<p>[QUOTE=&quot;desertgem, post: 3046772, member: 15199&quot;]Mercury doesn&#039;t plate , it amalgamates with the other metals. If you understand about metallic bonds ( different from ionic and covalent), mercury alloys with the metal through out the coin ( assuming enough mercury). whereas the process of plating is localized on the surface, no penetration/combining of the 2 metals. If a dentist does a metallic filling, he mixes the mercury and filling metal together. The amalgamating process allows the dentist to squish the mix into the cavity where it forms a tight fit and hardens. Although I haven&#039;t done it, Zinc amalgamates with mercury as well as copper. I am curious what machine the jeweler is using.</p><p><br /></p><p>By the way mercury metallic form on the skin is not as dangerous as usually thought unless it is in the vapor stage or organic compounds. The loonies are the amateur gold miners, that use it and HEAT to separate gold from panned granules.[/QUOTE]</p><p><br /></p>
