New to the forum. This spring my wife, daughter and myself have planned to build a cob oven over a smoker. Plan on a block base that will serve as smoke chamber, with cob oven on top. We plan on pouring 3" of quikcrete for the structural hearth-then our question comes for the insulated hearth. Cob ovens call for cob base with bottles set in the cob to serve as insulation. If we put bottles in the top layer of cement, will this serve the same purpose? We then plan on setting fire bricks on this layer of bottles/cement. We have decided on the cob oven for a number of reasons-such as availability of materials, ability for the family to get involved, and to see how we like the outdoor oven. I plan on using it as long as possible with someday maybe taking the cob oven off the platform and building an actual brick oven. Your responses are greatly appreciated.
