Vintage Corning Ware Cornflower Blue Casserole Dish with P-7-C Lid

This is a vintage Corning Ware square casserole dish featuring the iconic 'Cornflower Blue' pattern, which consists of three blue flowers with green leaves on a solid white background. The piece is manufactured from Pyroceram, a high-durability glass-ceramic material designed to withstand extreme temperature changes from freezer to oven or stovetop. The dish includes small integrated tab handles extending from the rim. It is accompanied by a transparent Pyrex glass lid (likely a P-7-C model) with a centralized round knob handle and deep concentric rings. The lid shows visible amber-colored staining or baked-on grease residue along the inner rim, indicative of previous use and age. The white body appears to be in relatively good condition with the blue floral graphic retaining its color, though close inspection of the rim suggests minor utensil marks. This specific pattern was the first produced by Corning Ware, introduced in 1958 and becoming a staple of mid-century American kitchens. The craftsmanship is characterized by its heavy, dense feel and the smooth, non-porous finish of the Pyroceram material. The overall condition is good for a utilitarian kitchen item of this period, though the lid requires deep cleaning to restore optical clarity.
