<p>[QUOTE=&quot;desertgem, post: 513942, member: 15199&quot;]Hi, The scientist has been in me too long to disappear, and I am open minded enough to admit if I have had a misconception. I have used Verdigone(tm) experimentally on many cents I would have tossed or figured as a fraction of value. I have been happy with it and didn&#039;t feel it changed unduly the patina or surface that wasn&#039;t affected by the verdigris. Sometimes what lies beneath the verdigris is frightening, but that is not the fault of the chemical.</p><p>I took some to the lab today and the Ph was approx 9, alkaline solution, not acidic.</p><p><br /></p><p>For my experiment, I need someone(s) to choose the subjects closest to being identical for comparisons. Then the one wihout the verdigris will be immersed in distilled water, and the one with verdigris in Verdigone. I will remove after various periods of time and photograph both for everyone to see.</p><p><br /></p><p>Here are 4&nbsp; 1945s Lincolns, the one with out the number bottom center has verdigris under the shoulder of bust 8-9 c&#039;clock.&nbsp; Pick the number you feel is closest in color and patina to this cent. The top cent has a &quot;2&quot; on it,hard to see.</p><p><br /></p><p><img src="http://i455.photobucket.com/albums/qq279/desertgem/4lincverd.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><br /></p><p>Here are 4 uncirculated 1960-D.&nbsp; I want to see if the surface of an uncirulated coin is affected by similar immersion. Pick the 2 closest please.</p><p><br /></p><p><img src="http://i455.photobucket.com/albums/qq279/desertgem/4lincunc.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>After I get some agreement, I will start the experiment. Suggestions welcome. All photos will be taken same conditions. I have no financial connection with the product or the inventor, except I buy it from him <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
