Overview
An eye-catching Italian art glass decanter featuring a distinctive spiral 'screw' or 'bolt' neck rising from a heavy hexagonal base. This playful, sculptural design is a classic example of the mid-century modern glassmaking boom centered around Florence.
Story
Tuscan glassmakers in the 1960s transformed industrial hardware into high art. This decanter mimics a giant screw, turning a mundane workshop tool into a chic, light-catching conversation piece for the modern home bar.
Maker / Origin
While often unsigned, these whimsical decanters were produced by various glassworks in the Empoli region of Italy, such as Rossini or Stelvia. Empoli has been a hub of glassmaking since the 14th century, transitioning from rustic green glass wine flasks to vibrant, experimental decorative art glass in the post-war era.
Condition & Value
The decanter appears to be in good vintage condition with no major visible chips or cracks. There is some light cloudiness or residue visible inside the hexagonal base, which is common for vintage decanters but can be cleaned. The presence of the original stopper is a major plus. Minor cloudiness slightly tempers the value.
