I built this kiln in 2002. I modified plans given to me by my friend John Fulwood of Kissimmee Pottery. I built it quite small for several reasons. First, a big kiln takes big shelves. Big shelves can get awkward and heavy, especially when you are building the top of the stack. The second reason is that with a small kiln, I can fire quite frequently, and thereby see the results of experiments before I forget what I have done.
