Pressed glass bowl in the style of Depression-era manganese or uranium glass

This item is a circular pressed glass bowl with a scalloped or 'crimped' rim, featuring intricate floral and geometric patterns. The vessel is decorated with stylized long-stemmed flowers, possibly daisies or cosmos, interspersed with panels of diamond-point or hobnail-style cross-hatching. The central well of the bowl also contains a floral motif. In the provided image, the bowl exhibits a vibrant green fluorescence when subjected to 365nm UV light. While the owner identifies this as clear glass under normal lighting, the strong green glow is consistent with glass containing manganese (which can glow under 365nm) or uranium dioxide (though uranium typically glows under 395nm). The construction appears consistent with American pressed glass manufacturing from the early-to-mid 20th century. No maker's marks or signatures are visible in the image, so an attribution to a specific factory like Fenton, Imperial, or Jeanette remained a hypothesis subject to in-person verification. The condition appears fair, with consistent light diffraction on the edges, though no large chips or cracks are immediately apparent. The craftsmanship is typical of mass-produced decorative glassware of the Depression era.

Based on my examination of the provided images, I have evaluated this circular pressed glass bowl with a scalloped rim and floral motifs. While I cannot verify the exact chemical composition from a photo, the green fluorescence under 365nm UV light suggests the presence of manganese or potentially low-level uranium. Per user submission, the item is identified as clear glass under normal light; if this is accurate, the glow likely indicates manganese-tinted glass common in the early-to-mid 20th century. I cannot confirm a specific manufacturer such as Fenton or Jeanette without a visible maker's mark or physical examination of the mold quality. My estimate assumes the piece is a period-accurate example of American pressed glass from the Depression era. The fair condition, noted by light diffraction and common wear, places it in a modest price bracket. The market for general depression-era glassware is stable but saturated, with highest demand reserved for rare patterns or verified uranium 'Vaseline' glass. This value range represents what a similar piece might achieve in a retail or secondary market setting if the attribution to the mid-20th century holds true. To confirm this identification, an in-person inspection of the 'seam' lines and a 395nm UV test would be necessary. If the piece is found to be a modern reproduction or lacks the suspected elemental signatures, the value would likely decrease to the $10-$15 range as a purely decorative object.
