The WA is a GR pottery Forms accessory that allows the maker to attach it to a potters wheel to aid in cutting an even lip, helps in developing a thrown foot, and gives the plate support in drying. A standard round GR Pottery Form then attaches to the spacer pin with the form's center hole (as of March 2018 a center hole comes with every round form). The center hole allows the maker to push from bottom to not disturb the lip.
