<p>[QUOTE=&quot;Info Sponge, post: 768673, member: 20538&quot;]Wonderful article: that&#039;s the sort of thing that makes me save a magazine when it appears&nbsp; in print. </p><p><br /></p><p>Being me, I of course still have a question. If dipping solutions don&#039;t affect the underlying silver, how do they damage the flow lines?</p><p><br /></p><p>I remember from one of Doug&#039;s many informative posts that the timing of a dip is critical. Is it that a brief dip doesn&#039;t materially affect the bulk of the silver, but still has time to dissolve the exposed and stressed metal of a flow line?</p><p><br /></p><p>If there were&nbsp; a chemical that somehow dissolved or dissociated silver sulfide without affecting silver (there must not be or people would be using it) would it leave luster intact? Or would the sulfide attack already have ruined it?[/QUOTE]</p><p><br /></p>
