Wirkkala’s designs often reflect natural forms, translated into pure and elegant contours. The Kantarelli vases, based on the simple form of a chanterelle mushroom, were among the most popular designs introduced by Wirkkala and remained in production from 1946 until 1960. They have become icons of Finnish art glass of the 1950s. Wirkkala won a Grand Prix with this design at the 1951 Milan Triennale.
