Rectangular Barrel Dome is used by professional bakers. These domes usually allow more space so that more cooking can be done in a short time. Moreover, Rectangular Barrel Domes are comparatively easier to construct as this shape only requires the proper alignment of the bricks, and only a small quantity of mortar is required because when the bricks are next to each other, there are hardly any gaps that need to be filled.
The main purpose of an oven dome is to absorb the heat from the wood-fire and then evenly radiate it back to heat the oven and the oven floor, and to cook the food from all sides. For use at home, a Round Igloo Oven Dome proves ideal. It is a bit difficult to construct, as compared to the Rectangular Barrel Dome, and requires more mortar to construct because it has more gaps, especially near the top. But using a high heat absorbent mortar also improves the oven and the cooking as it enables the oven to stay hot for a longer time.
