Simon Leach teaches the secret to glazing the inside of a bowl. You will need: brush, glaze, sponge, water, stick or whisk. Using a brush, dust the inside of the bowl to be glazed. Remove any clay that remains stuck on the bowl by using a blade or knife. Stir the glaze from the bottom using a stick or whisk Add water to the glaze if it appears too thick and stir again from the bottom. Pour the glaze into the bowl, careful not to get any over the edge. If any glaze goes over the edge of the bowl, take a sponge to wipe it off, as it is easier to clean immediately. Swirl the glaze around to coat the bowl and dump the excess glaze back into the container. Don't be afraid of the glaze and keep practicing. The more you practice, the better you will be.
