The next stage to building these ovens is to make a separate fire chamber Below the baking surface, with holes ( small- very small holes-- leading from the fire chamber- where the wood is burned, up to the baking chamber. A chimney is built in the back large enough to draw the smoke out of the fire chamber, so that the smoke does not flavor the baked bread too much! :rotf:
In these ovens, its imperative that very dry wood is burned in the oven, so as to not coat the roof of the oven with Unburned pitch and tars, that is "stuck" to the roof because of the steam( moisture) in the wood. The biggest problem with this design of an earthen oven is its tendency to develop cracks if the clay takes on moisture between uses, and is then overheated. The Thicker the clay dome, the less likely cracks will develop, and the longer the oven lasts.
Nicely done, BTW. :hatsoff:
The heating of the fire brick, and the thick walls of these ovens so that the heat was retained, and dissipated slowly to allow baking of breads, is the "secret" of these ovens.
A Wooden Door was made to fit the opening, and soaked in water when not being used to close of the opening to save heat. Willow, or poplar(cottonwood, aspen) was the wood of choice- not pine. In the east, White Oak( the same wood used to make barrels for whiskey making) was used. :thumbsup:
