Ivory Color was a name used on one of the first breakfast sets made for Quaker Oats in the mid-1920s. Sebring Potteries' Barbara Jane shape was used for this set which is a round rim shape with a wide fluted verge. Several potteries made Ivory Color including Sebring, Homer Laughlin, and Knowles. Pieces will have an "Ivory Color" backstamp with the initial of the maker. In Homer Laughlin's case, a capital letter "L" is located under the Ivory Color name.
Soon after the use of Sebring's Barbara Jane shape, HLC started to make breakfast sets with pieces from the Trellis shape. Initially, items were marked with the same Ivory Color backstamp before a new Trellis marking was made. Like the Barbara Jane shape, multiple companies made Trellis and often pieces are marked with a letter to signify the pottery. With both shapes, larger serving pieces could be purchased to make sets of dinnerware.
