How to Create Airtight Pots for Storing Food?

Preparing the Clay and Workspace

To start making an airtight pot, gather a mixture of 70-80% clay, 10-15% water, and 5-10% natural fibers like straw or plant fibers. Mix the components in a workspace covered with a non-stick surface, such as a sheet of plastic or a piece of bark, to prevent the clay from sticking. Knead the mixture until it becomes pliable and easy to shape.

Shaping and Molding the Pot

Use a coil-building technique to shape the clay mixture into a pot. Create a coil by rolling out the clay to a thickness of about 1-2 cm and then shaping it into a cylindrical shape. Repeat this process, overlapping each coil to form the body of the pot. Once the desired shape is achieved, use a tool or a piece of bark to smooth out any imperfections and create a uniform surface.

Firing the Pot

To achieve a waterproof seal, fire the pot in a pit at temperatures between 1000°C to 1200°C for several hours. Use dry wood and kindling to create a fire that reaches the desired temperature. Once the fire has burned down to a bed of hot coals, carefully place the pot in the pit and cover it with a layer of insulating material, such as leaves or sand, to maintain the heat. After several hours, carefully remove the pot from the pit and allow it to cool before testing its airtightness.
