I am also thinking of adding vermiculite on top of my first “mud oven”, to make it extra more efficient and hot. Mark

I would like to follow your inspiration about this kind of material and build my own earth oven.

I would use Straw or Wood-chips rather than dried grasses. Grass and Hay contain seeds that can germinate or rot.

Congratulation on your cob oven Gerry. Looks real nice. I built my cob oven a year ago with a roof above to protect it from rains. It cooks and bakes really well. The only thing is that it’s very small hence now I am building a larger oven from Rado’s plans.

Mark, I reapplied the outer insulation layer to improve the efficiency of the earth oven. The best insulation for cob oven is made from dry grass (dried on the ground after it was mulched in the cutting process) which is mixed with very soft clay. Mixing in volume roughly 4 to 1 grass/mud. It is easy to place on after the cob is built and it dries fast without cracking. This insulation can be also shaped to give your cob oven some interesting creative look.

This is a valuable information for building bread earth clay cob oven. Especially as you describe the mud with sand preparation and the bottles for building a heat insulation under the floor for the cob is an excellent idea … thus the dense part retains the heat well. Ta Mark
