Spraying the Soda

 I get a lot of questions about how soda firing works. It's pretty simple, really: when the kiln reaches ^9, I spray a mixture of baking soda, washing soda, and water through ports built into the kiln wall for that purpose. The sodium in those compounds turns into a glaze on the ware (and everything else in the kiln.) I use draw rings - little loops of clay - to determine when I have sprayed enough soda into the kiln. Pulling the draw ring out through the spyhole is my favorite part of the process! Well, except for unloading.
