Hi Lee,
Forgive my ignorance, but could you please explain what you mean by the
statement "silver inventory is increased many times over"? Are you meaning
that the deposition thickness of electrolytic silver is higher than that
found for immersion silver thereby allowing for an increased risk of metal
migration?
Best regards,
Joe Russeau
