AI Appraisal Estimate

This item is a clear glass bowl, most likely a piece of Mid-Century Modern glassware such as those produced by Scandinavian makers like Holmegaard or Iittala. The bowl features a distinctively organic, rounded triangular (or 'tri-lobed') rim shape, which was a hallmark of 1950s and 60s Nordic glass design. A critical defining characteristic is the intricate, fine-lined etched or silk-screened pattern of white concentric and intersecting lines that create a web-like or linen-textured appearance throughout the glass. The glass appears to be of high quality with a thick, weighted base that displays a clear, polished pontil area. Notably, there is a remnant of an original paper or foil manufacturer's label centered in the bottom of the bowl, though it is currently torn and illegible. The overall condition looks good with no visible chips or cracks, although the partial label suggests it was used or cleaned previously. The craftsmanship indicates a refined mold-blown or hand-finished process common in mid-20th-century art glass.

I have virtually examined this mid-century modern art glass bowl, specifically looking for hallmarks of the Holmegaard 'Akva' or 'Linen' series, as the white filigrana-style inclusions suggest. The tri-lobed, organic shape and the heavy, controlled base indicate high-quality craftsmanship consistent with 1960s Scandinavian production. The remnant of the foil label, while illegible, supports a mid-century origin. Visually, the piece appears to be in 'Good' to 'Very Good' condition, with no evidence of fleur-de-sel clouding or significant rim abrasions. The market for Nordic glass remains stable, with specific interest in textured and patterned glass from this era. Comparables for signed Per Lütken or Otto Brauer pieces with similar 'linen' etching fetch premium prices in boutique auctions. However, the damaged label and lack of a visible signature on the base slightly temper the valuation. Importantly, this appraisal is based on photographic evidence alone. Full authentication requires an in-person inspection to verify the tactile quality of the etching, look for microscopic 'shelf wear' on the base consistent with age, and examine the glass under UV light to check for modern repairs or resin fills. Documented provenance or a clearer label would be necessary to reach the high-end estimate of $650.
