 Earth (or clay or cob) ovens are traditional retained-heat ovens that have been used in many different cultures for millennia. Earth ovens use non-fossil fuels – sticks, wood, grasses or brash faggots (bundles of small-dimension twigs). The heat generated by burning the fuel is absorbed into the thermal mass of the oven, and the food is then cooked by radiation (heat radiated through the air), conduction (heat transferred directly from the body of the oven) and convection (the circulation of hot air), all of which comes from the heat of the fuel stored in the thermal mass of the clay. Gas or electric ovens don't have the thermal mass, and cook mostly by convection. Earth (or clay or cob) ovens are traditional retained-heat ovens that have been used in many different cultures for millennia.

-If building a one-chamber oven, there is a precise relationship between the size of chamber and the size of door. More details can be found in Kiko Denzer's book, or you can attend a [course](http://lowimpactorg.onyx-sites.io/directory/categories/earth-ovens-courses) for more information and practical experience.+If building a one-chamber oven, there is a precise relationship between the size of chamber and the size of door.

 NB: earth ovens don't like rain, and so you will need some sort of basic roof, or it needs to be covered when not in use. NB: earth ovens don't like rain, and so you will need some sort of basic roof, or it needs to be covered when not in use.
