<p>[QUOTE=&quot;imrich, post: 7603516, member: 22331&quot;]As a scientist, educated/practicing in the crafts/professions for more than 70 years since 9 YOA, constantly working in challenging positions through-out the world to solve unique problems, I intuitively would agree with your thoughts. But, from experience, I know better. I&#039;ve received numerous awards/patents, to only understand the process, but not to create an absolute uncontaminated atmosphere. Unless one knows all of the environmental parameters of a process, virtually nothing can be guaranteed.</p><p><br /></p><p>Microscopic contamination exists virtually everywhere, as I know from high-vacuum processing in virtually sterile facilities.</p><p><br /></p><p>Early in my vast Numismatic education I &quot;hair-lined&quot; destroyed several flawless specimens of &quot;fine material&quot; P.M. using lubricated &quot;Q-tips&quot;.</p><p><br /></p><p>I live in a 1st-growth forest sealed home, ~70&#039; above a &quot;white water&quot; river, ~15&#039; below, and 1/4 mile from a well traveled rural &quot;dirt&quot; road. I watch the effluent clouds from vehicle travel, rise/travel downwards through my thick woods, causing layers in my home. Do you have an idea how hard some of those microscopic particles may be?.</p><p><br /></p><p>I suspect road dust may cause scratches, although unseen with the human eye.</p><p><br /></p><p>JMHO[/QUOTE]</p><p><br /></p>
