Pickling.I use the copper tongs I’m making to retrieve items from the pickle pot. Picking is a metal cleaning technique for removing oxidation. In this case for non ferrous metals such as copper, bronze, silver and gold. Regular steel tongs would cause a weak current to superficially plate copper onto the items in removing oxide from. #pickled #pickel #sparex #frontstepforge #blacksmithtools #copper #hollowform #raising #blacksmith | Front Step Forge
