This is an antique all blue and white sponge ware paneled mixing bowl; unsigned and imperfect. I believe this to be the embossed heart pattern by the Pfaltzgraff Company in York, PA. This size 14" bowl is very rare. It measures approx. 14" wide and is approx. 6" tall most of the way round. There are some stone pops through the glaze, kiln stilt marks inside, crazing, 2 noticeable linear cracks starting at the rim and one other that looks like an impact/indentation lower on the bowl.(see pic 6) At least 2 of them appear to have had some sort of old glue? applied to them. Despite these flaws it still displays nicely and would make a wonderful addition to any collection.
