Larry then built a form for the insulating layer and the hearth slab. These are poured one after the other.
It all went like clockwork. This has been so much fun. And there's still a lot of work to do! I love working with Larry. He is intensely focused, but still a lot of fun to work with. This is our first oven - we plan on building more: one more on our property in northern Minnesota, but we'd love to build for other folks, too!
