Sculptural ice-like glass tray by Rolf Sinnemark for Kosta Boda, Sweden, 1980s.
A fragment of frozen motion — this glass piece by Rolf Sinnemark for Kosta Boda blurs the boundary between functional object and artistic gesture.
Entirely transparent, it reveals its complexity only through light. Depending on the angle and intensity, the surface shifts from crystal clarity to intricate patterns of shadow and reflection — a choreography of translucency. This piece was designed with different textures that evoke melting ice and fractured frost, it becomes a small-scale study of how matter can hold temperature, light, and time.
Cast in heavy glass with a textured base that feels carved rather than moulded, the piece merges precision and spontaneity, geometry and erosion. Part of Kosta Boda’s radical 1980s experiments in glass, Sinnemark’s design transforms functionality into perception — an object that inhabits both the domestic and the geological, both the everyday and the elemental.
A clear body that contains sculptural landscape.

Kosta Boda
Kosta Boda, founded in 1742 in the heart of Sweden, is a beacon of Scandinavian glassmaking, where craftsmanship meets experimentation. The objects in RARE.’s collection highlight a period when the studio embraced sculptural forms, transforming glass into both functional objects and artistic statements.
Rolf Sinnemark
Rolf Sinnemark (1924–2010) was a visionary Swedish designer whose work with Kosta Boda redefined glass as a sculptural and expressive medium. His pieces embody a bold exploration of form and texture, where the tactile qualities of glass become an essential part of their narrative.
RARE. collects this legacy — where glass is not just made, but sculpted into moments of tension and beauty.
