Seguso Vetri d'Arte, originally named Artistica Soffiera e Vetreria - Barovier Seguso & Ferro, was formed in 1933 by Antonio Seguso and his sons Archimede and Ernesto, Luigi "Olimpio" Ferro, and Napoleone Barovier. Archimede Seguso was the master glassblower. Alberto Seguso, an accountant, joined as a partner in 1934. Flavio Poli also joined in 1934, as artistic director, and became a partner in the company when Luigi Ferro left in 1937. At this time, the name was changed to Seguso Vetri d'Arte s.n.c In 1939, the factory merged with Ing. Francesco Zecchin - Vetri Artistici e Mosaici, a company they had previously collaborated with, and Francesco Zecchin became a partner of SVA. Francesco left in 1940, when he was called to serve in the war, and Alberto Seguso left in the same year. Archimede Seguso left in 1942 due to ill health. Three new master glassblowers joined as partners in 1945: Francesco Martinuzzi, Guido Seguso and Giusto Nichetto. In 1946, as production increased, three more glassblowers joined as partners: Plinio Pustetto, Umberto D'Este and Angelo Seguso. Due to increasing taxes for limited partnerships, in 1949 the company was liquidated, and at this time Francesco Martinuzzi and Guido Seguso left to found Seguso dalla Venezia. The remaining partners then founded a new company, Seguso Vetri s.r.l, changing to Seguso s.r.l in the same year. Napoleone Barovier retired in 1950. This was the year Flavio Poli began to experiment with the sommerso technique, for which he became most famous. Mario Pinzoni joined the factory in 1953, as assistant to Flavio Poli. Plinio Pustetto left in 1958 due to health problems. In 1959 the factory name was changed to Seguso Vetri d'Arte s.a.s di Ernesto Seguso, Flavio Poli & C.i. Flavio Poli and Ernesto Seguso both left the company in 1963, and Angelo's sister Angela Seguso joined as a partner. At this time the name was changed to Seguso Vetri d'Arte s.a.s di Bruno e Angelo Seguso & C.i, and Mario Pinzoni replaced Flavio Poli as artistic director. Angela Seguso left in 1967, and Bruno Seguso in 1969. The name was then changed to Seguso Vetri d'Arte s.a.s di Angelo Seguso & C. Mario Pinzoni left in 1971, and was replaced by Vittorio Righattieri. Production ceased in 1973 and the company was put into liquidation.
