POLISHED HAMMER AND POLISHED ANVIL FOR BEAD FLATTENING
According to ISO11426, after cupellation it is necessary to flatten the bead with a polished hammer and polished anvil before laminating it. . This is necessary to maximise the surace of the bead and to do a proper parting process.
If the bead is not flattened and laminated , there is the risk  that some silver remains secluded into the gold, and therefore the parting process with boiling nitric acid would not be 100% effective.
