Quick Answer
Primitive pottery can be fired in a campfire, but it requires careful planning and execution to achieve a stable, heat-controlled environment. This is typically done through pit firing, where a fire is built in a hole dug in the ground and the pottery is placed inside.
Preparing the Clay and Pit
For primitive pottery to be fired in a campfire, start by sourcing suitable clay. Look for clay with a high kaolin content, as this will help it withstand high temperatures. Mix the clay with a small amount of water to create a workable consistency, and then shape it into your desired form using the coil method. For a small project, aim for a 2-3 pound (0.9-1.4 kg) piece of pottery.
Firing the Pottery
Dig a hole that’s about 3-4 times larger than the size of the pottery. Build a fire in the center of the hole, using dry wood and kindling to achieve high temperatures. The fire should burn for about 30 minutes to an hour to reach the required temperature. Once the fire has burned down to embers, carefully place the pottery in the center of the pit. Cover the pit with soil and leaves to retain heat and create a stable environment. The firing process typically lasts 2-4 hours, depending on the temperature and size of the pottery. Monitor the temperature using a thermometer to ensure it reaches 1800-2000°F (980-1090°C), which is hot enough to achieve a stable, waterproof glaze.
Waterproofing and Cooling
Once the firing process is complete, carefully remove the pottery from the pit and let it cool slowly. Apply a waterproof coating, such as beeswax or plant resin, to protect the pottery from moisture. This will help extend its lifespan and prevent water damage. For added durability, consider applying multiple layers of the waterproof coating, allowing each layer to dry completely before applying the next.
