We don't find marked yellow ware bowls all that often and certainly not ones by National Pottery, one of the companies located on Potters Alley in Roseville, Ohio in the early 20th century. They made utilitarian pottery like bowls, cookware and flower pots for about 20 years. We found National Pottery listed in Chilton's Hotel Supply Index published in 1922; in a Popular Science Magazine classified ad published in 1923 and The Thomas Register of American Manufacturers in 1922. By 1925 they were operating two potteries, one down the street from the other, but a major fire in 1938 brought an end to the operations.
The mark on this bowl, "NATIONAL," is impressed on the bottom inside the foot ring. It has three outer chocolate brown bands and is made of thick, buttery yellow clay with a lovely glossy glaze. Measurements are 7 1/2 inches across the top, tapering to a 3 3/4 inch diameter base, about 3 inches in height and a weight of 1 1/2 pounds. Other than the usual glaze pops, pinholes and stilt marks typical of these homespun wares, this piece has underglaze discolorations around the rim both inside and out. There are no chips, cracks or repairs. (The "dent" you see on the rim is in the clay itself, made during the potting; it's not a chip). We recommend that the bowl not be used with wet ingredients, but placed on a shelf for vintage decor or used to hold dry stuffs like fruit or nuts. It's an exciting find for the serious collector of yellow ware or American pottery.
