Trimming excess clay off the bottom of a pot not only makes the pot lighter in weight but also refines the shape and adds interest to the pot. A footring (or foot) is a raised circle of clay at the base of a thrown pot on which the pot will stand and is a typical end product of trimming. Sometimes trimming a foot can actually take longer than throwing the pot!
To trim a foot you must wait until the pot has air dried a bit to the leatherhard stage (clay is no longer malleable, but will crack or distort if pressure is applied). Trying to trim a foot onto a pot that has just been throw will end in utter disaster since the pot will collapse under its own wet weight.
