This form is variously referred to as a porringer or bleeding bowl. Contemporary metal examples in pewter or silver also have a single pierced handle. The pierced hole in the present example would not do much to aid the person holding it, whether it was to catch blood they were letting or when feeding an invalid so perhaps the hole was simply intended to aid storage, where it could be suspended on a hook.
