Obvara and Slip Resist Naked Raku Workshop

in ,

I just got back from another raku workshop at Dakota Potters Supply in Sioux Falls, SD! I brought along a group of faculty, alumnae, and students from Morningside University.

This workshop specifically focused on obvara and slip resist naked raku. I really like obvara, but since I just did a bunch in the fall, I only put four pieces through the obvara process and ran ten through two slip resist processes: one-step and two-step slip resist. Dakota Potters Supply had tried to troubleshoot the slip resist one-step process in advance of our workshop, but they really hadn’t figured it out so we were all experimenting and troubleshooting with our the slip resist attempts throughout the day.

I still need to edit the photos of my pieces - plus, two of them were underfired enough that Dakota Potters Supply kept them back to refire again later, so I don’t know when those might rejoin me (if they stay whole)!

Here are photos from the day of the workshop (Saturday, April 20, 2024):

April 2023 Raku Crackle and Saggar Ceramics

in ,

This is my second post reviewing my April 2023 raku workshop ceramics! This one will cover two of my three “baked potato” aluminum foil saggar-fired ceramics and my clear crackle piece.

Based on my experimentation using plants at my April 2022 raku workshop, I only had real luck with saggar firing Muehlenbeckia axillaris, colloquially known as Creeping Wire Vine. I therefore used it again! Below is a plate that was dipped in three coats of ferric chloride and then wrapped in the vine and then aluminum foil and fired. The Muehlenbeckia axillaris impact is relatively subtle because it mostly went white to medium gray, but the plate overall turned out well. The very first time I did this “baked potato” technique, I used a matte clear acrylic spray. The second time, I went with gloss. I didn’t really love either, so this time, I went with applying a kitchen wax. I really like the way the wax looks, so I think that’ll be the winner moving forward!

Next, I did the same process with a vase - on this piece, I also sprinkled just a little sugar on as well for some small-scale spotting in the design. This one’s interesting as the Muehlenbeckia axillaris is more apparent, and it produced the full value spectrum on the same vase; the top vine piece is white to light grey, while the bottom vine carbonized a lot more and turned medium grey to black.

And finally, I chose to do a clear crackle on a small, necked vase. Handbuilding necked vessels is tricky, and I complicated matters with this piece by leaving my building process evident on the outside to contribute texture (while smoothing it for structure and stability on the inside). This was quite risky; I knew there was a good chance this piece could crack or break with thermal shock due to the thinner seamed areas. However, I was fortunate - it made it through the firing completely unscathed! I wanted to enhance the seams and stress spots that I had intentionally retained, so I painted over each of them and the lip of the vase with wax before glazing with Clear Crackle on the exterior. As I’ve explained before, this means the glaze doesn’t stick to the waxed areas, and the wax burns off in the kiln. The exposed, unglazed clay body then carbon traps the smoke in the post-kiln reduction atmosphere, turning a dark, smoky grey. I finished the piece by putting kitchen wax on the unglazed areas.

Again, none of the “cracks” in the below piece are structural - they are all decorative and this vase is fully sound.

April 2023 Raku Copper-Glazed Ceramics

in

I’m going to do a few different posts about my April 2023 raku workshop pieces because there’s a lot of good work to share. In this first one, I will review my copper-glazed pieces!

Below is a platter, which has some texture on its surface; I imprinted an equine femur into the clay body thanks to bones I was allowed to keep using from the LSU SVM anatomy lab. I first glazed it with White Crackle, then wiped the white crackle back down so that it stayed in the impressions, and also applied it to the rim. Then I glazed over the top with Copper Sand. I thought this would impact the coloration, but the white crackle (at least at that thickness) only really affected the sheen; where it was applied the glaze is glossy rather than matte. Though it’s not precisely what I envisioned, it’s a strong piece.

Next, we have a small, leaning vase. I chose to apply wax to the rim and throat. Then I glazed the exterior with Copper Sand, keeping in mind that the glaze doesn’t stick to the waxed areas. In the kiln the wax then burns off, allowing the unglazed clay body to carbon trap the smoke from the reduction afterwards. I was planning on staining the raw clay, but I ended up holding off as the variably smoky surface is interesting in its own right. I need to actually decide, as I will want to wax the raw surface if I don’t stain it.

This is probably the biggest of my raku pieces this go-round. This vase vessel has Litho Carb on the inside and Copper Sands on the outside. (I really like Copper Sand as it’s pretty predictable in its behavior for me, which is a rarity when doing raku.) The interior lip has an abalone-like appearance!

Next, we have my “golden bowl.” This piece is glazed with Dakota Potter’s new Peacock on the interior, and once again uses Copper Sand on the exterior. One of my students kept hovering her hands above it and singing reverential “aaah” noises!

And below is my final copper raku piece of the workshop! This one is an oddball shape; I wanted to push myself to make some handbuilt, necked vessels and in doing so created this flora-inspired vessel. I glazed it with Litho Carb on the inside and Midnight Luster on the outside.

This show will run from October 24-31, 2021 from 6:30-8:00pm, if you’d like to stop by and check it out! Entry fee to the exhibition will be $2 for VAAC members or $5 for non-VAAC members. Masks will be required.

Cross Off Another Bucket List Item: I've Done Raku!

in , ,

I’ve always wanted to do raku firing ever since I first saw a piece of raku pottery and learned of the technique as a child - but it’s never been an opportunity I could take advantage of until now! A few months ago I attended a Saturday raku workshop at Dakota Potters Supply in Sioux Falls, SD, joined by my ceramics faculty member Paul Adamson and graduating senior Anna Uehling. Raku, first practiced in Japan, is a low-firing technique that makes use of wide temperature swings, reduction, and carbon trapping to create some really ornate artwork. Due to the low-fire nature of the process, the pieces are mostly decorative; they are neither watertight nor food-safe.

Here is a slideshow of the day’s adventures. This post will be followed by a series of posts exploring each of the three different glazing techniques I tried! There were five different techniques available, and I was most interested this first go-round in three of them.

  • Crackle glazes (either clear or white), with the goal that carbon gets trapped in the crackles

  • The “baked potato” technique, wherein you coat the bisqueware in ferric chloride, sprinkle it with sugar, salt, and/or horsehair, and then bundle it up in aluminum foil like a baked potato before firing it

  • Copper glazes

  • Ferric chloride spray

  • Horsehair and/or feather application
