Tinning two sides

The chemical 'electroplating' to which you refer is probably what is called 'pickling' in jeweler's terms. This is where you dip a base metal in a solution, which leaches off the surface atoms, which subsequently attach themselves to the next higher metal put in the solution.<br>
Apparently this does not always require jeweler's pickle (which is a retail product); cleaning solutions can take silver and accidentally coat gold with it; this is a problem at my daughter's shop.<br>
There are quite a few types of chemicals that might be involved, but it could be an alchemist's secret for turning a base metal into gold.<br>
I am reminded of Archimedes 'eureka' solution (no pun intended) about the problem of the composition of a gold crown. <p>Legio XX<br>
