<p>[QUOTE=&quot;desertgem, post: 580200, member: 15199&quot;]A misleading conclusion. Of course there was more weight loss in the first dip, because the dip&#039;s chemical composition is designed to remove the oxidation product such as sulfide, acetates, etc. and less of the&nbsp; associated silver layer, whereas following dips only removes original silver content of the coin since the oxidized products were removed in the first dip. And since that is just a byproduct action of the dip it is designed to be weak.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
