<p>[QUOTE=&quot;OldDan, post: 102069, member: 1872&quot;]I&#039;m not so sure about this statement Ruben.&nbsp; There seems to be a few folks at the Smithsonian who would also disagree with this satement, or so I have been let to believe.</p><p><br /></p><p>Talked to a friend who had just returned from a visit to the Smithwonian, and while there was told by one of the people who work there that they use a certain polish on all their silver, gold, copper and copper alloys (bronze, brass and nickel) artifacts on display.&nbsp; They claimed that this was in the form of a wax and it was applied to everything including paper, parchment and you name it and it gets a coat.&nbsp; He was told that it is chemically neutral and contains no acids.&nbsp; These people are in the game of conserving, so should know what they are talking about.&nbsp; He called it Renaissance Wax and comes from England where it is made.&nbsp; I looked it up and found it called &quot;microcrystalline wax&quot;.&nbsp; So maybe there is something that could be used to prevent all the damage that is caused by just laying around in unsafe environments.</p><p><br /></p><p>Having now said what I did, I will admit that I don&#039;t know if they use it on their coin collection.&nbsp; But then again, they view these articles as pieces of display and want them to be as nice looking as they can&nbsp; make them, without having to clean them up every day or two.&nbsp; I may be worth looking into a little deeper.&nbsp; What say you?[/QUOTE]</p><p><br /></p>
