Outdoor pizza and bread ovens are becoming more and more popular, especially small DIY sized ones for the back yard.
Wood-fired ovens are distinct from wood-fired stoves that have a hot cooking surface for pots and pans, like on a gas or electric stove. A wood stove may also have an oven separate from the fire chamber. Regardless of material they all have an oven chamber consisting of a floor (or hearth), a dome and an entry (oven opening).
This design is brilliant. The builder uses an exercise ball for molding the basic shape, and built this pizza oven for about $ 135.00
