My favorite vessel for wheel thrown pottery is the bowl. There’s something dramatic about how the shape is pulled upward and outward from a ball of clay. One has to overcome gravity that wants to collapse the shape. Yet if the wall is too thick, the bowl feels clunky and heavy.
I’m not really sure if there’s height to diameter ratio that works better than others. The arc of the curved wall can act like a wild card, making most any shape workable.
Though often fairly small, the foot ring can make the pot. It’s more than just the base. Its proportions and shape are a counterbalance to the structure of the bowl.
