CorningWare "Cornflower Blue" P-10-B Baking Dish

This item is a vintage CorningWare baking dish, commonly known by its iconic blue floral pattern, 'Cornflower Blue.' The dish is square or slightly rectangular with gently rounded corners, and features integrated handles on two opposing sides. Its exterior is a clean, glossy white, typical of CorningWare's Pyroceram material, which is a glass-ceramic composite known for its durability and heat resistance, allowing it to go from freezer to oven to table. The most distinctive feature is the 'Cornflower Blue' pattern applied to the exterior sides of the dish. This pattern consists of three stylized blue cornflower blossoms connected by delicate green leaves and stems, repeated on both long sides. The blue color is a vibrant, clear medium blue. The interior surface is also white and appears smooth and unblemished. Based on the pattern and style, this piece likely dates from the 1960s to the late 1980s, when the 'Cornflower Blue' design was a staple of American kitchens. The condition appears to be very good with no visible chips, cracks, or significant wear on the exterior decoration. There might be some minor scuffing or slight discoloration in the interior from use, common for vintage cookware, but this cannot be definitively assessed from the provided image. The craftsmanship is consistent with mass-produced but high-quality kitchenware of that era, prioritizing functionality and iconic design.

Based on my visual examination of the provided image, this CorningWare 'Cornflower Blue' P-10-B baking dish appears to be in very good vintage condition. The iconic 'Cornflower Blue' pattern, a hallmark of authenticity for this period, is clearly visible and shows no signs of significant wear or fading. The glossy white Pyroceram body seems intact, free from visible chips, cracks, or deep scratches that would dramatically diminish its value. The integrated handles and overall shape are consistent with authentic CorningWare pieces from the 1960s to the late 1980s. Market conditions for 'Cornflower Blue' CorningWare are relatively stable. While highly collectible, it is not particularly rare due to its widespread production. Smaller, well-preserved pieces like this one, especially with common patterns, typically command modest prices. Comparables on online marketplaces and at antique shops show similar dishes in this condition ranging from $20 to $50, with size and specific model numbers influencing the higher end. The P-10-B is a common size. Demand remains consistent among collectors and those seeking nostalgic kitchenware, but it does not drive premium pricing for standard items. Factors impacting value positively include its apparent excellent condition and the enduring popularity of the 'Cornflower Blue' design. Negative factors, if present, would be any hidden chips, cracks, or significant interior staining not visible in the image. For full authenticity verification, a physical inspection would be paramount. This would allow me to check for manufacturer markings on the base, assess the interior for discoloration, and feel for any hairline cracks or surface imperfections not discernible from a photograph. Provenance documentation, while rare for such items, could also add to its historical value. Given these considerations, I place the appraisal value in the $25-40 range.
