Within a year of Öhrström’s arrival at Orrefors he introduced the ariel technique, a variant on the graal technique. It involved the application of a pattern to a blank form through sandblasting. When the form was cased in a thin layer of glass, air was trapped in the sandblasted pattern, forming bubbles. Further layers of glass could then be added and the object was blown into its final shape. The ruby-red profile bust of a young girl surrounded by air bubbles and streaks within a mass of clear and refractive glass is typical of Öhrström’s production of the 1950s.
