L'Aventure des low-tech en Amérique du Sud

This oven fabrication technique was documented on during one of our trips, looking for low-techs in South America from June to September 2017 in Ecuador, Peru and Bolivia.
This oven, used in the Finca Fina farm near Malacatos in Ecuador, can cook all sorts of foods with just a small amount of wood. It can store heat sufficiently and once it's hot, it can carry on cooking dishes for a considerable amount of time without being maintained. The fact that only a little fuel is used, is an advantage for regions where there isn't much wood. On a certain scale, this advantage helps reduce deforestation due to the use of wood for cooking. The low consumption of wood prevents the user from travelling as often for a supply of wood.
Easy to make, some knowledge in masonry is however needed, one part is made out of bricks, displayed to form an arch. Certain metal parts need to be welded, so welding skills are also recommended.
• A metal canister of at least 30 cm in diameter
• Some bricks 4 cm thick maximum
• A big bucket • A metal pipe 10 cm in diameter (the length depends on the height of the ceiling in the house and the chimney must exceed the roof by at least 30 cm). • Soil (clay soil if possible) • Cement • A grill whose width is slightly smaller than that of the canister • Wire mesh less than 0.5 cm
• Wire cutter
• Trowel • Welder (if necessary) • Wood saw • Shovel
• Build a solid wooden table. Shape it so the canister can be laid down on the middle of the table and so that 30 cm are left on each side of it.
• Make a square-shaped hole in the middle of the table 20 cm*20 cm • Cover it with an even layer of mud 4 cm thick
• Lay the bricks on the surface of the table without covering the hole. The surface must be the straightest and most horizontal possible.
• Lay the canister on the middle of the table, horizontally. It must be slightly raised so the air can circulate underneath. • Build a cement-brick arch in order to cover the canister, leaving a 10 cm space around it. Leave a 10 cm hole on top of the arch for the passage of the flue. • At the end of this stage, only the opening of the canister should be visible.
Une fois que la terre est bien sèche :
La chaleur que diffuse le four peut permettre de réchauffer la pièce.
