Simon Leach of Simon Leach Ceramics shows how to finish a lidded box, thrown on a potter's wheel. When cutting into the box, make sure to do so with a cut slanting downwards so that the lid is less prone to falling off. Proceed to smooth off the exterior of the box, beginning where the two halves meet. Once the outside is smoothed, the fit of the two parts is probably not perfect, and so the joint between the two can be smoothed off. Carved features such as scalloped footing may now be added. Finally, if the lid is still prone to slipping, spigots may be added to the inside of the base to ensure a good fit. Following these steps will ensure your ceramic box is both practical and good looking.
