AI Appraisal Estimate

This is a vintage small bowl or creamer, likely from the Pyrex 'Blue Filigree' or 'Scroll' pattern line produced by Corning Glass Works. The item is constructed from thick, durable opal glass (milk glass) with a distinctive blue-tinted exterior glaze on the upper half. The decoration features an intricate, lace-like scrollwork or filigree pattern in a darker blue ink, encircling the rim. It has a tapered circular form, narrowing toward a small, flat-bottomed base. The interior remains brilliant white, characteristic of high-quality opalware. Based on its design and material, this piece likely dates to the mid-20th century, specifically the 1960s or 1970s. The craftsmanship shows the classic uniform thickness and smooth finish associated with machine-pressed glassware of that era. Regarding condition, the blue transfer pattern appears slightly faded or worn in sections, a common result of automatic dishwashing or abrasive cleaning. No significant chips, cracks, or deep surface scratches are immediately visible, though minor shelf wear on the bottom footing is expected for a utilitarian item of this age. While no maker's mark is visible from this angle, pieces of this design typically carry a raised Corning/Pyrex stamp on the underside of the base.

I have virtually examined this vintage opal glass creamer, identified as the Pyrex 'Blue Filigree' pattern, often associated with the 'Old Town Blue' or 'Butterfly Gold' era accessory lines from the late 1960s to early 1970s. The piece exhibits the standard characteristics of Corning Glass Works opalware, including the high-gloss white interior and tapered profile. My visual inspection indicates moderate wear on the blue transfer design, likely due to chemical etching from dishwasher use, which is a common condition issue for this specific pattern. The absence of visible chips or 'flea bites' on the rim is a positive factor, though the fading of the filigree significantly prevents it from reaching 'mint' valuation. The market for mid-century Pyrex remains stable, but mass-produced accessories like this creamer are relatively common compared to limited-run nesting bowls or promotional patterns. Recent sales of similar 'Blue Filigree' pieces place the value in the $15 to $25 range. Authenticity appears consistent with factory-pressed glass, but a definitive valuation requires a physical inspection to check for the raised 'Pyrex' or 'Corning' backstamp on the base and to rule out micro-fractures not visible in photographs. To fully authenticate this item and verify its condition as 'excellent,' I would need to observe the piece under UV light to check for restorations and perform a tactile inspection of the glaze's integrity.
