AI Appraisal Estimate

This set consists of two round nested storage bowls manufactured by Pyrex, crafted from durable tempered borosilicate or soda-lime glass with a distinct blueish-green tint. The larger bowl features a 'Mod Floral' or 'Whimsical Flower' pattern, characterized by large, stylized daisy-like blooms and concentric circles in navy blue and teal. The smaller bowl is adorned with a 'Mosaic' or 'Marrakesh' inspired medallion pattern, featuring intricate repeating geometric circles in teal and indigo. Both bowls are cylindrical with slightly tapered sides and thick, rolled rims designed to accommodate plastic airtight lids (lids not pictured). These pieces are contemporary, likely produced within the last 10 to 15 years, reflecting a modern-retro aesthetic inspired by mid-century patterns. The glass clarity is high, showing minimal scratching or 'clouding' from dishwasher use, and the screen-printed enamel graphics remain vibrant with no significant 'flea bites' or loss of pigment. No chips, cracks, or thermal shock fractures are visible, suggesting these items have seen light domestic use and have been well-maintained. The craftsmanship is consistent with high-volume industrial glassware production known for its heat resistance and durability.

I have conducted a visual examination of the two Pyrex glass storage bowls featuring navy and teal floral/geometric patterns. The items appear to be in excellent contemporary condition, exhibiting high glass clarity and vibrant enamel application without the typical 'dishwasher haze' or pigment loss common in pre-owned glass. Based on the design motifs and the specific blue-green tint of the glass, I identify these as modern production pieces (circa 2010–2020) rather than vintage mid-century opal glass. The current market for contemporary Pyrex is driven by utility and 'modern-retro' aesthetics. Unlike rare vintage patterns like 'Lucky in Love,' these mass-produced nested bowls are readily available. Comparables for this specific set in secondary markets (eBay, Etsy) typically sell within the $15 to $25 range per bowl, depending on the presence of matching BPA-free plastic lids, which appear to be missing here. This lack of original lids slightly depresses the value to secondary-market buyers looking for functional kitchen storage. While the visual data strongly suggests authentic Pyrex brand manufacture, full authentication is limited by the digital format. A physical inspection would be required to verify the 'PYREX' or 'pyrex' embossed backstamps (which distinguish between borosilicate and soda-lime glass) and to check for micro-scratches or 'flea bites' not visible in photographs. Provenance is not a significant factor for this category of modern household goods. For a definitive valuation, I would need to confirm the presence of any manufacturing mold marks and the set's completeness with original lids.
