#039;t found it, yet. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie3" alt=":(" unselectable="on" unselectable="on" /></p><p><br /></p><p>I have a working theory that Milk Spots are created by residual Silver Nitrate (AgNO3)...from the &quot;parting&quot; process used to separate silver from gold. That would account for both the milky color and the fact that it&#039;s ingrained into the silver. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /></p><p><br /></p><p>There may not be a &quot;cure&quot; for Milk spots but, if true, future milk spots may be avoided with better upstream QA. I&#039;m still trying to understand how Milk Spots can develop over time, though.</p><p><br /></p><p>[ATTACH=full]1268876[/ATTACH][/QUOTE]</p><p><br /></p>
