<p>[QUOTE=&quot;HandsomeToad, post: 535386, member: 12965&quot;]I still wonder if you know what part of water (H2O) causes the corrosion? The video was interesting, in that the penny was submerged and yet it dissolved away and no &quot;AIR&quot; nor WATER touched the coin, but Oxygen was present. :whistle:</p><p>&nbsp;</p><p>Ribbit <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p>&nbsp;</p><p>Ps: Take issue we me all you want! <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" /> I love a good argument. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /></p><p>&nbsp;</p><p>Ps: On your last comment, I&#039;ve noticed that after I clean a copper, if I don&#039;t coat it right away it will start corroding again, and there are no sulfides involved. Furthermore, sulphates are what cause the copper to turn brown (patina) and that&#039;s a form of sulphur.&nbsp; <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
