Its going to be another nice weekend so I'm planning on doing another wood firing. Last week when I was reading Clayart one of the topics was hillside kilns. I had remembered somebody telling me about a "coffin kiln." I think I'm going to try building one of these, a small kiln to fire some raku teabowls. Not sure how I'm going to build it yet. Will just have to dive into the project and get the fire lit. Will post photos next week.
