Why Soda Firing

The pots in a soda kiln usually don’t have much glaze on the outsides of them, they are glazed by the introduction on soda ash, which volatiles when it hits the flame and creates a glaze. The flame then carries the soda ash through the kiln and the pots become glazed wherever the flame and soda kiss the pots.

Here you see me spraying the soda ash which is mixed with boiling water, into the kiln at about 2200 degrees.

 The results can be greatly varied with this type of firing. For me, that's a big part of the fun of it. You never know with 100% certainty, what you will get from the kilns.

This pot shows where the glaze hit the surface and really added a nice difference in appearance. The green you see is a spearmint glaze that I used inside the pot and along the rim. The soda mixed with that glaze and made it very dark, almost black in some spots and almost white in others. You can also see where it kissed the shoulder of the vessel and the handles. The orange color is from a flas…

A Few From The Soda Kiln

The soda kiln has been unloaded and it was another beautiful firing with lots of great pots.  It seemed like everyone was pleased with the results. Every glaze firing does have a potential for bad pots. I’ve seen pots come out of an electric kiln with some glaze problems for various reasons. Most of those same problems can happen in atmospheric firings like gas reduction, salt, soda, or wood. The possibilities for problems are at the maximum with wood firing but all kinds of things are happening in the soda kiln also, and this can create beautiful pots or pots that meed repair like the one I have to fix from the first firing. You might even remember me writing about them in June. No, I still haven’t fixed and re-fired that casserole. It’s an easy thing to do, I just find it difficult to bring myself to doing it.

The good news is that I don’t have to repair any pots from this firing, I think they all came out great. I was fortunate enough to get some wonderful flashing on most of them.

These pots and more will be at the Piedmont Park Arts Festival this weekend (Aug 15 - 16) in Atlanta. I’ll be in the booth with Kaboodle Home in a lovely spot near the lake. If you’re in the area come out to the park for some great art and say “hi.”

  1. Love those juicy pots! I would love the opportunity to explore soda firing. I hope you have a great sale this weekend.

  2. Whow...great pots. So glad for you. Happy sales!

  3. beautiful pots, have a good sale, I still have my cat, rooster and dog canisters I haven't remade the bottom's (that cracked) over again, I have hard time motivating myself to remake things, I know they'd sell right away if I finished them, but almost out of clay, maybe I should do one at a time and then it won't be so bad.

    1. Thanks Linda, remaking something usually isn't a big problem for me, it's fixing glaze drips and stuff like that I'm less motivated to do.

  4. I'd say there is some great flashing indeed!
