Glass Bowl Uno Westerberg for Pukebergs Glasbruk, Ice Glass Technique, Sweden 1960s

Heavy, low glass bowl by Uno Westerberg for Pukebergs Glasbruk, made in Nybro in Sweden's Glass Country, 1960s. Clear glass in a 35 cm wide and 13 cm high wavy-edged shape that is more landscape than vessel — the rim curves in free hills and valleys, hand-folded on the hot glass, with the characteristic pinch points at the crests of the waves. In daylight, the bowl appears almost colorless.

The real fascination lies in the surface: both the inner and outer walls are continuously structured using the Isglas technique — hot glass is dipped into cold water, and the crack pattern that forms shock-like is then remelted. The result is a grainy, crater-like topography that breaks light into a thousand small reflections, making the bowl shimmer between an ice floe, a moon surface, and old bark, depending on the lighting. A signature craftsmanship technique of Swedish glass, produced in high quality at Pukeberg between the late 1950s and early 1970s.

Uno Westerberg (1914–1985) started at Arvid Böhlmarks Lampfabrik in Stockholm at the age of 21 and later became artistic director of Pukebergs Glasbruk. One of his overlaid table lamps is in the collection of the Museum of Modern Art in New York; his Spectra series — bowls and vases made of clear to greenish tinted glass with organic edges and structured surfaces — was exported especially to the USA and is now considered one of the most sought-after Westerberg lines. This bowl formally and technically follows the Spectra signature.

Collector's item for sideboard, library, coffee table, or display cabinet — solo as a sculptural object or filled with fruit, lemons, white stones, as a shallow water bowl with floating candles. A grand appearance for a restrained material, clear Swedish line, very good vintage condition without rim chips or cracks.
