Tomaso Buzzi for Venini, floor lamp, model '502', alga glass, brass, gold leaf, silver leaf, Italy, design 1933-35, made 1930s-1950s

Designed between 1933 and 1938 by Tommaso Buzzi for the renowned Venetian glass manufacturer Venini, this remarkable floor lamp ranks among the most refined examples of Italian Art Deco lighting. It belongs to a select group of objects created during Buzzi’s influential tenure as artistic director of the company and embodies the sophisticated synthesis of craftsmanship, innovation, and sculptural elegance that defined the period. Today, surviving examples are exceptionally rare, making the lamp not only a striking decorative object but also an important document of Italian design history.

Tommaso Buzzi (1900–1981) was one of the most versatile creative figures of twentieth-century Italy. Trained as an architect at the Politecnico di Milano, he worked across disciplines as a designer, graphic artist, writer, decorator, and architect, establishing a reputation for combining intellectual rigor with artistic imagination.

Early in his career, Buzzi became closely associated with Gio Ponti, under whose mentorship he trained professionally while developing a lasting friendship. Before graduating, he had already associated himself with the Studio di Sant’Orsola group, which included Ponti, Michele Marelli and Emilio Lancia. The group shared Buzzi’s passionate interest in the revival of classical architecture and artistic craftsmanship, traits evident in the Novecento movement and in Milanese Deco. Their designs reveal a deep appreciation for historical precedent while remaining unmistakably modern in their refinement and material sophistication.

The lamp’s stem and shade are crafted from Alga glass, a material developed during Buzzi’s tenure as artistic director of Venini & C., a position he assumed in 1932. In this role, he dedicated himself to expanding the company's design repertoire, pioneering novel glassmaking techniques such as the Alga and Laguna series. Alga glass is distinguished by its layered composition: a core of lattimo (milk glass) encased in a translucent, colored outer layer – green for Alga, pink for Laguna – and further enriched with an even application of gold or silver leaf. Variations of this design were produced in different color palettes, with or without gold or silver embellishments, or featuring subtle tone-on-tone applications of glass paste.

Structurally, the lamp’s ribbed stem is divided into three sections by elegant brass mounts, gradually widening toward the base to achieve a balanced, sculptural presence. The white glass lampshade, with its gracefully curved contours and expansive form, evokes the delicate silhouette of a tulip, enhancing the lamp’s organic yet refined aesthetic.
