Barovier and Toso, Luster, Mount Fontana Arte, circa 2000, Italy

Partnerships come and go within the community of glass-making artisans on the Venetian island of Murano, where business relationships seem as complex as the shifting alliances in the notoriously acrimonious Italian parliament. Formed in 1942 by members of families with centuries of experience in the craft, Barovier, Toso & Co. has proven to be one of the most enduring and prosperous Italian glass manufactories of recent decades. Under the nearly 50-year artistic directorship of cofounder Ercole Barovier (1889–1974), the company created buoyant traditional pieces such as chandeliers and sconces, and it pioneered an array of innovative modernist designs with bold colors, patterns and surfaces.

To appeal to gentler, more conservative tastes, Barovier Toso produced a range of lilting, sinuous lighting pieces that are often described as embodying “Liberty Style” — the Italian term for Art Nouveau, taken from the name of the famed London department store that promoted 19th-century organic textile designs in the manner of William Morris. The hallmarks of the style in Barovier & Toso works are elements of glass in the shape of thick leaves, fronds and flower petals, deployed along with other naturalistic ornament in sconces, pendants and chandeliers.

Ercole Barovier began his personal aesthetic transition toward modernism in the 1930s with his Primavera series of vases and animal sculptures — idiosyncratic milky-white and clear glass filled with tiny bubbles and hairline interior fissures that he produced for Artisti Barovier, a firm headed by his father and uncle. Later, with Barovier Toso, he would explore such novel styles as the mosaic-like Pezatto glass; fluid Spiral patterns; the pebbly textured Barbarico line and the complex, layered and highly colored abstractions of the Oriente series of vases and bowls.

Traditional or modern, Barovier Toso — still under family control — has produced one of the finest and most diverse catalogues of Murano glass in the last 100 years.

Best known for its elegant and innovative vintage lighting fixtures, the Milan-based firm Fontana Arte pioneered one of the key features of 20th-century and contemporary Italian design: the union of artistry and industry wrought by partnerships between creative talents — chiefly architects — and entrepreneurial businesses. Fontana Arte is further distinguished by having had as artistic director, in succession, four of Italy’s most inventive modernist designers: Gio Ponti, Pietro Chiesa, French transplant Max Ingrand and Gae Aulenti.

The bread and butter of the glassmaking company that Luigi Fontana founded in 1881 was plate-glass panels for the construction industry. In 1930, Fontana met Ponti — then the artistic director of the Richard Ginori ceramics workshop and the editor of the influential magazine Domus — at a biannual design exhibition that became the precursor to today’s Milan Design Triennale, and the two hatched an idea for a furniture and housewares firm. Fontana Arte was incorporated in 1932 with Ponti as its chief of design. He contributed several lamps that remain among the company’s signature works, including the orb-atop-cone Bilia table lamp and the 0024 pendant — a stratified hanging sphere.

The following year, Fontana Arte partnered with the influential Milan studio glassmaker and retailer Pietro Chiesa, who took over as artistic director. Chiesa’s designs for lighting — as well as for tables and items including vases and ashtrays — express an appreciation for fluidity and simplicity of line, as seen in works such as his flute-shaped Luminator floor lamp and the 1932 Fontana table — an arched sheet of glass that is held in the permanent collection of the Museum of Modern Art.

Six years after Chiesa’s 1948 death, the École des Beaux Arts–trained Max Ingrand took over as head of design at Fontana Arte. Ingrand brought a similarly expressive formal sensibility to wares such as lamps and mirrors, but he also had a masterful eye for the manipulation of glass surfaces — whether they be cut, frosted, acid-etched or sand-blasted. His classic design is the Fontana table lamp of 1954, which has a truncated cone shade and curved body, both of which are made of pure, chic white-frosted glass.

Following Ingrand, the often-audacious Italian architect Gae Aulenti served as the company’s artistic director from 1979 to 1996, and while she generally insisted that furnishings take second place aesthetically to architecture, she made an exception for Fontana Arte pieces such as the Tavolo con Ruote series of glass coffee and dining tables on wheels, bold lighting pieces such as the Parola series and the Giova, a combination flower vase and table lamp. As a key incubator of modern design under Aulenti’s tenure, Fontana Arte remained true to its long-held commitment — creating objects that have never been less than daring.
