Each bottle begins as a thrown porcelain form that is carefully trimmed on the potter's wheel and coated with a thin layer of terra sigillata. After an initial bisque firing, copper is applied to the surface and the vessel is wrapped in a lot of fresh seaweed that is secured with wire. The seaweed contributes a rich variety of salts and minerals that react with the clay and copper during firing, producing unexpected flashes of color and subtle surface variations.

The bottles are then fired in an open bonfire fueled by wood. As the fire intensifies, additional wood is added until the vessels reach the same glowing color as the surrounding flames. During this process, the interaction of clay, copper, seaweed, ash, flame, and atmosphere produces surfaces that are both intentional and unpredictable. The fire leaves distinctive marks, flashes of color, and nuanced variations that cannot be fully controlled. After cooling overnight, the bottles are cleaned and sealed with a clear finish. Each piece bears the unique record of its experience with the fire, reflecting both the maker's hand and the transformative forces of the firing itself.
