Bi-Color Incalmo Flared Bowl
Decorative Art, Art Glass Vessel • Italian Murano School; style associated with Murano glass makers such as Venini or Carlo Moretti. Could also be a contemporary studio glass piece from the American studio glass movement influenced by Venetian techniques.
Style & Movement
Mid-Century Modern / Contemporary Studio Glass
Medium & Technique
Hand-blown glass using the incalmo technique (joining two separate components of hot glass) to create the dual-tone effect of translucent smoke/brown and opaque orange glass.
Creation Period
Late 20th to early 21st Century (c. 1970–2010)
Dimensions & Format
Approximately 8-10 inches in diameter at the rim; circular/conical format with a tapered base.
Subject Description
A functional but sculptural glass vessel featuring a dramatic flared rim. The piece utilizes geometric color blocking, splitting the bowl into two vertical halves of contrasting color and opacity: a transparent amber-smoke and a solid opaque vibrant orange.
Condition & Value Assessment
Condition Assessment
Good. High surface gloss remains, though some micro-scratches consistent with use and age are likely present on the interior and base.
Estimated Market Value
USD $250 - $600
Auction Estimate
USD $150 - $450
Provenance History
Likely acquired via secondary market or specialty glass galleries. No visible signatures or acid-etched marks are apparent in the provided image, common for certain production lines of high-end glass.
Art Historical Significance
The piece represents the enduring influence of Venetian 'Incalmo' techniques in modern design. This method was popularized by designers like Fulvio Bianconi and Gio Ponti, bridging the gap between centuries-old craftsmanship and modern industrial aesthetics.
Notable Features
The sharp vertical seam where the two colors meet indicates a high level of skill in glassblowing. The translucency of one half provides a unique optical effect when light passes through to the opaque opposite side.
Condition Issues
Visible dust and fingerprints on the surface. Minimal shelf wear/scuffing expected on the underside of the base where it contacts surfaces.
Conservation Recommendations
Clean with a soft, lint-free microfiber cloth and lukewarm water with mild detergent. Avoid abrasive cleaners or sudden thermal changes to prevent stress fractures in the glass.
