Excuse me, if the thread was already discussed on the forum.
What is the easiest way to remove gold layer from plated base metal, e.g., copper? Several times used nitric to dissolve all the copper, but there is a huge amount of nitric needed to dissolve all the base metals with cloud of dark brown fumes evolving ... Are there other ways to do this?
