I mentioned a couple months ago the struggle I have with posting my personal studio fare on a blog I hope to be a place for some discussion beyond technical issues related to my craft. Like I said, I’m comfortable at this point with mingling the deeper thoughts and my personal work. This may change in the future, however, especially depending on what The Aesthetic Elevator looks like with it’s additional contributors.
Then again, I hope this will be a place for future contributors to share their own work as well. So we may just roll with it.
The following images are from a smoke firing in my electric kiln.
A few small funnels, designed to hang.

I’m still perfecting this technique, but it’s coming along. Some of the time I don’t use enough newsprint to get enough color and variation. I’ve begun using other organic matter as well for the smoke, including sawdust, leaves and last night a large dead beetle that seemed to give a nice sheen to one of the funnels.
Adding: Julie asked for more about the technique in the comments below, and I thought I’d elaborate on what I know here in the post instead of in the comments.
I don’t actually know much about the smoking process. I learned of it last year some time on a website, but can’t find that same site again for the life of me. It described the technique well. Other internet references to smoking in an electric kiln are cursory at best.
Surfaces finished with a terra sig seem to take the smoke better than those without. So, in my mind, the first step is to apply a sig to your greenware. After bisqued, apply any glaze that will be on the finished piece and glaze fire. The once I tried firing glaze over the smoke, the smoke disappeared entirely. As you can see above, how glazes react to the smoking process can be very different.
I then place individual pieces on a sheet of foil and wrap them in one or two layers of very moderately crinkled paper, preferably newsprint. Other papers seem to simply gray the surface of the clay. Don’t use too much or too little paper. Leaves and sawdust work as well. Pretty much anything dry and ready to burn can be used with some success. I then wrap the foil around the paper and object. Saggars can be used instead of foil.
I usually only fill the bottom of my old electric kiln with pots or sculptures for smoke firings. I run the bottom element on high for 45 minutes to an hour (an hour is probably longer than necessary), let it cool and remove the works. Some of the smoke will discolor the bottom of the kiln, but this goes away during the next higher temperature firing.
