<p>[QUOTE=&quot;rysherms, post: 1769876, member: 46631&quot;]no, chris of coin armour is not a chemist, and his links are to his own site and the manufacturers that make claims aligned with mine, he simply misunderstands them. he sells a product that claims to absorb chemicals when the manufacturers statement clearly says it is a barrier.</p><p>&nbsp;</p><p>also, if you could show me one reputable article stating that oxidation and silver sulfide are the same thing i will very calmly apologize and tip my hat to you. i believe the entire University of Florida dept of materials engineers would disagree with you, but hey, we are only the number one rated materials engineering program in the country, what do we know about chemical reactions as clearly defined as tarnish (Ag + H2S) versus toning/oxidation (Ag + O2).</p><p>&nbsp;</p><p>one chemist briefly commented on another thread here agreeing with me. he is a very respected member and i will not drag him in unless he wishes to re-comment. i have yet to see something reputable argue with the CHEMICAL EQUATION defining sulfur reactions and oxidation.</p><p>&nbsp;</p><p>i will keep an eye out for this endless list of numismatists, books and articles claiming that two separate chemical rections, with different REACTANTS are the same thing......</p><p>&nbsp;</p><p>WOW[/QUOTE]</p><p><br /></p>
