Murano Clam Shell Bowl Value Guide

This mid-century Murano Clam Shell Bowl is a quintessential example of 1950s Italian artistry, featuring a biomorphic form and a serene aquamarine tint. Hand-blown by master glassmakers in Venice, these sculptural pieces represent the peak of the 'sommerso' and 'bullicante' techniques popularized by firms like Seguso.

What affects the value of Murano Clam Shell Bowl?

• The presence of an original foil label from makers like Archimede Seguso or Barbini significantly increases market value.
• Condition is critical; any chips, 'flea bites' on the edges, or heavy base scratches will reduce the $160-$175 valuation.
• The complexity of the glass-blowing technique, such as the inclusion of controlled bubbles or layered colors, affects desirability.
• Provenance and attribution to a specific mid-century Italian designer can drive prices toward the higher end of the range.

How to Identify Murano Clam Shell Bowl?

• Look for a polished pontil mark on the base, indicating the piece was hand-blown rather than mold-made.
• Examine the glass for the characteristic weight and clarity of high-quality lead crystal used by Murano masters.
• Check for the organic, asymmetrical biomorphic folds that define the authentic 1950-1960 clam shell silhouette.
• Identify the specific translucent aquamarine tint which should be consistent throughout the body of the glass.

History of Murano Clam Shell Bowl

Originating from the island of Murano, Venice, this style of glass became an international sensation during the mid-20th century. Master glassmakers like Alfredo Barbini and firms such as Seguso and Archimede Seguso specialized in the 'bullicante' or 'sommerso' techniques, often drawing inspiration from aquatic life and organic shapes to create sculptural home accents.
