This was my first time doing slip resist naked raku ceramics, and it was definitely a learning process for everyone at the workshop, with more experimentation still needed moving forward! I did a fair amount of research the night before the workshop, and I was really glad I did. When we arrived the plan was just to do a one-step slip resist, but I had discovered David Roberts’ ceramics and wanted to try his technique. That required a two-step process (step one: dip into the slip resist, then let dry and step two: dip in clear glaze), which I convinced Wanda to let me do as well.
We began with the one-step system, but it was producing very low-contrast results for everyone. Some of them are still very cool, but I really wanted some full value finishes! As we fired the first of the two-step pieces, we saw that it was garnering better results. We’d already gotten through the majority of the slip resist pottery by then, but we pivoted the last third entirely to the two-step process regardless of whether folks wanted to carve through it. You may recall my last two pieces didn’t get fully fired, so I left them with Dakota Potters to refire another day. I recently got them back and in my opinion they’re the best of the bunch!
I put ten ceramics through the slip resist process; three were one-step and seven were two-step pieces. Unfortunately, we did find the two-step pottery were more likely to suffer casualties in the kiln. One of my two-step ceramics shattered so fully that it was just trashed there. Another blew a chunk of its side out, but is otherwise actually pretty cool so I plan to use a rotary tool to sand down the jagged edge and keep it.
Below I’ll show my eight undamaged pieces! First, two views of my first David Roberts inspired dish wherein I carved through the two-step surface to leave black lines:
Next, one view each of a one-step vase and bowl:
The below orb was also a one-step piece, but I added wax resist to the rim before dipping into the slip resist. Despite its low contrast, I think the pure black rim, the high burnish, and the shape contribute to making this one of my favorite pieces from this workshop. Here are three different angles of it:
Next, we have one image of the largest piece I fired at this workshop, and two views of another attempt at carving through the two-step surface on a small tray.
Here is the first of the two pieces I left behind to get refired - a large two-step orb!
And finally, the second of those two, an oblong vase:
Overall, I’m quite happy with these results so far, though I’d like to figure out how to regularly preserve larger white areas for even higher contrast. My burnishing was more successful on some pieces than others, but I do think it was worth the effort and I plan to continue to burnish for naked raku ware.
