learning, using & teaching metal clay, and other aspects of life

Maybe I should try a white lab coat?

I was just wondering if being dressed in white might help me in my ongoing struggle to get decent photos of small shiny objects without unwanted colored reflections in them….

In person, I think it’s somewhat more obvious that the design on this intentionally-simple ring involves a butterfly on some flowers, with ferns around the ring-band. The LOS patina came out nicely, with a sort of blue-tint to the butterfly and a sort of rosy-color deep into the roses. I know that the butterfly would stand out more from the flowers if I’d used textures with more contrast, but I’m happy with subtle difference–the camouflage–that I achieved this way. Yet at some point I just stopped counting the number of shots I have taken trying to get one that looks even remotely like what I see. (O the joys of digital cameras with their instantaneous results!) I hope you can see my intended design because mostly what I see here are various reflections on the silver….

Oh well, the important thing is that students in my next ring class, who will be there in person (at Zelda’s Bead Kit Company later this month), can see the points I’ll be making with this and the other dozen-ish rings I’ll be taking to illustrate various aspects of ring-making.

I’ll have two rings (this and one other) that I’ll use specifically to illustrate post-fire sizing. I don’t use the “ring pellets” that seem popular among many metal clay artisans. I understand what they do, but I cannot fathom why they seem so popular. I’m happy to have a ring come out a tiny bit small–in fact, I construct mine so that they come out of the kiln a very controlled amount too small! And I don’t care at all if they do not emerge from the kiln in a perfectly round shape–though mine rarely change shape during firing. Even if I wanted a ring to end up round and it came out of the kiln a slightly different shape, it’s easy enough to get a properly fired-to-metal ring into round, and to strengthen it in the process of getting it to the desired shape.

Once my ring has been fully-fired and, unlike the one shown here, usually before I apply any patina (but my snapshots of the other new, and as-yet-untreated ring, have even more distracting reflections), that’s when I do all the sizing, shaping, and work-hardening of the finished metal to achieve just the fit I want and to give my creation as much strength as possible. In most cases, my ring will end up a bit bigger than it started (meaning it will then fit just right) and a bit oblong or oval (so it will stay put when worn, much better than a round one does), both of which are results that I want. Even if I were to use the pellets, I’d still do all that … so I just don’t bother with them.

Yes, it did take me a slight leap of faith, back in the beginning, to believe that metal clay really turned into a true metal that you could metal-smith. And, yes, I’ve seen people with under-fired pieces that were still too brittle to treat that way. But a pellet isn’t going to solve any of that…. If you’re making rings, especially silver ones, I encourage you to make one a few sizes too small, and fire it for a full two hours, so you can try some gentle yet firm hammering on the edges of the band and around the band itself to see what happens in terms of both size and strength. Bypass rings, in fact, are particularly good for this exploration (better than ones like the construction shown here) because the bypass rings really let you feel how much stiffer / stronger they get as you work them. They are also a bit more forgiving as you aim for a certain size!

If you try this, please do let me know what you find, knowing that another reason I was thinking about the white lab coat is because I look at learning about the metal clay process, and the best ways to work with both the clay products and the final all-metal results, as a series of ongoing experiments.
