Two Day Intro to Bronze Metal Clay

Posted by C Scheftic on 2016/07/24

Another workshop I have coming up is one I’m calling Golden Bronze Beauties! It is this week! And there are only a few seats left! (Click the link in the class name to get to the official announcement and registration pages.)

This workshop will offer a simple introduction to working with bronze metal clay. If you’ve been wondering about metal clay, I hope you’ll jump in with this one. Or, if you’ve already worked with silver clays, this will be a great chance to explore a different formula. (Should you know enough to wonder about this, the clay I’ve chosen for us to use in this session is Hadar’s One Fire Brilliant Bronze.)

Everyone will be led through the process of developing your own unique, reversible design for a pendant and / or a pair of earrings, and then working with bronze clay to implement that idea.

This is a two-day workshop! Most of the classes at the Artsmiths of Pittsburgh (at least so far) have been one-session-only events. But I asked for two so I could offer one using bronze, and was delighted when they agreed to try this!

We’ll do all the making on day one. I’ll fire everyone’s pieces overnight and, in the second class, we’ll see how they all turned out, and explore a handful of finishing techniques. With all the base metals, there can be surprises in how they come out of the kiln. On the plus side, your piece may have acquired one of the stunning, but unpredictable, “kiln colors” that, although ephemeral, you may want to try to preserve for as long as you can. Alternatively, it may come out a dull tan or gray color, one that you’ll want to polish off your piece to reveal the golden-bronze color underneath.

Kiln-colors? Consider the photo of three small hashi oki (chopstick rests) that I made several years ago. While the pendants and earrings in the “promo shot” for this class have all been polished to a high shine, two of the three of these rests came out with such beautiful kiln-colors that I couldn’t bear to polish them the same way I did the third one. (I still have these: I actually use them in my studio as dohgu oki (tool rests) to keep brushes and burnishers and other round-handled tools from rolling off my workbench!) I have polished the bright one lightly a few times, but have let the colored ones slowly darken with age naturally and they are still lovely!

Alternatively, on this butterfly pendant with bronze wings (and a copper body), I left kiln-colors in the hollows of the texture, while selectively polishing the high points. That’s the thing with bronze: you can be determined and just polish the whole thing once it’s been fired, no matter what, or you can wait to see what the kiln provides and make your final finishing decisions based on what you’ve been given. Leading you through those options will be the focus of our second meeting this week.

FWIW, that is why all my base metal classes are longer than a single session. If we use just a single metal (bronze, copper, or steel), we meet at least twice: once to cover making and again to cover finishing. And when we start to combine metals, we meet at least three times (more is even better). Mixing metals increases the chance that the pieces will come out of the kiln with some cracking that will need to be dealt with on our second day (i.e., given some simple repairs & refired, and/or otherwise designed-around). Thus, with mixed metals, we need at least one additional day to ensure that everyone can complete their final finishing steps too.

Important Note!

I’m really hoping that this offering garners a good bit of interest! (This, and a four-day one I’ll discuss in my next post: an introductory silver class covering a range of techniques, including several for incorporating some bling that we often skip over in single-session lessons.) If Artsmiths sees that there’s interest in being able to “go deeper” in these processes, that’s what it will take for them to let me offer more like this! If you are interested, and can join us, please do! If your interest has been piqued, but you just can’t make it for those days (or at those hours), please let the folks at The Artsmiths of Pittsburgh know: we can modify the scheduling for future sessions if we know what would work better! (And, if we can’t make the timing work in their classroom, I can offer the same thing at my own studio.)
