Corning Blue Roaster Appraisal

Vintage Corning Ware Cornflower Blue Roaster Pan

This is a vintage rectangular roasting or baking dish manufactured by Corning Ware, featuring the iconic 'Cornflower Blue' floral design. The item is constructed from Pyroceram, a glass-ceramic material known for its high thermal shock resistance, allowing it to move directly from the freezer to the oven or stovetop. The pan is a solid opaque white with a glossy finish, featuring a central decorative motif on the long side consisting of three blue cornflowers with slender leaves. This pattern was the first and most popular produced by Corning Ware, typically dating from the late 1950s through the 1980s. The shape is rectangular with gently rounded corners and slightly flared sides. This specific model, likely a P-21 or P-19 roaster, is designed without handles for a streamlined profile. The surface appears to be in very good condition with a high luster and no visible chips, deep scratches, or significant 'silvering' from metal utensil marks often found on vintage pieces. The blue floral stamp remains vibrant and intact without any fading or loss of detail. There is no visible crazing or heat staining on the interior or exterior walls, suggesting it has been well-maintained and likely used sparingly. The underside, while not fully visible, would typically feature a glass-stamped maker's mark indicating the model number and capacity.
