This oven is a great inexpensive tool for cooking outdoors in an emergency. It is easy to build and use. This homemade oven bakes using only 10-14 charcoal briquettes.
Control the temperature by using one coal for about every 35 degrees desired. Oven will maintain temperature for 45-55 minutes. Slip fresh coals underneath as needed for longer cooking times.
350 degrees = 10 coals --- 400 degrees = 12 coals
