Mint condition pewter bleeding bowl. Designed to measure the amount of blood removed from patients. These bowls can be differentiated from standard pewter porringers by the graduated rings and ounce markings.
Pewter bleeding bowl designed with a flat side opposite the handle. This was thought to facilitate getting the bowl closer to the patient to catch all of the "let" blood.
Beautiful late 17th century, early 18th century pewter bleeding bowl. Unmarked, probably English in origin.
