When ceramic pieces are glazed and fired, the glaze becomes liquid at high temperatures. To prevent it from sticking to the kiln shelf and getting damaged, the bottom surface is sometimes left unglazed or supported by small pins.
This Porcelain Paper Plane has two edges that serve as its base. During firing, I place a pin support under the edge that would be held when holding a paper plane, and leave the other edge unglazed. Occasionally, I also sand areas where the glaze has slightly dripped, which can make the underside appear unglazed or slightly chipped in places.
However, since these characteristics occur on the underside of the piece as part of its sculptural nature, they are considered within the normal range of handmade variation.
Thank you very much for your understanding.
