This circa 1906 antique Agate graniteware dough bowl is jumbo sized at 16 inches diameter (not including the handles) by more than 7 inches deep. I stopped measuring capacity at 12 quarts - it still had at least an inch and half to the rim. The bowl has a handled, vented lid and is marked Extra Agate Nickel Steel Ware L & G Mfg Co. There are some enamel chips as shown but no dent or dings, it's heavy and quite sturdy. Marked on the bottom as shown in the last photo.
