A cob oven is a type of outdoor oven that is made out of a mixture of clay, sand, and straw, commonly referred to as “cob.” The cob is molded into the desired shape, typically rounded or dome-shaped, and is then fired to harden it into a solid structure.
Cob ovens are commonly used for outdoor cooking, as they can be used to bake bread, cook pizza, and even roast meat. They are known for their ability to retain heat for a long time, making them ideal for slow cooking.
Building a cob oven is often a community effort, with people coming together to gather materials and construct the oven. The process can be labor-intensive but is also seen as a rewarding and creative endeavor.
One of the benefits of cob ovens is their environmentally friendly nature. They are constructed using natural and locally-sourced materials, and they do not require any fuel or electricity to operate. This makes them an attractive option for those who are looking to reduce their carbon footprint and live more sustainably.
Cob ovens are also attractive for their aesthetic appeal. They can be decorated with colorful mosaics or painted in bright hues, adding a playful and creative touch to outdoor spaces.
How to build a cob oven
Building a cob oven is a fun and creative project that can be accomplished with a few simple tools and materials. Here is a step-by-step guide on how to build a cob oven.
You will need clay, sand, straw, water, a metal basket or container for the fire, and a source of heat (e.g. a fire pit). You may also want to gather materials for the chimney and door, such as bricks or stones.
Create the foundation:
Dig a hole in the ground to accommodate the size of your oven and create a level surface. Place the metal basket or container in the center of the hole. Fill the hole with sand to create a stable foundation.
Mix the cob:
Mix the clay, sand, and straw in a large container to create the cob mixture. Add water as needed to create a consistency that is easy to mold.
Build the oven Start building
The oven by molding the cob mixture around the metal basket or container. You can also use a mold or form to help shape the cob. Build the walls of the oven to the desired height and make sure they are thick enough to retain heat.
Add the chimney and door.
Build the chimney by creating a cylinder-shaped structure out of cob and placing it on top of the oven. Create a door for the oven by cutting a hole in the wall and building a door frame out of cob.
Allow the cob to dry and cure:
Allow the cob oven to dry completely, which may take several days. Once it is dry, you can fire it to harden it. Place a fire in the oven and heat it up to around 500°C (932°F) to cure the cob.
Finish the oven Once the cob has cure
You can finish the oven by adding a coating of clay slip or a layer of mortar to make it more weather-resistant. You can also add a decorative finish if desired.
