Overview
A striking, large-scale glass bowl featuring a continuous concentric ribbed design that creates a mesmerizing optical ripple effect. The pale green-tinted glass captures light beautifully, showcasing the clean lines and functional elegance characteristic of mid-century modern design.
Story
Introduced during the post-war design boom, these concentric glass rings were engineered to mimic water ripples. This minimalist aesthetic transformed everyday household glassware into functional, light-bending sculpture.
Maker / Origin
If Scandinavian, this style is heavily influenced by legendary designers like Aino Aalto for Iittala, who pioneered functionalist glass in the 1930s. If American, it represents the mid-century output of companies like Dunbar or Blenko, who adapted European modernism for the American table.
Condition & Value
The glass appears clear with no major clouding, though there are minor surface scratches consistent with age and use. No visible chips or cracks along the rim, which is excellent as these ribbed edges are prone to flea bites. Good condition overall.
