Quick Answer
Best Practices For Building A Sustainable Earth Oven include selecting a suitable location with adequate sunlight and drainage, constructing a base with a mixture of earth and sand, and using local and sustainable materials for the oven's dome and chimney.
Building the Base
To build a strong foundation for your earth oven, dig a pit that is 2-3 times larger than the oven’s diameter. Fill the pit with a mixture of 1 part earth to 1 part sand, and compact it using a plate compactor or a heavy object. This mixture will provide adequate drainage and support for the oven.
Shaping the Dome
Use locally sourced earth to shape the oven’s dome, applying a consistent thickness of approximately 1-2 inches. You can use a combination of hand tools and a shovel to shape the dome, or use a mold to create a more uniform shape. Make sure to leave a small opening at the top for the chimney.
Finishing Touches
Once the dome is complete, allow it to dry for several days before applying a layer of natural plaster. You can use a mixture of earth and water to create the plaster, or use a combination of earth and lime for added durability. Finally, build a chimney using local materials and ensure it is properly ventilated to maintain airflow and prevent carbon monoxide buildup.
