<p>[QUOTE=&quot;SuperDave, post: 2648018, member: 1892&quot;]It&#039;s my visualization that the tools, materials and procedures involved are as much part of the topic as the coin itself, so this little &quot;aside&quot; is firmly in-scope. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p>So, the result of a 24 hour soak. I rinsed the coin by pouring fresh acetone over each face over the original container; quart-size acetone cans have a narrow mouth which lends itself to this efficiently. Here&#039;s the coin now:</p><p><br /></p><p>[ATTACH=full]585305[/ATTACH] </p><p><br /></p><p>[ATTACH=full]585306[/ATTACH] </p><p><br /></p><p>[ATTACH=full]585308[/ATTACH] </p><p><br /></p><p>[ATTACH=full]585309[/ATTACH] </p><p><br /></p><p>[ATTACH=full]585310[/ATTACH] </p><p><br /></p><p>Absolutely no change, factoring the minor differences in the images caused by the first set being shot at night and the new set during the day with more ambient light. Some of the areas of green color are thin enough so that a simple soak - were they PVC plasticizer - would have removed them. Therefore, we know what we&#039;re up against.</p><p><br /></p><p>I&#039;m going to keep the coin in acetone until the Verdi-Care arrives, 24 hour soaks, just because I can and in the hope of dessicating the verdigris somewhat. And start looking for the nearest hawthorn tree/bush. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
