Not all metal ovens are Rumford Roasters. Count Rumford (Benjamin Thompson, 1753 - 1814) and his Roasters, picture left, are certainly the most well known, but other iron and tin ovens inserted into the side of the hearth were used in Europe and the United States such as the Reip Oven and Roaster of Maryland, patented in 1825.
Brick bake ovens are heated by burning wood for several hours, removing all the burned wood coals, then just using the heat from the bricks to bake the food. The heat decreases since the burning wood is gone. The oven, pictured below, takes me about 2 1/2 hours to get up to baking temperature.
