I put this most together last week but didn’t manage to post it before heading north for the weekend.
As I mentioned in my last post, I fired my first soda kiln of 2009 last Sunday. I unloaded it on Wednesday between classes and managed to snap a couple of quick pictures in the process. We’ve been having some crazy weather here in Chicago that has kept me from going back to my studio to spend some time with these pieces and to take more pictures. We’ve had back to back to back snow storms and it got cold enough for the thermometer to hit -15°F. That meant that I didn’t get back to the studio to take some decent pictures before heading out for a road trip, but I thought I’d share a quick sneak peak from the unloading.
I’m hoping that I can figure out a way to capture the surface of this piece. It is full of little sparkly crystals. I’ve never had crystals develop over such a large area in this kiln before. Of course you can’t see them in this picture, but you can see the kiln wash splattered floor in the background!
This is one of the espresso cups and saucers that I mentioned before. This sweet little cup is maybe just under 3″ tall. While I was unloading, I discovered that one of these saucers mysteriously made it into the kiln without any wadding… oops!
I’m regretting that I didn’t take a pictures that had any sense of scale. This teacup is much larger than the espresso cup above.
This firing was all part of a large dinnerware set from a wedding registry that I have been working on for my friends Beth and Lars. Hopefully I’ll get some better photos of the set to share here soon.
As promised, here are some photos of some recent work. I got them out of the kiln right before our July road trip. And had the photographed this week by my photographer, Guy Nicol.
This is some new dinnerware that I’ve been designing:
And this is part of my newest platter series:
I’m really excited for these new wall vases.
These pieces are sort of a hybrid between my oval vases and the wall pieces.
And this is a new surface that you’re going to start seeing on more of my pieces.
I’m really excited for a floral designer to go to town with them! Unfortunately, my favorite designer, Amy Lemaire, has moved away! Amy has done all the arrangements over the past 4 years. You can see some of her past work here.
I think I’ve mentioned before that I’ve been in a cup making groove.
I really love the curve & tension in these handles.
I thought that it would be fun to try to round up as many online resources for folks who are interested in soda firing and put it together into one handy post. Since there isn’t that much publish (relatively speaking), I think it has the possibility of being relatively comprehensive. I hope you enjoy reading the results of my research as much as I did!
You might remember this site that is all about Salt and Soda firing that I wrote about a while back. It’s a social networking site for all people interested in these firing processes. There are some fantastic potters and sculptors that are a part of this site as well as students who are just beginning to dabbling in soda. I highly encourage you to dive in- sign up and make a page. The more the merrier (don’t be shy if you’re just beginning in soda!) There are recipes for slips and glazes as well as a forum for putting questions out there. Are you thinking about converting an old electric kiln into a soda kiln? There’s a discussion going on here for you. And this site is always evolving- it’ll be whatever the members make it.
Salt & Soda tags on the ClayArt archives on Potters.org. It’s worth digging into. It’s quite possible that someone else had the same exact question as you 8 months ago.
Blogs that focus on soda firing: (I had to draw a line somewhere… so I drew it at soda firing bloggers. If I’m missing any, please let me know!)
Of course there is this blog, PotteryBlog.com. About 95% of my pots are soda fired, and I try to share with you interesting soda information. Soon I’ll be posting a whole bunch of information about the use of whiting in my soda mix (the soda geeks will be psyched for this one!)
Here are some posts that you might find extra interesting if you’re a soda firing fool: What is Soda Firing A Happy Soda Firing Hot Pots
Julie Rozman, a fellow Lillstreeter, also writes a blog, Design Realized. She shares a lot of her glaze testing and firing info on her site. You should be sure to check it out!
Scott Cooper makes beautiful wood & soda fired pots. He also writes about his work and process in his journal, This Week @ St. Earth. You should also be sure to check out his “process” page where he has tons of information that is interesting and helpful.
Keith Kreeger makes salt/soda fired pots at his studio/gallery on Cape Code (although he has been venturing into earthenware lately). You can learn more about his soda work on his blog, Kreeger Pottery Blog.
I just discovered Joy Tanner’s Blog. I’ve gotten to know Joy’s work through the Salt/Soda group and I’ve excited that there is another soda firer writing a blog!
Websites that have a wealth of soda info on them: (These are sites that have information on them about soda firing- kiln info, recipes, etc…)
Julia Galloway’sAlchemy page. Julia generously shares with her information on cone 6 soda firing, including slip and glaze recipes.
Scott Cooper (as mentioned above) has a great process page with tons of information on kiln building, glaze recipes and even clay recipes. Not to mention some beautiful pots!
Robbie Lobell makes beautiful, elegant soda fired ovenware and tableware. He has a page on his site about his kiln and soda firing process. He lives in Coupeville, WA mentions on his site that he will rent out 1/4, 1/2 or the whole kiln to experienced firers.
Books on Soda Firing:
Soda, Clay and Fire by Gail Nichols is a must have for anyone interested in firing with soda. This book is the culmination of Gail’s PhD work in soda firing in Material Science at Monash University in Gippland, Victoria, Austrailia. The research is incredible and it’s an easy read. Two things that don’t always go together so easily. I think if you picked up this book knowing clay, but not knowing soda, you might decide that you need to start soda firing by the end. But I’m a bit biased on these things. You can also learn a bit more about this book here.
Ruthanne Tudball’s book, Soda Glazing is the original text on soda firing. There has been so little actually published on soda (especially in comparison to other firing techniques) because of the youthfulness of the process. This is a book that I kept close to me for many years. There are overviews of different potters and their soda approaches as well as a great index of glaze, slip and clay recipes. Again, this is a book that you need to have on your bookshelf if you’re making soda fired work.
Videos about soda firing: (if you’re reading this through your email or a blog reader, you’ll won’t see the videos below. Just head over to Pottery Blog to see the videos)
From Pottery Northwest:
And a series of 3 informative videos fromJeffrey Huebner:
I really have enjoyed this. Please send me links to things that you think might be missing from here and I’ll keep updating this post. This was a big project and I had to put some sort of limits on it. I decided not to include links to soda firing potters & sculptors in this post. I know that there a ton out there with great websites, but I thought I’d limit it to sites that had technical information on it. Another post will be soda firing ceramicists. That will be fun ; ) If you want to give me a hand with that, just leave a comment with suggestions for me to include. Just remember: folks who fire with*soda* or *soda/salt,* but not just salt.
I fired a kiln full of pots last week in the soda kiln. It was chock full of cups, but that’s the subject of another blog post. It was a pretty fun load. There were a couple of new clay bodies, new glazes and slips. Lots of testing and playing around led to many late late nights at the studio in preparation for this kiln. I ended up with was about a kiln and a half full of work, so there will be another one soon!
The image below is of the wall of the soda kiln. Isn’t it beautiful? The walls are actually glazed. I’ll write more about this soon, but basically the idea is to glaze the walls of the kiln to help protect the bricks from the soda and to pre-season the kiln so less soda can be used from the first firing.
This is what the back of the kiln looked like before the firing:
And this is what it looked like after:
The back third of the kiln is usually has less soda than the front. I load porcelain or white stoneware clay bodies in the back of the kiln that do nice things with less soda to take advantage of this area. If I try to put my soda body in the back of the kiln it will be rough and dry. Not a nice look. I also load the kiln more loosely to encourage the flame to head back there.
And this is the front of the kiln before:
And this is it after:
The kiln had mixed results for me. The pieces that I’m excited about I am really excited about. The ones that did not turn out so well are disappointments. But that is why I do soda. I’d much rather have the highs be really high and the lows be really low than to fire a kiln and say “oh, that’s just how I thought they’d turn out.” And when you have a kiln that you’re doing lots of experimenting with, those extremes are even more extreme. There will be lots of pictures to come, but I thought I’d give you a peak and some of the cups.
Please excuse my less than excellent pictures. I snapped them quickly in my studio last night as the sun was going down. Snazzy pictures will come in the not too distant future. I want to get better images of the test pieces so you can really see what’s going on.
I love how the pattern accentuates the form on these:
At NCECA I attended a discussion group that has carried on past Pittsburgh and is leading to some interesting post-conference disussions. At this year’s conference, the discussion group, Salt Firing Verses Soda Firing was led by Joyce Centofanti. One of the other attendees, David Hayashida, came up with the great idea creating an email list so we could continue our discussion and share recipes and techniques after we returned home. David put the list together and there was instantly a lot of information being passed around. Another participant, Pamela Theis, decided to take it one step further and create an Ning group (an social network site) that will allow us to continue to connect with each other, but to invite others out there who weren’t a part of the original group to add to the discussion.
So, if you’re interested in salt firing or soda firing, or even a hybrid, join the group and join in the conversation! It just began a couple of days ago, so we’re really just getting started.
This is my page on the Salt/Soda Firing site, if you’re interested in seeing what you can do. I’m excited about the possibilities with this group. Soda firing is still relatively new so I think that a group like this that will allow us to share, trouble shoot and brainstorm can have a big impact. I hope you join us!
I fired last week. When I’m done glazing, but before I load the soda kiln, I sit down and roll hundreds of wads for the bottom of my pieces. It always takes a ridiculously long amount of time. Time when I’m feeling a bit anxious about getting things done on schedule. When I was rolling my wads for this last kiln, it was a sunny day, and the morning sun was hitting them in the most beautiful way. I took this picture to share with all of you. My happy spin on a less than fun job.
Wadding Recipe for the soda kiln (pretty standard) (by volume):
1 part EPK
1 part alumina hydrate
medium grog to taste (not really, but you know what I mean…)
I roll my wads ahead of time and put them in a plastic container (the ones from the local Thai take-out place are the best). Then I glue them to the bottoms of pots before loading (Elmer’s glue). Breaking up the wadding into steps keeps my hands cleaner and helps me avoid the problem of getting wadding where it doesn’t belong.
A shot of the front of the kiln. It was an interesting firing. I reduced the amount of soda that I added by about 25% or so.
(new) Soda Mixture:
1.75 lbs. of soda ash
2.25 lbs. of soda bicarb
4 lbs. of whiting
Mixed together with 1/4 of a 5 gallon bucket of wood chips. Mix together well, then add enough water (while mixing) to the consistency of oatmeal cookie dough. I add it on an piece of angle iron through the ports on the front of the kiln when c. 9 is soft. (More on this in a future post.)
Below are some tea bowls that I got out of this firing.
Although there is more all the time, overall there is still very little written about soda (soda firing, soda glazing, vapor glazing, etc…). When I come across something that’s written specifically about soda, I get really excited and I want to share my find with all of you.
I recently came across this great article on the Australian ceramics website Avicam: Why Soda Glaze? It’s a lengthy excerpt from Maryke Henderson’s Bachelor of Arts research report from Australian National University School of Art in 2005. It covers everything from “What is soda?” and the historical background of soda to technical information on soda introduction and it’s corrosive effects on kilns. There are profiles of contemporary soda artists as well as a statement about Maryke’s own work.
The photos that I have included of Maryke Henderson’s work are from Avicam. They are elegant pieces that both intrigue me and make me very nervous. Enjoy the article and the beautiful images. When you’re done reading Maryke’s article, spend some time wandering around Avicam. It’s filled with interesting things to read and some really great pots to look at.
I have been creating, soda firing and documenting simple straight sided cylinders with a variety of surface treatments for examples for my classes and this blog. The original idea was to create demos to show students that aren’t specifically “my pieces.” The fun result of this project has been that it’s given me an excuse to return to things long forgotten, or try something new.
Watch out for upcoming tutorials with lots of pictures and slip and glaze recipes.
Wax resist and underglaze/ slip inlay A great way to make a clean line without too much mess, step by step.
Step 1: Paint slip on leather hard piece.
I used several porcelain slips (grolleg mixed with Mason stains) on Lillstreet Soda Clay
Step 2: After the slip dries (no longer tacky), paint wax over entire surface.
Step 3: Using a small loop tool, carve in your lines.
Step 4: Paint underglaze into the carved lines.Step 5: Wipe away any excess underglaze.
This is a great way to get make a nice clean, sharp line in the leather hard stage.
The inside of the piece is glazed with a simple matte black glaze, and soda fired to cone 10 in reduction.
Because the line is inlaid, it’s protected from the soda and doesn’t “bleed” when hit directly.
Soda Firing Fundamentals
This class is for the advanced student of ceramics who is interested in exploring a varied and unpredictable surface for their work. Soda firing is an atmospheric firing that produces flashes of color, a textured orange peel surface, and reacts in a variety of ways with different slips, glazes and clay bodies. We’ll delve into forms that work well to accentuate the soda process, play with surface decoration with particular focus on slips and textures, and experiment with glazing for the soda process (including the use of the spray booth). Kiln loading will be taught and all students are required to share loading and unloading of kilns on evenings outside of class.
Tuesdays, 6:30pm – 9:30pm
Starts Sept. 11, 2007

Advanced Topics in Soda Firing: Surface Decoration
This class is for advanced students with previous experience in soda and atmospheric firing, who are looking to investigate the process more deeply. This class is going to focus on surface decoration in the soda kiln. We’ll explore texture from stamping to carving and how to enhance the surface in soda. We’ll delve into slips from flashing to porcelain with a variety of application techniques. The ultimate goal is to enhance your forms with surface decoration in the soda atmosphere. Open to students who make both functional and sculptural work. All students are required to share loading and unloading of kilns on evenings outside of class. Prerequisite: permission of instructor.
Starts Sept. 12, 2007

I thought I’d share a sampling of work from some of my student’s (past and present) that have come through the soda firing program at Lillstreet over the past couple of years.
You’ll see many have their own websites, or albums with more images. Just click on a linked name to see more!
Here is a virtual tour of the exhibition that I’m currently having at Haus in Chicago through May 6. It is a body of work that I have been working on for months, and had in my head for the last year or so. It is really excited to have the group of work finished and exhibited together. Click on any of the images to see them larger. I hope you enjoy your visit to the gallery…
This is the front of the gallery with my large bottle forms on display in the window.
Here are some images of the installation of the show.
I have a series of squared platters that I really see as canvases. The surfaces are a combination of layered slips, sprayed glazes and the soda kiln.
I have taken the idea of my surfaces being canvases one step further. I have made a series of wall pieces. These are forms that I have been playing with for a while, but this is the first time that I have exhibited them.
And here are some mugs that echo the grid of squares above…
Chicago artist Amy Lemaire designed floral arrangements in my low oval vases. These are pieces that stand alone as sculptural forms, but come to life with greens, branches and flowers in them. This is just a selection of the pieces. I took these photos on a white piece of paper so you could see them a little bit better.
The show will be up until May 6, 2007 if you’d like to see it in person. There is going to be a “Wine Walk” in the Andersonville neighborhood (where Haus is located) on May 6th. We’re going to take this opportunity to have a closing party. If you’d like to participate in the Wine Walk, you can purchase a special wine glass for $20 and you can wander the neighborhood and taste 40 different kinds of wine.
