Polishing ring band/back plate
Hey! I’m relatively new so sorry if this doesn’t make much sense! I have recently bought a barrel tumbler for my sterling silver cabochon rings, when I take them out there are white bits around all the joins, in particular where the ring band connects to the back plate. Should I be doing something pre-tumble that I’m not?
Also, I got the Dremel polishing starter kit but none of the attachments will reach the really awkward places, is there another attachment I can use that will reach them? (I’m also thinking for when I patina the pieces, an attachment that could really get in there and get all the patina off).
I was also wondering what technique people use to get patina really black, as mines not seeming to go past grey.
Many thanks!
