A few weeks later…
After having made some flat breads, there were just a few coals left in the oven that were all the way to the back. I stuffed the oven with some large chunks of wood to dry out, inserted my bake door, and I was done.
Surprise. The next morning I looked out at the oven from my studio window, and the door was gone. No big deal I thought. Probably it just fell off on to the ground, I wish. As it turned out, there was enough residual heat in the oven to ignite the logs and totally destroy my bake door. Never again will I incorporate wood into a bake door design. I am going to try making a door with mineral wool sandwiched by two layers of metal. When I have this worked out and functioning, I’ll post a photo.
