These are tahor among the earthenware utensils: A tray that has no rim, an open-sided firepan, a toaster’s pan, pipes — even though [they are] bent [and] even though [they are] capable of containing, a kavkav made for a bread basket, a tefi which was adapted for [covering] grapes, a barrel for swimmers, a barrel-[shaped handle] set into [the wall] near the bottom of a machatz, a bed, a chair, a bench, a table, a ship, and a candelabra, [all] made of earthenware, are tahor. This is the general rule: Any of the earthenware utensils which have no interior, have no [decree of tumah upon their] exterior.
