Progress!

Both the masking techniques we tried for the silver etching look promising, although I want to try them again with a narrower line before actually etching. Fabulous! In general, one's risking losing detail, so being able to go for more detail is great.

I got a casting back from the casters, but they didn't "patinate" it as we had requested. On the plus side, they didn't charge us for doing it, either... still, that means I have to do it, and I don't currently have the materials for is, since the thing in 14k white gold, and it really doesn't oxidize. I'll order the materials I need tomorrow, and meanwhile can get the jump ring soldered onto it so that it will hang properly when on a chain.

The bail and the loop are now on my plique smiley. In addition, I've wired the bail together to minimize the risk of things slipping if it gets past the melting point of hard solder in the enameling process. Now for the depletion gilding...

I fired the cloisonne smiley again, and think I'll just go with this one. At least I'll start finishing the enamel, and then see. I think it's OK- not utterly splendidly fabulous, but OK, and quite suitable for the purpose.

I riveted the trillium pin together with a tube, and drilled a hole and fitted a wire for the stabilizing rivet. I'll get that seated, then get the stone added and that one can get photographed and go up on my site and/or Etsy.

As usual, other bits were accomplished, but that's the gist.

It sounds like something was precipitating out, so some sort of non-dissolving compound was being made in the etching process. This might be why we used the electricity- it would force the reaction in a certain way, probably one that would not otherwise had happened. I wish I were not so many years away from my chemistry knowledge, or I'm sure it would be more clear to me!

I think the sulphuric turns blue because of the copper in sterling. Or did it also do that if you used only fine silver in it? I know that when the silver pickle is pretty blue, you can force a copper plating on stuff- whether or not you want to!- by putting it in the dirty pickle with some steel...

Hmh, I have never used fine silver, unfortunately, so I don't know.

Yeah I had that copper plating in not-so-good steel tweezers, they turned pink on the tips, hahah.
