Vintage Corning Ware Blue Cornflower Casserole Baking Dish

This is a classic oven-to-table cookware item crafted from white Pyroceram, a glass-ceramic material known for its high thermal shock resistance. The dish features a square-to-rectangular profile with rounded corners and integrated tab handles. Its most defining characteristic is the iconic 'Blue Cornflower' (or 'Cornflower Blue') pattern silk-screened on at least two sides, consisting of three stylized blue flowers with green-like foliage radiating from a central point. The material has a high-gloss, milky white finish. This specific style of Corning Ware was most prevalent from the late 1950s through the 1980s. The surface appears to be in good used condition with a bright, intact graphic, though there are slight visible signs of grey metal markings on the exterior rim and lower edges, common for kitchenware of this age. Pyroceram is prized for its durability—able to move from freezer to stove or oven without cracking. The construction is solid and heavy for its size, indicating high-quality mid-century manufacturing standards. While a maker's mark is likely on the underside (not visible in the photo), the pattern is an industry standard for Corning Glass Works.
