Hi! I plan to build a small gas kiln to start my first experiments in ceramics. I researched a bit, flipped through some books, and it seemed accessible to me to build a little double crossdraft kiln. This model of kiln, known in Japanese as itte-koi-gama (いってこい窯) , is popular as a wood kiln (the Phoenix kiln or Philosopher’s Kiln) but little used on gas. It looks like a plan for a small gas kiln was published on Building Your Own Kiln, Three Japanese Potters Give Advice And Instructions , but I didn't have access to this book. So looking at some kilns over the internet (1, 2, 3, 4, 5) I made a plan for a kiln to firing in cone 10 for two 12X12 inch kiln shelves, the chamber is 3,1 ft³. I wonder if anyone has ever had contact with such a gas kiln. My main question is about the size of the chimney. The models I saw didn't have a big chimney, which leaves me wondering about Fred Olsen's rule. What do you think? I was thinking of building a five-foot chimney. The input size corresponds to the output size and the size of the chimney tunnel. Is it better or safer to have a wider chimney or not? Any comments that might help me in this kiln are welcome, thanks!

From the album: Kilns designed/constructed by John BaymoreA kiln building workshop I ran for the NH Potters Guild for building a combination wood fired and also gas fired crossdraft kiln. Here, the kiln is being built in the early stages.
