<p>[QUOTE=&quot;lrbguy, post: 2871399, member: 88829&quot;]The statements about verdigris the VerdiChem has given are ambiguous at best and mistaken at worst.&nbsp; As others have said here, Bronze Disease is not to be lumped together with Verdigris on coins.&nbsp; That writer appears to lump them together, and then expounds vagaries in a non-scientific way.&nbsp; I would dismiss those comments and search for more precise statements, since you are asking about the relative merits of distinct chemicals on an indistinct set of problems (i.e. coins with different chemical natures.)&nbsp; </p><p><br /></p><p>Will VerdiChem remove copper acetate?</p><p><br /></p><p>What will Verdichem do with cuprous or cupric chloride?</p><p><br /></p><p>Why is does one of the standard treatments for Bronze disease use sodium sesquicarbonate, which is not mentioned in the list of chemicals to be used?</p><p><br /></p><p>Ask real questions and get real answers, not marketing hype.[/QUOTE]</p><p><br /></p>
