Blue Cornflower Casserole Appraisal

Vintage Corning Ware Blue Cornflower Casserole Dish

This is a classic mid-century square-shaped casserole dish manufactured by Corning Ware, featuring the iconic 'Blue Cornflower' pattern. The vessel is constructed from white Pyroceram, a glass-ceramic material known for its high resistance to thermal shock, allowing it to move directly from freezer to oven. The design features a trio of stylized blue flowers at the center of the side panel, flanked by symmetrical blue leaves. The dish includes two integrated side handles (lugs) for handling. It is topped with a clear, tempered glass 'Pyrex' lid with a recessed circular knob handle. Physically, the item exhibits the smooth, opaque white finish characteristic of vintage Corning Ware. The condition appears to be very good with minimal visible scuffing; however, there are slight dark residue marks visible along the interior rim and outer edges where the lid meets the base, common with age and use. The pattern remains vibrant without significant fading. This specific 'P-series' styling suggests a manufacture date between the late 1950s and the early 1970s, representing a staple of American kitchenware history and mid-century modern utilitarian design.
