Trimming a wide rimmed Southern Ice porcelain bowl.

​Note how I start trimming. First the interior and then the exterior wall. It is easier to judge the wall thickness while trimming right side up and if the interior is perfect, the exterior can just follow.
I trim the foot with a blunt tool, because the clay is still very soft at this stage (I normally keep my pots under plastic until it releases itself from the bat), but first use a surform blade to take any unevenness out. The softness of the foot allows me to reshape the foot rim. For the walls I use a sharp trimming tool, to prevent that I have to push too hard on the thin rim.
I run the wet sponge over the whole piece to create a slip that help me to smooth the surface out with a rubber kidney, but at the same time, the re wetting of the pot will allow me to alter the shape later. Be aware that if the pot is to dry when one add water, it can de-laminate.
