Teal Bubble Glass Tall Tumbler

This is a tall, cylindrical drinking vessel crafted from transparent teal-colored art glass. The piece is characterized by a prominent 'bullicante' or controlled bubble technique, featuring numerous distinct air bubbles trapped throughout the thick glass walls. The rim is flat-cut and polished, and the base is heavy with a concentrated pool of aqua glass, showing a slight concave kick-up on the bottom. The vessel stands upright with a slightly tapered profile, typical of hand-blown or heavy mold-blown glassware. There are no visible maker's marks, signatures, or stamps anywhere on the exterior or base of the object. The overall physical condition appears to be good with no obvious chips, cracks, or heavy scratches visible in the photograph, displaying a clean surface gloss and light refracting properties consistent with mid-century modern Scandinavian or Murano-style decorative glassware. The owner has provided additional context describing the piece as a 'tall tumbler,' which is unverified by physical inspection. The attribution of this item is based solely on its visual characteristics, color, and bubble inclusion technique, without any manufacturer's documentation.

Based on what I can see in the photograph, this tall tumbler features a striking teal color and controlled air bubbles, or 'bullicante', which are characteristic traits often associated with mid-century modern Scandinavian or Murano art glass. The owner identifies this as a 'tall tumbler,' though I can't verify its precise function or manufacturer from a photo alone due to the lack of visible signatures, maker's marks, or labels. Physical inspection would be required to evaluate the glass density, pontil mark, and exact manufacturing techniques. Assuming the working hypothesis that this piece originates from a mid-century European studio producing work in this style, a fair market estimate for an item of this type falls in the $150–$300 range, driven by steady collector demand for decorative mid-century glassware. However, if physical inspection reveals this to be a later reproduction, replica, or an unmarked piece merely created 'in the style of' mid-century art glass, the value would likely decrease to the $40–$80 range. To better understand this piece, one would need an in-person examination by a glass specialist, combined with research into potential export labels or documented forms to support the attribution.
