I've been playing around with some argentium this week. So far so good! I've started on some lovely earrings but just now realised that I need to finish them in a different way to sterling. Oven heat them, ultrasonic cleaners, tumbling...all new to me! Could someone please point me in the right direction and give me a simple run down of what I need to do in order to finish my pieces? I currently don't have an ultrasonic cleaner OR tumbler. Do i need both or with one do the job? As you can tell, I'm very new. Thank you for any help.
