Can Primitive Pottery Be Used for Both Cooking and Storage?

Choosing the Right Clay

When selecting clay for primitive pottery, it’s essential to choose a type that is free of contaminants and has a suitable consistency for coil-building. In general, a mix of 70-80% clay, 10-20% sand, and 5-10% silt is a good starting point. For cooking vessels, it’s best to use a clay with a high kaolin content, which will provide a more durable and water-resistant finish. In the wild, you can collect clay from riverbanks, lake beds, or areas with exposed soil. Be sure to test the clay for its plasticity and workability before using it for pottery.

Pit Firing for Cooking Vessels

Pit firing is a primitive technique used to fire pottery at high temperatures, often exceeding 1000°C (1832°F). This process requires careful planning and execution, as it can be unpredictable and may result in uneven heating. To achieve a good firing, you’ll need a pit with a diameter of at least 1.5 meters (4.9 feet) and a depth of 0.5-1 meter (1.6-3.3 feet). The fuel of choice is usually dry wood or charcoal, which should be arranged in a teepee shape inside the pit. Once the fire is burning steadily, cover the pit with a layer of soil and let it cool slowly overnight.

Waterproofing and Storage

To make primitive pottery suitable for storage, you’ll need to waterproof it using a combination of techniques. One method is to apply a thin layer of natural wax, such as beeswax or plant resin, to the interior surface of the vessel. Another approach is to use a mixture of clay and plant material, such as rice flour or cornstarch, to create a breathable seal. For added protection, you can also apply a layer of natural varnish, such as linseed oil or turpentine, to the exterior surface of the vessel. When storing food or liquids in a primitive pottery vessel, be sure to dry it thoroughly before use and avoid exposing it to extreme temperatures or physical impacts.
