The patching on the argentium ring went very well. it's completely invisible- which I'd expected, but which is still gratifying.
I am not best pleased with Rio Grande at the moment. I contacted them a while back about the enamel that did horrible things when fired, and have not heard back. I even sent an email a week or so ago as well, and... nothing. So I called again today. I would really like to send them the picture I posted here, and hopefully get my jar of yuck exchanged for one that's what it's supposed to be.
