Pyrex casserole dish (not authenticated)

This item is a covered round casserole dish constructed from white milk glass or tempered opal glass, paired with a clear glass domed lid featuring integrated loop handles. The primary body features a smooth, rounded profile with built-in side handles for lifting and is decorated with a blue floral and foliage motif known as the 'Cornflower' pattern printed on one side of the exterior. The piece displays physical characteristics consistent with mid-century American kitchenware production, typically associated with mass-market durable glassware. Regarding condition, there are minor surface scuffs and slight fading or wear to the blue painted design on the side, but the glass bodies appear largely intact without major structural cracks visible from this angle. No maker's marks or stamps are clearly legible in the provided photograph, though the overall form, white base color, clear lid, and distinctive blue floral motif are consistent with pieces produced by the Corning Glass Works under the Pyrex brand during the mid-to-late 20th century. The identification rests entirely on visual matching of the shape and decorative pattern rather than a verified hallmark or physical inspection.

Based on what I can see in the photograph, this covered round casserole dish exhibits visual characteristics consistent with mid-century kitchenware produced by Corning Glass Works under the Pyrex brand, specifically featuring the blue floral 'Cornflower' pattern on a white opal glass body with a clear glass lid. However, I cannot verify from a photo alone whether this is a genuine piece, a later reproduction, or an unmarked copy, as no legible maker's mark is visible and attribution must remain a working hypothesis. The value estimate provided assumes the identification is correct. In current secondary markets, mid-century kitchenware and vintage glass casseroles of this type generally trade within a modest price range depending heavily on condition. The minor surface scuffs and fading to the blue painted design observed here would pull the value toward the lower end of the spectrum. To confirm authenticity and establish a more precise valuation, I would need physical inspection to check for specific factory mold marks, hallmarks, or stamps. If this piece were determined to be a reproduction, replica, or an unattributed item in the style of mid-century ware, the market value would drop significantly, likely ranging from $10 to $15.
