Flavio Poli

Italian glass designer (1900-1984) who became artistic director of Seguso Vetri d'Arte on Murano in 1934. His postwar Sommersi, heavy vessels in which layers of intensely coloured glass are cased within one another, brought him wide recognition, including a Compasso d'Oro in 1954, and his Valve series explored bold, shell-like forms. Collectors look for pieces with strong colour contrasts and documented Seguso attribution.
