Vintage Corning Ware Electromatic Immersible Platter P-54

This is a vintage Corning Ware Electromatic Immersible Platter, featuring the iconic 'Cornflower Blue' floral pattern against a white Pyroceram ceramic-glass body. The platter is rectangular with rounded corners and a slightly raised rim, designed to fit into an electric heating element or to be used as a standalone serving piece. The surface features the classic blue floral sprig centered on the lower half. This particular specimen is remarkable because it appears to be in its original factory plastic wrap, which includes the mid-century promotional graphic and text labeling it as 'Electromatic' and 'Immersible.' The graphics depict a stylized 1960s-era woman serving a turkey, emphasizing the item's utility for 'Family Meals or Entertaining.' The branding includes the classic Corning Ware star logo. Since it is still in the original protective film, the white ceramic surface appears pristine with no visible chips, cracks, or utensil marks. The plastic film itself shows some wrinkling and cloudiness consistent with long-term storage, likely dating from the 1960s to early 1970s. This item represents a high point in American mid-century kitchen technology and design, prized for its durability and thermal shock resistance.
