I have an issue related to cement gold on copper bar, I used water splash but most of plated gold still on the bar, tried to use piece of cotton but it also failed, I just cemented for couple hours, have I splash water each while to avoid gold stuck on copper?
Is it a good idea to put the copper bar in dilute nitric acid so gold foil will dropped after nitric start dissolving copper?
